Abstract: A pneumatically operated feeder for punch presses and the like and having a feed slide that is adapted to be moved automatically through successive feed and index strokes. Instead of using a limit switch type device for sensing for the physical presence of the feed slide when the latter has reached the end of an operative stroke thereof, an improved control means is provided to identify the completion of such an operative stroke and to thereby cause said feed slide automatically to initiate its next operative stroke. When pressure fluid is applied to the main fluid motor of the feeder in order to produce say an index stroke of the feed slide the effective fluid pressure in said motor will not normally reach line pressure until after completion of said index stroke.

Abstract: A solenoid clutch mechanism for providing intermittent rotation of a feed roller in a web feeding apparatus. The clutch mechanism includes a solenoid having a reciprocable plunger connected to a pivotable arm in abutment with a cam mounted on a driven shaft. The driven shaft is drivingly connected to the cam by means of an overcenter coil spring. Coupled to the cam is a gear train in driving relation to the feed roller. The driven shaft will rotate relative to the cam as long as the arm is in abutment with the cam. Upon retraction of the solenoid plunger the arm is raised permitting the cam to rotate by virtue of the spring drive connection to the driven shaft in turn causing rotation of the gear train to drive the feed roller to advance a web.

Abstract: A shared document feed station includes a common drive mechanism for normally advancing a receipt tape through a receipt tape zone and for selective operation to advance an alternative document through an alternative document zone. Document detectors sense the presence of a document in the alternative document zone and function to inhibit the drive mechanism from advancing the receipt tape while enabling the advance of the alternative document.

Abstract: A dual slide pneumatic feeder for intermittently advancing stock into the work station of a punch press or the like wherein the fluid motors of the feeder are controlled by a fluid valve means that is adapted to be intermittently driven by a ratchet mechanism. The ratchet mechanism is adapted to be actuated from two different control points; first from a trigger means that is operable in response to the movement of the press ram, and secondly from a means operable in response to the completion of a feed stroke of one or both of the two feed slides. In this control environment the two feed slides may be made to execute a plurality of consecutive feed strokes in response to each cycle of operation of said press.

The apparatus of performing the disclosed method comprises a plurality of gripping means for retaining the wire, each including a plate apertured for passage of the wire and a spring accommodated between a housing and the plate, the plate of one of the gripping means being mounted for reciprocation in the direction of feeding the wire toward the welding zone and having its side surface adapted to cooperate with an actuator mounted on the output shaft of the drive effecting the feed and transverse oscillations of the wire advanced toward the welding zone.

Abstract: An improved control system for a dual slide type stock feeder for punch presses and the like, said control system being adapted to cause the feeder to execute two serial feed strokes in response to each cyclic operation of the punch press. The control system comprises a control plunger which is responsive to the movement of the press ram and which is adapted to actuate a fluid control circuit that causes one of said feed slides to execute a feed stroke and then causes the other feed slide to execute a feed stroke; there being two serial stock feed strokes produced for each cyclic operation of said control plunger. The feed slides may be controlled so as to operate in a substantially 180 degree mutual phase relation, or each may automatically complete an index stroke immediately after completing a feed stroke so that both of said feed slides are normally disposed in indexed positions.

Abstract: For the purpose of advancing a rod, wire or the like, particularly a welding filler wire from a magazine to a welding site, the apparatus of the invention comprises at least two tappets, reciprocated by a rotary swash plate, the tappets being arranged with their axes parallel to the axis of the wire or the like and each carrying a transverse member defined by an engagement element and a clamping element between which the wire or the like is clamped when the member moves in one direction (whereby the wire or the like is advanced in that direction) whilst the member on the other tappet, moving in the opposite direction, slides over the wire or the like without the latter being clamped between the engagement element and the clamping element of that other member.

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: A web-feeding mechanism for a compact printer which can feed at least one web of paper at selectively variable feeding rates is provided. A pair of rotatably driven web feeding rollers is positioned on a first side of the web of paper to be fed, and cooperates with a pair of selectively displaceable idler rollers correspondingly positioned on the other side of the web. The respective feeding rollers are each capable of being driven at a different rotary speed. The respective idler rollers are selectively displaceable between a first position out of engagement with its associated web feeding roller, at which time web feeding by the feeding roller corresponding thereto is prevented, and a second position in engagement with the paper web and the web feeding roller corresponding thereto for feeding the web therebetween at the feeding rate of the feeding roller.

Abstract: The apparatus and method of this invention pertains to a web film advance in which a film advancing roll is carried on a frame moved by a reciprocating pitman arm. This arm is adjustable as to its stroke or travel so that a corresponding travel of the frame is also selectively adjustable. The film advancing roll is carried by a shaft mounted in bearings and is prevented from turning in one direction by a one-way clutch apparatus. This clutch allows the roll to be rotated only when the frame and roll are moved rearwardly. During this film feeding advance by the roller a rotation of the roller is achieved by a roller chain and a sprocket or a timing belt and toothed pulley. This chain or belt may be moved a small amount in response to an electrical signal to bring the web of film or paper into registration in accordance with mark indicia. Bags or simply formed, filled and sealed packages may be made by and on this simplified yet highly reliable film advancing apparatus.
