Abstract: A lifting bar (12) for breaking scored glass sheets along score lines extending in the X direction and a device (30) for breaking the glass sheets along score lines extending in the Y direction are provided at a glass breaking table (1), conveyor belts (10, 11, 20, 21) being included in order to move the scored and/or partially broken glass sheets to the various locations of the glass breaking table (1). Additionally, rim snap-off tools (50 and 60) are associated with the glass breaking table (1), these tools breaking off marginal strips located outside of score lines corresponding to zero lines from the glass sheet by twisting these marginal strips with respect to the glass sheet. The procedure herein is such that first the marginal strips extending in the X direction are broken off by the rim snap-off tool (50) before the glass sheet is broken along the score lines extending in the X direction.

Abstract: Linerless labels are cut or burst from a web by passing the web through infeed and outfeed pairs of rolls with a separator device located therebetween. Each roll pair includes a friction surface for engaging the slick smooth surface of the web and another roll with a silicone elastomeric or plasma-coated surface for engaging substantially without gripping the exposed adhesive side of the linerless label web. In the cutting mode, a rotary blade severs the web against a fixed blade to form the label. The infeed rolls are backed up after each cut to break the adhesive bond between the web and the fixed blade and then reverse to advance the web through the cutting position and into the outfeed rolls for a subsequent cutting operation. The outfeed rolls continue to advance the cut linerless label to a receiving station. In a bursting mode, the web is perforated and a roller breaker bar is disposed between the infeed and outfeed rolls to break the web along the perforations to form the linerless label.

Abstract: A method and apparatus for curved-angle cleaving of optical fibers is presented. The method requires the introduction of a flaw in an optical fiber to be cleaved, and the application of predetermined stress and strain to the optical fiber in the vicinity of the flaw to cause curved-angle cleaving of the optical fiber at the flaw. More particularly, one embodiment of the method requires fixing first and second portions of the optical fiber, for example, by clamping, and introducing a flaw into the optical fiber between the first and second portions. Then, a substantially concentrated force is applied to the optical fiber between the flaw and the first portion of the optical fiber, on a side of the optical fiber opposite the flaw, in order to cause the optical fiber to cleave with a curved-angle cleave. Another embodiment of the method applies a substantially concentrated force to the fiber before introduction of the flaw.

Abstract: Apparatus uses a burster method to bow a continuous web of inserts and thereafter separates the forwardmost insert from the continuous web. A pair of feed rollers advances the forwardmost insert along a predetermined path toward a pair of burst rollers. Upon receipt of the forwardmost insert, the burst rollers first operate at a decreased relative speed with respect to the advancing speed of the web, thereby bowing the continuous web of inserts. The burst rollers then operate at an increased relative speed with respect to the feed rollers, thereby separating the forwardmost insert.

Abstract: Apparatus that uses the burster method for positioning coupons from a continuous web at a predetermined time at a predetermined location for insertion is disclosed. Positioning roll means define a bight to receive the leading edge of a coupon and are driven by positioning drive means at a continuous predetermined speed. Feeding roll means located upstream of the positioning roll means in the excess of one coupon length are driven by intermittent feeding drive means at a speed substantially less than the speed of the positioning roll means. Controlling means actuate and deactuate the feeding drive means in response to timing means related to container position and coupon sensing means at a sensing position between the positioning roll means and the feeding roll means.

Abstract: A burster for continuous single part business forms having a paper weight of about 32 lbs. or less utilizes a conventional transport mechanism, high speed rolls, and breaker blade. The slow speed rolls are substantially smooth surfaced (no axial grooves) and are mounted so that there is a fixed gap between them of 0.005-0.008 inches, which gap can be adjusted prior to machine operation. With this fixed gap, bubble formation in the business forms being burst does not occur, and there is no reason to use a servo or stepper motor to cycle the slow speed rolls apart and together. The high speed rolls are spring biased together and the transport mechanism includes a tractor pin feed drive located upstream of the slow speed rolls, a set of driven pull rolls between the tractor pin feed drive and the slow rolls, and a transport belt assembly. Spaced sheet metal plates may be used in place of the slow speed rolls.

