Abstract: A hand-operated coil stapler includes a main body having a linkage system provided therein; a staple driving mechanism assembled to a front end of the main body and including a complex staple driver; a pusher and magazine assembly connected to a bottom of the main body and including a push rod having a staple-pushing spring fitted therearound; and a coil staple unit formed of bar-shaped staples. When the main body is downward pushed, the linkage system brings the complex staple driver to bend and drive a first staple of the coil staple unit into a workpiece. Meanwhile, the complex staple driver comes into contact with the push rod and forces the latter backward to compress the staple-pushing spring. When the main body is released, the staple-pushing spring elastically moves the push rod forward, bringing a subsequent staple to a position below the complex staple driver for a next stapling operation.

Abstract: A stapler is provided with: a forming plate (2) configured to form a straight staple (S) into U-shape; a pusher (11) configured to push the formed U-shape staple (S1) in a first direction (Df) toward a driving portion (15); a driver plate (1) configured to drive the staple (S1) within the driving portion (15) toward sheets of paper (P); an engaging portion (27) formed on the forming plate (2); and a receiving portion (20) formed on the pusher (11). The engage portion (27) is configured to engage with the receiving portion (20), during a driving operation of the driver plate (1), so as to prevent the pusher (11) from moving in a second direction (Dr) which is opposite to the first direction (Df).

Abstract: Staple forming arrangement (11) forming part of a stapler (1) in which a workpiece (6), primarily a sheaf of papers, is stapled together. The arrangement includes a bending punch (15), which is driven by a drive mechanism (12,13) and which bends elongated staple blanks (8) over a bending cushion (15). The staple blanks, which are stored in a magazine (7) in the stapler and are fed to the bending cushion by an integral feeding device (14), are bent essentially into a U-shape having a crown (24) and a first leg (25) and a second leg (26), respectively and whereupon the bending punch is withdrawn from the bent staple by the drive mechanism. After the withdrawal of the bending punch from the bent staple, the bent staple is fed by the feeding device to a staple guide channel (27) in which the staple is driven by a drive blade (17) incorporated in the stapler into the multi-piece workpiece in order to staple the pieces together.

Abstract: A staple-former (11) in a stapler (1) that uses a driver blade (10) to drive staples (17), preferably into a sheaf of paper (16). The stapler contains a magazine (7) of staple blanks (8). A feed device (6) advances staple blanks onto an integral bending die (15) for bending into staple shape. Each staple has a first and a second leg (18, 19) and a crown portion (20). The staple-former (11) includes first and second leg-bending parts (24, 26) and crown-forming part (28). A staple forms when a drive device (12, 13, 14), moves the leg-bending parts (24, 26) and the crown-forming part over the bending die (15) causing a staple blank (8) to assume a staple shape. The staple-former then reciprocates to its starting positions, the staple advances to the driver blade (10), and a biasing element (32) urges the crown-forming part (28) away from the staple-former (11).

Abstract: A stapler comprises a stapler head which accommodates a strip of wire staple blanks and is pivotable between a starting position and a working position, in which it is applied against a sheaf of papers. A staple shaper shapes the blanks into substantially U-shaped staples, and a staple driver releases the thus-formed staples from the strip and drives them one by one into the sheaf of papers. A pivotable operating device reciprocates the staple shaper and the staple driver. A drive device is adapted to pivot the operating device in such a manner that it causes the staple driver to drive a staple into the sheaf of papers in a driving stroke and causes the staple shaper to shape the following staple in a shaping stroke, as well as adapted to pivot the stapler head to its working position before the staple driver performs the driving stroke and retain it there during the driving stroke of the staple driver.

Abstract: An apparatus for stapling printed sheets includes a conveying apparatus having a plurality of sequentially spaced, saddle-shaped supports. The printed sheets straddle the sequentially spaced supports. A shaping body is rotatingly disposed on a first axis, and receives and conveys a wire segment. A stapling head holder is rotatingly driven about a second axis parallel to the first axis. At least one stapling head is radially displaceably seated in a guide arrangement on the stapling head holder. The stapling head has a bending apparatus having an end with an opening forming a guide. The opening is penetrated by the shaping body for receiving the wire segment from the shaping body, and shaping the wire segment into a staple. The stapling head further has a driver that forces the staple through the printed sheets positioned on the supports. The driver and the staple are guided by the guide formed by the opening of the bending apparatus.

Abstract: An apparatus for forming and driving staples in a single stroke includes a former for forming staples from pre-cut lengths of staple wires, a forming block around which each staple wire is bent by the former, and a driver for driving each formed staple into a workpiece. A removable cartridge (1) for containing a supply of staple wires comprises a housing (53) for the supply of wires and a staple wire delivery portion (2) through which staple wires are delivered for use. The delivery portion (2) of the cartridge has formed on it the forming block (61) for the apparatus. This arrangement provides a fresh forming block for the apparatus each time the cartridge is replaced.

Abstract: A stapling apparatus using continuous staple wire for stapling a set of sheets includes a stapler head having a cover thereto that partially and advantageously defines the stapel wire path therein so as to substantially reduce staple wire jams and misfeeds.

Abstract: A surgical instrument comprises an elongated body having a working zone at a distal end thereof. Kinematically connected between themselves and disposed within the body are: a mechanism for feeding wire into the working zone of the body, a mechanism for forming U-shaped staples from the wire, and a mechanism for reshaping U-shaped staples into rectangular ones, provided with a driver and anvils. The driver is connected with a reciprocating drive along the longitudinal axis of the body and is provided with a working portion in the form of two V-shaped projections. The anvil is disposed in the working zone of the body perpendicularly to its longitudinal axis in a plane of motion of the driver so that it can be moved out of this plane. The length of the anvil is less than the transverse side of the U-shaped staple.

Abstract: Electrical components are processed faster and more reliably with an improved centering device. In one embodiment, thread slack is provided in the relatively slow adjuster used to preset a component processing machine to a particular insertion span, and a faster acting adjuster makes use of this thread slack to vary the preset span and center the component body in the machine.

Abstract: A wire stitcher in which a piece of wire is cut from a supply of wire W fed to a stitcher head and formed and driven through a set of sheets to bind the sheets together. The wire is guided into position relative to the driver and former by a guide mechanism arranged in the path of the former and which is resiliently mounted so as to be displaced by the former during forming.

Abstract: A wire stitcher for binding sheets into sets in which cut lengths of wire are formed into staples about an anvil by a former and the formed staples are driven by a driver. The wire is gripped against the anvil by the driver during forming and the staple is supported with the aid of the anvil during driving. The driver has a two-stage action in which a first stage motion operates to grip the wire against the anvil during forming, the driver motion being arrested during forming, and a second stage motion acts following forming to effect driving. The movement of the driver and the former is effected by a continuous travel of an input lever.
