Abstract: A punch change retainer for positioning a floating punch in a retracted, disengage position and an extended, engage position. The change retainer includes a change retainer body and a punch retainer receiving aperture extending upwardly through the change retainer body from a bottom surface thereof. A gagging member is located in the change retainer body and is actuable by an actuator between a retracted position distal from a nose portion of the change retainer body and an extended position adjacent the nose portion of the change retainer body. A floating punch retainer is receivable within the punch retainer receiving aperture, and includes an upper end positioned for engagement with the gagging member. A punch receiving hole is defined in the floating punch retainer; where the punch receiving hole is adapted to be rotatably positioned about a longitudinal center line of the floating punch retainer within the punch retainer receiving aperture.

Abstract: A cutting apparatus of blade's raw material used in a paper blanking die for manufacturing paper box and the like and an automatic cutting system using this cutting apparatus. This cutting apparatus comprises: cutters more than two kinds having different cutting out or cutting off patterns arranged side by side laterally against a feeding direction of the blade's raw material; a cutter guiding section for guiding said each cutter so as to be able to perpendicularly move against a plane of said blade's raw material; a pressing means for perpendicularly moving and pressing any one of the cutters toward a plane of said blade's raw material; a cutter die for supporting said blade's raw material against the pressing force of said cutter and simultaneously interacting with said cutter whereby executing the cutting work of the blade's raw material; and a cutter selecting means for selecting such that only any one of said cutters is pressed by said pressing means.

Abstract: A stamping device includes a base body; an elongated punch having a longitudinal axis; a supporting arrangement for holding the punch in the base body and for guiding the punch for axial displacements between an advanced position and a retracted position; a driving unit releasably held in the base body and including a driving device for axially displacing the punch; a coupling device having a first state in which the coupling device operatively connects the driving device with the punch and a second state in which the driving device is disconnected from the punch; and a receiving arrangement for holding the punch in a desired axial position when the coupling device is in its second state.

Abstract: An automatic change-over ball lock punch retainer including a punch retainer having a punch, a retainer block, and an arm member in a sliding engagement retainer with the retainer housing block. The arm member having a camming means which interengages with an inclined surface of the punch retainer to move a punch into an active or inactive punch position.

Abstract: The present invention relates to a cutting apparatus a used in a paper blanking die for manufacturing paper box and the like and an automatic cutting system using this cutting apparatus. This cutting apparatus comprises: more than two kinds of cutters having different cutting out or cutting off patterns arranged side by side laterally against a feeding direction of the raw material; a cutter guiding section for guiding each cutter so as to be able to perpendicularly move against a plane of the cutters toward a plane of the raw material; a cutter die for supporting raw material against the pressing force of the cutter and simultaneously interacting with the cutter whereby executing the cutting work of the raw material; and a cutter for selecting such that only any one of the cutters is pressed.

Abstract: Between a plurality of side-by-side punches and an operating slide having reciprocating motion is arranged a selective motion transmission device which consists of two pluralities of toothed couplings in mutually opposed positions. The toothed couplings of a first plurality are made integral with the punches while the others follow the reciprocating motion of the slide but are shiftable transversally to it between a neutral position and a working position. In the latter position the teeth of the opposed couplings are mutually aligned and thus allow transmission of the reciprocating motion of the slide to the corresponding punches.

Abstract: A punch holder is detachably connected to the lower end of a vertically reciprocable ram and carries a plurality of differently shaped punches which are supported to slide upwardly and downwardly in the holder. Individual actuators are operably associated with the punches and selectively activate one or more punches during any given punching stroke of the ram so that either one hole or multiple holes may be punched during such stroke.

Abstract: A punching unit in a punching binding machine for joining together packs of sheets by a resilient teeth comb binder, comprises on a framework of the machine: a fixed bar provided with openings having a substantially vertical axis; a plurality of punches, each of which extended through the openings and each comprising a bottom cutting edge and a tang extended at the top of the bar; a movable bar arranged at the top of the fixed bar and carrying a series of catches, each of which movable between an active position for operating the relative punch, and a rest position where such a punch is not thereby operated; the movable bar being supported on slides sliding on the framework; a control assembly for the lowering of the movable bar on the fixed bar.

Abstract: In a tape punching device, punching needle selection takes place by means of selector strips slidably mounted in a rocking arm and engaged by armatures of selector magnets at their rear ends in the vicinity of the rocking axis of the rocking arm. The rocking arm and selector magnets are mounted in a separate case which is insertable in a main housing containing a continuously rotatable main shaft with an eccentric engageable by an open fork at the front end of the rocking arm. The main housing also contains a feeding mechanism alternatively usable for forward feed and back-space through 180.degree. displacement of a pulse supplied to a feeding magnet.

Abstract: A compact, lightweight, manually operated voting machine with provisions for straight ticket, selective and write-in voting, and for choosing two or more candidates from a list of several running at large; with provision for recording each voter's choice on a punch card for computer counting, and including a mechanical counter automatically totalling the votes for each candidate for confirmation of the punch card count.

Abstract: A tape punch machine in which several subassemblies are arranged for accurate adjustment and easy detachment; to assure accurate and reliable tape movement a stepping motor for feeding the tape receives two pulses for each spacing increment of the tape. The punches are selected by interposers which are not released if the same punch function is to be repeated in successive cycles of the machine.

Abstract: An apparatus for swaging the movement control belts for controlling the operational groups of a knitting machine comprising a punching bar, a die, punches, a punch bearing plate, entrainment means, a movement control belt, punch selection means, and a selector keyboard.

Abstract: A machine tool comprising a frame, a plunger mounted on the frame for carrying a work engaging tool, a way in said plunger for receiving a reciprocating ram, a punch block, a linkage for selectively inserting said punch block between the ram and the plunger so as to cause the ram to drive said plunger toward a work support, a bolt mechanism carried by said ram for selective operative engagement with said plunger to pull said plunger away from said work support only after said plunger has been driven toward said work support by said ram, camming surfaces on said plunger and said bolt for selectively disengaging said bolt from said plunger upon subsequent movement of said ram toward the work support, and a single stroke mechanism in said linkage to automatically withdraw said punch block after the driving of the plunger toward the work support whereby subsequent continued reciprocation of said ram will not drive said plunger unless said linkage is again actuated.
