At the item attachment edge, perpendicular transversal of a corner or edge of the base causes one set of the interdigitated fingers to open, while at least one interdigitated tab finger opened at the item advancement station clears the back edge of the retainer.

Abstract: An apparatus and method for reducing or preventing fiber entry whip as the loose end of a fiber being wound on a spool enters a fiber winding device. A fiber winding device comprises a spool winder entrance, a winding spool and a fiber whip shield substantially surrounding the winding spool. A fiber entry whip reducer positioned in front of the fiber winding device comprises at least one pulley and a guide channel including a straight entry section and a curved section leading to the fiber winding device. The guide channel is formed and positioned such that the loose end of the fiber is maintained against the guide channel by centrifugal force imparted onto the fiber by the curvature of the channel and forward motion of the fiber produced by the rotating spool, thereby producing a trajectory such that the loose end of the fiber enters the fiber winding device and is maintained against the whip shield.

Abstract: A structure is disclosed primarily but not exclusively as a supplement to an existing printer or typewriter or the like, which structure includes a clamping shaft, either for clamping endless sheet stock against the traction device for the stock, or against an added on anvil bar or both.

Abstract: The disclosure concerns a label strip inserting device for use in a label printing machine of the type in which a tape-like label strip is carried between a label feed wheel and a label depressing member. The label strip inserting device comprises a platen, which is pivotally secured to the machine body of the label printing machine. An actuating member is interlocked with the platen and is pivoted thereby. A label depressing member is interlocked with the actuating member and it has a label depressing surface to drive the label strip toward the outer surface of the label feed wheel. There are links, which are interlocked with both the platen and the label depressing member. The label inserting device is constructed so that, when a tape-like label strip is to be inserted into the machine body, the platen may be turned to a full open position to separate the label depressing member from the surface of the label feed wheel, thereby forming a large guide passage for insertion of the label strip.

Abstract: A perforated form band is introduced into a form printer through an input passage or shaft. The passage is formed by spaced walls and is pivotally mounted on the printer for movement between an input position and a working position. In the input position, a form band is introduced into and aligned within the input passage. In one embodiment, the leading end of the form band contacts transversely extending stop surfaces, while in another the leading end of the form band is aligned with an indicating mark and the perforations on the form band engage with projections in the input passage. With the form band aligned, the input passage is moved into the working position engaging the perforations in the form band on pins projecting outwardly from sprocket wheels which drive the form band through the printer. In the working position of the input passage, the form band no longer contacts the stop surfaces or engages the projections used in the aligning operation.

Abstract: A label strip inserting device for use in a label printing machine; the inserting device comprises: a platen pivotally secured to the machine frame, a label guide member pivotally secured to the frame, an operating member interlocked with the platen and the guide member; rotation of the operating member moves the platen and guide member between widely spaced inoperative positions enabling insertion of a label strip and closely spaced operative positions; the operating member has a guide surface that is rotated to define part of the label strip pathway when the guide member is in its inoperative position; label guide pieces on the machine frame positioned near a label holder on the frame; the guide member aligns with the guide pieces to define an insertion pathway when the guide member is in the inoperative position.

Abstract: A device for moving a path of a moving data carrier toward and away from a surface area of a sub-carrier characterized by two pivotal support members which are mounted to pivot about respective pivot points and are pivotable between a first or forward position with a data carrier disposed closely adjacent the surface area of the sub-carrier and a second or outward position with the data carrier spaced from the suface area of the sub-carrier. The pivotal support members each have a first engaging zone and a second engaging zone and are symmetrically disposed relative to a center of the contact area so that the data carrier is in continual engagement with all of the engaging zone and maintained under a constant tension regardless of the position of the support members.

Abstract: A stamp dispensing mechanism has a cylindrical feed wheel, with axially-parallel rows of projections, rotatably mounted on a front portion of a vertical support plate that is constructed to rotatably support a roll of stamps on its rear portion. A Geneva star wheel, rotatably mounted on the plate, is operatively connected to the feed wheel for its step movement with the star wheel. A Geneva driver assembly, rotatably mounted on the plate, has a driver pin on an arm rotated by a motor also mounted on the plate. During one rotation of the arm, the pin moves into and out of a slot of the star wheel for its step movement. An arcuate part of the arm is in a recess in the periphery of a tooth of the star wheel, when the pin is not in the slot, to lock that wheel.

Abstract: A guiding and threading device for automatic pitch-adapted threading of data carriers such as punched tape. The device includes a base member having a tape support surface thereon, a feed wheel carried by the base member with a portion projecting above the support surface, a first pivotable member carried by the base member having a guiding surface positioned above the support surface and a second pivotable member opposed to the first pivotable member and having a guiding surface positioned above the support surface, the guide surfaces forming a tape receiving channel between the pivotable members and the support surface when the pivotable members are at an open position. The guide surface of the first pivotable member urges the tape into contact with the feed wheel when in a closed position.

Each of the chute assemblies includes complementarily, predeterminedly shaped upper and lower walls forming channels therebetween. The lower walls of the chute assemblies are fixedly mounted. The upper wall of the upper chute assembly is mounted for pivotal movement on extension arms which permit the movement of the upper wall away from the lower wall for easy threading of the web thereinto.

Abstract: To facilitate the introduction of running yarns into injector nozzles the cross section of the inlet openings of the said nozzles are enlarged before the yarns are laid in, the yarns are sucked into the enlarged openings and subsequently the openings are reduced to their initial dimensions. The injector nozzles are preferably used in jet stufferbox texturizing processes or with suction guns. Without special threading aids, yarns and threads supplied at high speed are sucked in automatically and conveyed into spaces under elevated pressure.

Abstract: A chart recorder has a drawer containing a supply of chart paper fed to the chart marking area, and an accumulation of marked chart paper received from the chart marking area. A flexible curved guide is connected to the drawer and to a permanent fixed guide and assumes different configurations when the drawer is moved from the chart accumulating position during a recording mode of operation, to a chart loading position when the drawer is moved to position for removing an accumulation of marked chart paper and installing and threading a new supply of chart paper during the chart threading mode. The configuration of the flexible guide aids in threading paper onto a drive roll during the threading mode, and aids in guiding the paper around obstructions and onto the roll during the recording mode.

Abstract: An improved chart carrier for a recorder permitting use with a take-up spool for relatively long periods of time, and without the take-up spool for shorter periods of time, a cylindrical enclosure being employed for rolling and enclosedly retaining the used portion of the chart in a predetermined portion of the chart carrier.
