Abstract: An apparatus for the division-true, intermittent feed of a sheet of indeterminate length has a sheet supply roll; a table for receiving the sheet from the supply roll; a sheet tensioning device disposed between the supply roll and the table; an advancing device for advancing the sheet in each operational cycle through a forward feed stroke that is greater than the divisional distance defined by spaced markings on the sheet; a cutting device for cyclically severing a length from the sheet subsequent to the forward feed stroke; a reversing device for retracting the sheet in each operational cycle through a centering stroke subsequent to the forward feed stroke.

Abstract: A web-tensioning apparatus has stationary and movable clamps for clamping the opposite ends of a length of web, the movable clamp having a first spring for elastically forcing it in a direction towards the length and a second spring for elastically forcing it in a direction away from the length, the second spring providing greater spring force than the first spring plus the clamped length's initial resistance to stretching. If the web does stretch a little, the first spring relaxes so that the second spring can exert more force to move the movable clamp away from the stretched length.

Abstract: The accurate and uniform indexing of paper business forms with line hole punched margins. The index drive overcomes any possible accumulation of errors. A pawl and ratchet device is employed in the feeding of the paper form. The ratchet is rotated approximately one-half tooth beyond the ultimate desired stop. A spring urged arm then pulls the ratchet wheel back that one-half tooth turn so the pawl rests solidly in a single ratchet tooth. It is this same spring arm that pulls back the over-fed paper form. The form pull back is permitted by reason of a magnetic one-way clutch being momentarily released at the end of the mechanical feed-out. The present device is a combination of a mechanical drive with a magnetically releasable clutch to effect a constantly accurate feed out of paper forms resulting in identical positioning of each of the series of continuous paper forms.

Abstract: A method for controlling the movement of a web of material. The web material advances in a forward direction, thus creating an unsupported loop which characterizes the festoon arrangement of the invention. Web material is advanced into the festoon depending upon the size of the festoon. Web material is withdrawn and returned to the festoon on an intermittent basis independently of the flow of material into the festoon.

Abstract: A method and apparatus for removing the coil set from a coiled roll of sheet metal material or the like, and which comprises a pair of cooperating rolls defining a nip through which the sheet metal is advanced, and a deflecting roll positioned immediately downstream of the nip to flex the advancing sheet material beyond its yield point and remove the coil set therefrom. Upon stopping of the advance to permit the cutting or other processing of the sheet material, the deflecting roll is automatically withdrawn from contact with the sheet material to thereby prevent the formation of a crease in the material, and upon restarting of the advance, the sheet material is initially reversely advanced a short distance to insure that any portion of the sheet material which has not been flexed to remove the coil set will be positioned upstream of the nip before the forward advance is commenced.

Abstract: A web is reciprocated through a treatment roll pair so that a succession of treated areas is formed on the web, one of said areas being formed on each forward movement, and the reverse movements serving to enable re-positioning of the web and avoiding waste between each two said areas. Two pairs of feed rolls are provided, one pair for forward feed and one pair for reverse feed. Each feed roll pair is engageable with and releasable from the web by having separable rolls. The feed rolls are all driven from a common camshaft.

Abstract: Apparatus for die-cutting preprinted web has an adjustable web feed mechanism which is controlled by circuitry for detecting mis-registration between die-cutting and the preprinted portions of the web, of which the following is a specification.

Abstract: A continuous textile fabric comprises a processing chamber containing a processing liquid, a squeeze roll assembly disposed above the processing chamber, and guide rolls disposed on opposite sides of the squeeze roll assembly, the textile fabric in rope-like form being introduced into the processing chamber at one end thereof and successively and spirally set toward the other end of the processing chamber so as to extend around the squeeze roll assembly and guide rolls and through the processing liquid many times and travel as the squeeze roll assembly and guide rolls are rotated.