Abstract: Interstacked longitudinally offset form sets from continuous webs are fed through upstream low speed rollers and downstream rollers, with a breaker bar disposed between the roller pairs. The upper roller of the slow roller pair is mounted eccentrically to engage the webs between the upper and lower rollers of the slow roller pair once for each revolution of the upper roller. When a leading portion of one web enters the nip of the downstream rollers, the eccentrically mounted upper low speed roller engages the webs and the downstream roller pairs are rotated at a higher speed to create sufficient tension in the form between the pairs of rollers such that the form engages against the breaker blade to burst the form from the web. Upon bursting, the eccentric low speed roller disengages or opens relative to the webs and the leading portion of a form of the other web engages in the nip of the downstream roller pair whereupon the bursting of the form from the second web is accomplished.

Abstract: Apparatus that uses the burster method for positioning coupons from a continuous web at a predetermined time at a predetermined location for insertion is disclosed. A positioning roll pair defines a bight to receive the leading edge of a coupon and are driven by a positioning drive at a continuous predetermined speed. Feeding rolls located upstream of the positioning roll pair in the excess of one coupon length are driven by an intermittent feeding drive at a speed substantially less than the speed of the positioning roll pair. Controlling mechanisms actuate and deactuate the feeding drive in response to a timing mechanism related to container position and a coupon sensing mechanism at a sensing position between the positioning roll pair and the feeding rolls.

Abstract: During the feeding of offset continuous collated business form webs to the slow rollers of a burster, it is important to insure that the top web properly passes through the slow roll section. By providing a number of puller wheels having aluminum cores and sawtooth rubber coverings atop conveyor belts passing over crowned pulleys which are oversped relative to the web speed, proper feed to the burster is provided. Form deflecting fingers extending from the puller wheels to the burster also help. In order to prevent the conveyor belts from running off the crowned pulleys an aligner is provided which has a number of vertical dowel pins with plastic sleeves covering and rotatable with respect to the dowel pins, disposed on each side of a conveyor belt associated with a crowned pulley and puller wheel. The aligner is provided immediately upstream of a rubber covered drive roll for the conveyor belts.

Abstract: Linerless labels are dispensed from a roll and detached along perforation lines using a set of low speed rolls, a set of high speed rolls, and a breaker blade between the sets of rolls. The label-engaging tip of the breaker blade, and at least one roll of each sets of rolls, has a surface that will not stick to the adhesive associated with the linerless labels. One or more conveyor belts, also with non-stick surfaces, may transport the linerless labels from the low speed rolls to the high speed rolls, and transport detached labels away from the high speed rolls. A sensor downstream of the high speed rolls senses the presence of a detached label, and then shuts down both sets of rolls. The apparatus may be operated in an automatic mode so that when a detached label is manually removed from the high speed rolls both sets of rolls automatically start up again, or in a manual mode that requires the operator to activate a switch to restart the detacher each time.

Abstract: A method of cutting a flat tube (6) into unit pieces, which includes moving in a transverse direction rotatable disc cutters (12) with knife edges so as to cut the upper and lower walls of a flat tube to form a pair of cutting grooves (15) and fixing the flat tube at a point upstream of the cutting groove while flexing in the vertical direction a length of the flat tube downstream of the cutting grooves to break it off at the cutting grooves, thereby providing a unit piece of a predetermined length.

Abstract: In a method of manufacturing a photoreceptor drum which has been coated and then quick dried, the drum having a plurality of vertically-stacked base drums that are coated and dried from the uppermost base drum toward a lowermost base drum.

Abstract: A device for separating sections of a perforated tubular web includes a pulling mechanism and a tearing mechanism. Each of these mechanisms has opposing rollers positioned facing each other on either side of the tubular section being separated. Continuous conveyor belts run over these rollers. The rollers of the tearing mechanism can be moved by a control element toward the tubular web. To prevent slippage of the web within the pulling mechanism when the tubular sections are being torn, the pulling mechanism is also provided with a control element which moves the rollers or cylinders of the pulling mechanism in a direction perpendicular to the tubular web in order to increase the pressure on the tubular web. The control element of the pulling mechanism is synchronized with a control element of the tearing mechanism.

Abstract: A method for breaking film perforations between a plurality of adjacent films employs an in-feed device, an out-feed device, and a festooner positioned between the in-feed device and the out-feed device. The in-feed device and the out-feed device move the plurality of adjacent films downstream through the festooner, which includes a plurality of rollers extending from a rotatable hub shaft. To perform the method, the hub shaft is first rotated to a home position. Next, a first film is fed through the festooner and into the out-feed device using the in-feed device. The out-feed device moves film downstream at a slower speed than the in-feed device. The hub shaft is then rotated at a high boost speed so that the rollers take up slack in the first film generated by the slower speed of the out-feed device relative to the in-feed device.

