  • Publication number: 20140001225
    Abstract: Stapler (1) for using a staple (6) to staple together a workpiece (24), e.g. a sheaf of papers, by the staple being driven through the workpiece, by a driver (11) fitted in the stapler, from a staple magazine (5) to a position in which the staple legs penetrate the workpiece, which stapler comprises also a clipping arrangement (14), which moves reciprocatingly relative to the staple magazine in a defined direction (H) between a working position and a position of rest so that the clipping arrangement in the working position clips off surplus lengths of the staple legs when they have penetrated the workpiece, and a container (12) for gathering the staple leg clippings by their being conveyed via a channel (15) which runs in a defined longitudinal direction (A-A) between the clipping arrangement and the container, which channel (15) is attached pivotably to the stapler by means of a connecting device (16).

  • Patent number: 7543727
    Abstract: Circuit-breaker arrangement (32) in an indicating arrangement (33) forming part of an electrically powered stapler (1). The stapler comprises a stapling head (2) and an anvil (3). The stapling head comprises an interchangeably fitted staple cassette (5) containing staple blanks (36), and the indicating arrangement. The circuit-breaker arrangement is so positioned that it is moved by the staple cassette from a first to a second position when the staple cassette is fitted to the stapling head and when the power supply via the indicating arrangement changes. The circuit-breaker arrangement (32) comprises an input line (22) and output line (23), of which at least the input line is dimensionally stable and resiliency flexible.

  • Patent number: 7469810
    Abstract: Staple magazine (7) for mounting to a stapler (1) used to staple together a workpiece (6), primarily a sheaf of papers, the said staple magazine comprising a container (8), in which elongated staple blanks (10) in the form of a strip (11) are stored, and a staple forming arrangement (9) comprising a forming punch (19), which bends the elongated staple blanks into the shape of a staple over a forming block (48), and a drive punch (20) with which the staple blanks which have been bent into staple shape for stapling the workpiece are driven into the said workpiece, the staple blanks stored in strip form being fed by a feeder plate (51) to a forming block (48) along a feed path (44) incorporated in the container, and the forming punch and drive punch being driven in a reciprocating bending and drive movement (P) by a drive arrangement (13-16) incorporated in the stapler, the container (8) and the staple forming arrangement (9) being connected to each other by means of releasable connecting devices (22, 23, 34, 35

  • Patent number: 7021513
    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.

  • Patent number: 6986449
    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).

  • Patent number: 6769592
    Abstract: Stapling device (1) for stapling a workpiece (23), typically in the form of a sheaf of paper. The stapler (1) includes a support base (3) and a stapling unit (2) connected by a connecting piece (4) in a moveable manner. The stapling unit has a stapling magazine (6) in which staple blanks (24) are stored. A driver (7) is provided that drives the stapler so as to perform a stapling operation, and during which operation the workpiece is stapled. The support base is provided with an anvil (10) on which the workpiece is placed and against which stapling is carried out; the staple being secured in the workpiece with an orientation such that its longitudinal direction (T) is perpendicular to the longitudinal direction (L) of the stapler, whereby the connecting piece (4) extends along only one long side (21) of the stapler.

  • Patent number: 6641023
    Abstract: An anti-reversing device in the feed channel of a staple magazine containing staple blanks (ii), which magazine is accommodated in a stapler, wherein the staple blanks advance along a feed channel having channel guides (22) which support the staple blanks and wherein the supporting channel guides are equipped with stops (26) which prevent a staple blank which has advanced past the stops from moving in the direction opposite to the direction of feed.

  • Patent number: 6257477
    Abstract: A stapler for driving staples (12) into a sheaf of papers comprises two guide elements (17, 17′, 17″; 18, 18′, 18″) for internal guidance of the legs (12a) of the staple (12) during the driving of the staple into the object. Each guide element (17, 17′, 17″; 18, 18′, 18″) consists of at least two substantially identical, separate guide parts (17, 17′, 17″; 18, 18′, 18″) successively arranged seen in the driving direction of the staple (12). Each guide part (17, 17′, 17″; 18, 18′, 18″) is movable between a first position, in which it extends into the driving path of the staple (12) to abut against the inside of the respective leg (12a) during the driving of the staple, and a second position, in which it is removed against spring action from the driving path of the staple (12).