Abstract: Method and apparatus for use in a web transport system wherein the web is stopped at a position it occupied when an event occurs. In particular, a motor driven capstan is provided to drive a web, such as a filmstrip, between first and second reels. A tachometer, operatively coupled to the capstan motor, provides a first signal representing the actual film velocity. The first signal is applied to an integrator which is controlled in a manner whereby during normal operation of the web transport system the integrator is off and does not affect system performance. When the event occurs requesting the capstan drive motor to stop, the integrator is enabled and provides an output which is proportional to the distance traveled during deceleration of the capstan drive motor (overshoot). The output of the integrator is coupled to first summing junction whereat it is added to a signal representing the desired film velocity which is driven to zero upon occurrence of the event.

Abstract: Apparatus whereby a filmstrip operator can conveniently reestablish the engagement between a sprocket and an overdriven filmstrip in a filmstrip projector. The projector operator manipulates a thumb wheel to cause a roller to come into contact with a surface portion of the filmstrip, and to cause the roller to rotate thereby causing longitudinal displacement of the filmstrip in a film track. The trailing edge of the filmstrip is displaced towards the sprocket to facilitate reengagement of the filmstrip with the sprocket.

Abstract: This application discloses an apparatus for preventing heat damage to thermoplastic web material being converted to produce bags. After a selected number of bags have been made, the web feeding rolls are automatically stopped for a short period, which may be for one or more machine cycles or stopped for an indeterminate period on command of the operator, to allow removal or transfer of a completed stack of bags. When web movement is stopped, the web feeding rolls that are driven by a belt, are rotated in a direction opposite to the feed direction to withdraw the leading edge of the web from the plane in which the heated seal bar reciprocates. Withdrawing of the web occurs by applying additional tension to that reach of the belt which will effect reverse rotation of the feeding rolls. Such additional tension is created by freely rotating pulleys mounted on a plate oscillated by an actuator.

Abstract: Method of and apparatus for electrical interconnections wherein the interconnections comprise a crimped splice connector folded upon at least one magnet wire segment, at least one filler wire segment, and at least one other wire segment including the step of and means for ensuring that the filler wire segment is devoid of major bends along its length.

Abstract: A hitch feed assembly for automatically aligning individual lead frames at a bonding site in both the longitudinal and lateral directions is disclosed. The alignment is attained as a result of the cooperation between a plurality of chamfered pawls and the sprocket holes in the film-carrier. The pawls are chamfered along three sides in order to attain alignment in both the longitudinal and lateral directions. Significantly, the pawls come into operational contact with the sprocket holes while the lead frame film-carrier is under minimal tension so that the pressure exerted on the edges of the sprocket holes by the pawls will be minimal, thereby avoiding any deformation in the shape of the sprocket holes.

Abstract: In a method for precisely advancing a printed packaging strip provided with markings at uniformly spaced distances and which is to be cut into length portions corresponding to such distances, a sensor head being provided along the feed path of the strip to produce an indication, each time a marking reaches a predetermined location, the strip being advanced during successive operating cycles, with each cycle corresponding to the cutting of a successive length portion of the strip, precise strip advance is effected by, during each operating cycle: advancing the strip first through a predetermined distance which reliably differs from the distance between successive markings; subsequently imparting to the strip, by movement of a carrying device, a correcting movement over a distance and in a direction which brings a marking to such predetermined location and causes the sensor head to produce such indication; causing the indication produced by the sensor head to actuate a clamping mechanism to cause that mechanism

Abstract: There is described a record material feed mechanism for use in an electronic cash register for feeding a record member to a printing station wherein data is printed on print lines located on the record member during the operation of the cash register. The feed mechanism will automatically position each succeeding print line of the record member adjacent the printing station on successive printing operations of the cash register. Included in the feed mechanism are a pair of cam actuated gear segments which control the length of movement of the record member between a home position and a position adjacent the printing station in the cash register. During the feeding of the record member to the printing station, the gear segments are positioned in tandem to move the record member a predetermined length while in a feed-out operation, the segments are positioned in an overlap condition to move the record member a distance which is one print line less than the feed-in movement.