Abstract: A separator/folder bag machine for developing individual, folded, plastic bags. A pair of high speed separation rollers, actuated by means of a servo motor driven eccentric linkage, engages a continuous plastic web to separate individual plastic bags formed tin the web. A pair of parallel, wide belts, and a pair of similar, overlying belts, engage both sides of the separated bags and transport the bags to a plurality of folding stations. Air jets at selected locations in the folder/separator controllably direct the bags through pairs of nip rolls to fold the bags along predetermined fold lines. Sensors in the folder/separator sense abnormal conditions and deactivate particular fold stations to reject improperly formed bags. A two speed slowdown mechanism at the discharge end of the separator/folder slows the folded bags to facilitate downstream handling.

Abstract: A continuous web of material having holes and lines of perforations therein is unwound from a roll and fed onto a staging roller. From there it is pushed onto a carrier belt having pins thereon. The pins match with the holes in the web material, and the web is drawn past a fracturing station which separates sections of the web into sheets along the lines of perforations. The individual sheets then are carried by the belt around an accelerator roll which speeds up the sheets to match the speed of receiving objects with which the individual sheets are to be combined. A second staging roller is installed at the in-feed end of the apparatus and coordinated with the first staging roller, so as to provide continuous and uninterrupted feeding of the web and hence individual sheets to the receiving objects.

Abstract: Continuous business forms are detached and disposed in offset stacks. Continuous forms being fed into a conventional detacher are sensed by a first optical sensor, and after detachment are conveyed by a roller conveyor away from the detacher in a first direction. A guide rail is elongated in generally the first direction and the detached forms have an edge which engages the guide rail so that all the forms in a particular group are aligned when discharged from the conveyor into a stack. The guide rail is mounted on guide rods, for movement in opposite second and third directions, both generally perpendicular to the first direction, so as to change the position of the edge of detached forms in a subsequent group of forms so that consecutive stacks are offset from each other.

Abstract: Closure usable for dispensing tear off lengths of rolled sheet materials, including plastic trash can liners. A `roll top` door is included which incorporates in it a roller mechanism. The lower supporting body of the apparatus also has provided a roller mechanism. When the roll top door is closed, the roller on the door is brought into contact with the roller on the apparatus. When used, the door on the apparatus is opened and a store of sheet material to be dispensed is placed within the apparatus. An amount of sheet material to be dispensed is played out over the lower roller. When the door of the device is closed, the top roller is brought into contact with the upper surface of the sheet material to be dispensed. The friction between the upper and lower roller provides tension on the sheet material when sheet material is pulled from the apparatus.

Abstract: The ticket dispenser is usable to dispense a wide variety of tickets, but is particularly beneficial in dispensing lottery tickets, and other tickets stored in panels in fan-folded stacks. The leading edge of the ticket panel is thrust against a curved guide which serves as a barrier. This causes the lead ticket to bend along a perforation line and be thrust out of the outlet of the ticket dispenser at an angle to the rest of the panel. The rest of the panel is held firmly, and the ticket easily can be torn free on the perforated line along which the panel is bent. A swinging gate is provided for closing the outlet opening and swinging away to permit bending of the ticket panel, and pushing and/or guiding the ticket through the outlet opening. The dispenser is fast, simple, compact and accurate, and does not cut tickets in half, and yet does not permit strips of tickets to be pulled out of the machine by the user who has not paid for them.

The partially severed lineations are pulled apart when the strip of paper enters the oscillating mechanism.

Abstract: A method and an apparatus for severing a perforated web involves clamping the web (4) by two clamping members (6, 7) extending essentially transversely over the web (4) against an anvil (1) placed on the opposite side of the web (4) so as to leave a perforated line (5) of the web aligned between the clamping members (6,7). The clamped web is then tensioned by allowing a tensioning member (2) located between the clamping members (6,7) to expand toward a backing bight (20, 21) formed behind the web (4) thus causing the web (4) to be severed at the perforation (5) with the help of tensile stress.

Abstract: In packaging machines with an integrated apparatus for the production, storage and conveyance of blanks, the arrangement of the apparatus within the packaging machine is important. It is necessary to ensure that free unimpeded access to the units is possible. On the other hand, the actual operation of the packaging machine should not be impaired. For this purpose, a web of material (16) for the production of the blanks (13) and in the form of a wound reel (17), a conveying track (18) for the web of material (16), a severing station (19) for forming the blanks (13) and a blank track (26) for feeding the blanks (13) to a folding turret (10) are arranged on the rear side (25) of the packaging machine. The conveying track (18) for the web of material (16) extends parallel to the longitudinal mid-plane of the packaging machine. The blank track (26) follows this transversely.

Abstract: When blanks for producing (cigarette) packs are made in the region of the packaging machine itself, especially by being severed from a web of material (12), the blank production must be matched to the performance of the packaging machine. For severing blanks (10, 11) from a web of material (12) having stampings, perforations, etc. drawing rollers (25, 26) and conveying rollers (33, 34), on the one hand, and tearing rollers (27, 28 and 35, 36) running at a higher speed, on the other hand are used. The blanks (10, 11) are torn off as a result of the difference in the conveying speed. In the simultaneous processing of two blanks (10, 11), units (23) comprising two blanks (10, 11) are first servered from the web of material (12) and these are then divided into individual blanks (10, 11) which are conveyed further, especially fed to a folding turret (20).

Sensors count the passage of holes in the tractor feed strips. An interface including analog-digital and digital-analog conversion blocks cooperates with the sensors and a central processing unit to control the perforated web separator. One pair of sensors is provided to transmit and receive horizontally across the moving web to sense a web jam.

Abstract: The present invention relates to a method and apparatus for segmenting groove molded building boards. In a preferred embodiment, a sheet of groove molded board is conveyed onto a first apparatus which separates the side edge trim scrap from the board. The board then passes onto a segmenting apparatus comprising a first horizontal conveyor, an inclined conveyor, a second generally horizontal conveyor, and adjustably mounted roller assemblies. The first apparatus removes the side-edge trim scrap from the board and the second segmenting apparatus breaks the groove molded board transversely along the groove molded lines. In addition, the second apparatus separates the leading and trailing edge scrap so as to provide individual board panels which require no additional trimming. As an alternative, two segmenting conveyors can be used in tandem so as to remove all of the scrap, thereby obviating the need for the first trim-scrap removing apparatus.

Abstract: A stop mechanism for a feed roller associated with a cutter in a dispenser for flexible rolled web material has a stop lever mounted to pivot in a plane normal to a feed roller rotational axis, such lever having a slot with lift and stop flanges disposed on opposite sides of the slot, respectively. A feed wheel rotatable with the feed roller has a control tab to successively engage with the lift and stop flanges so that as the feed roller rotates by web material being pulled from the dispenser, the control tab first lifts the stop lever by means of the lift flange and then abuttingly frictionally engages with the stop flange to retain the stop lever in its lifted position and stop feed roller rotation until the frictional engagement is relieved by pulling tension on the web being terminated whereupon the lever drops until the tab can pass over the upper end of the stop flange to free the feed roller for further rotation.

Abstract: Method and apparatus for producing individual stacks of zigzag-folded material from a continuously fed length of material containing cross perforations.

The sheet separating apparatus comprises first and second conveying mechanisms spaced from each other and adapted to transfer the continuous sheet and to increase tension on the continuous sheet along the course of transfer thereof, and a guide roller for maximizing the increased tension at a predetermined position in the continuous sheet, thereby starting separation of the continuous sheet at that portion of each weakened line which corresponds to the predetermined position.

Abstract: An overhead unit used with a printer having a platen for feeding continuous, fan-folded, edge perforated forms. Tractors engage the feed perforations on the forms. The unit automatically bursts the side perforations by the use of flexural members which extract energy from the forms feed and oscillate to burst the side perforations. Bursting of the cross perforations is carried out by a pivotally mounted, lever actuated bar which engages the platen and forms a toggle therewith to engage the successive forms against the platen just below the cross perforations; the toggle being arranged to tighten and increase the clamping force, as the form is pulled away from the platen when bursting the cross perforations. A roller assembly including rollers engaging the outside of the loop on the infeed or upstream side of the platen removes any platen wave due to differential displacement of the forms as they travel with linear motion through the tractors and with rotational motion around the platen.
