Cutting And Bending Patents (Class 59/75)
  • Patent number: 7966799
    Abstract: A method of manufacturing staples including the steps of placing a deformable member into a mold block and overmolding a crown onto the deformable member. In various embodiments, several deformable members may be produced from an elongate wire where the deformable members can be connected by portions of the wire. In at least one such embodiment, the elongate member can then be cut to separate the deformable members to form a plurality of surgical staples or strips of surgical staples.

  • Patent number: 6931830
    Abstract: A method for making a wire package for use as staples or brads is recited as forming a plurality of round wires, forming a plurality of flattened bonding sides on each wire to prepare even bonding surfaces on each wire and bonding each wire to an adjacent wire by adhering the surfaces of each wire. Each staple includes two or more flat surfaces to improve the bonding strength of each staple.

  • Patent number: 6192297
    Abstract: A method for moving metal sheets of a working area by an antropomorphous robot comprises a) taking of preselected fixed input data that identify the geometry in the space of components of a working island; b) taking, comprising from a machine tool, preselected variable input data comprising dimensions and shape of a preselected metal sheet to be handled and a sequence of working preselected metal sheets; c) processing the fixed and variable input data on a processing unit in order to generate automatically output data that identify a preselected trajectory of the metal sheet to be handled and d) transfer the output data to a control unit of the robot in order to drive said robot to move the metal sheet along the preselected trajectory so as to handle said metal sheets selected by type.

  • Patent number: 5938388
    Abstract: A staple wire supply roll is positioned on a threading-in device that can be moved out of a stapling apparatus, and the leading end of the wire is transported by means of a thread-in transport device, through a flexible guide tube, to a stapling device. A sensor positioned on the stapling device signals the end of the threading-in operation when the leading end of the staple wire passes by. By pushing the threading-in device into the apparatus, the staple wire transport device of the stapling device is set in motion, as a result of which the leading end of the staple wire is transported to a location which positions the leading end of the wire in device. The staple wire is transported, in accordance with the thickness of the sheet stack measured by a sensor, by a stepping motor, which at the same time drives a radial cam unit.

  • Patent number: 5404707
    Abstract: A fastening element is constructed from a first bar-shaped member (12), wherein a second bar-shaped member (14a ) and a third bar-shaped member (14b ) extend in parallel along a direction normal to the axial direction of the first bar-shaped member (12). The first bar-shaped member (12) has respective ends in which flat or bent slanted portions (18a, 18b ) are formed. The first bar-shaped member is formed additionally with first and second ribs (20a, 20b ) which extend outwardly beyond respective connecting positions between the first bar-shaped member and the second and third bar-shaped members (14a, 14b.

  • Patent number: 5381649
    Abstract: A medical staple forming die and pusher punch for use in a staple forming machine. The bend radius of the staple is formed either by the form punch pushing the wire past a set of rollers, or by movable forming dies in conjunction with a tapered or contoured pusher punch. Since the wire is not scrapping on a stationary rail, pulling thin or cracking in its corners is substantially eliminated and the possibility of metal slivers produced by the prior art scrapping methods is substantially reduced or eliminated.

  • Patent number: 5303539
    Abstract: A flat clip or staple is manufactured from a continuous strip of flat sheet material in coil form by first stamping out intermediate portions of material between each of the blanks to be formed into a discrete staple while retaining the blanks in the continuous strip. The strip is then subjected to a second stamping process where each discrete staple is severed from the strip, formed into the required shape and the excess waste material removed from the continuous strip. The second stamping process is located immediately adjacent the final stapling assembly operation, such that the staples never need to be transported to the final stapling operation site in separated form.

  • Patent number: 5035040
    Abstract: A hog ring fastener has a straight line base and legs each perpendicular to the base but offset at an angle to each other permitting the use of relatively inexpensive "C" points. A stick of the fasteners is generally channel shaped, with the legs and bases all angularly inclined to the longitudinal axis of the stick. The assembly of fasteners is made in a multiwire process by severing blanks and forming the legs at a bias to a line perpendicular to the wire direction. A tool and method for applying the fastener carries out two different deformation stages, one being a predeformation stage to incline the legs of the fastener inward to a preferred application position.

  • Patent number: 4066165
    Abstract: Novel glue-less staples are formed economically of sheet metal having essentially abutting but parted margins, the staples being joined to one another by localized integral connections along the margins. The connections can be of controlled size and their weakness can be controlled by mechanical working of the metal. As a specific feature, the connections can be formed to provide the standard bond strength found in glued rows of staples, so that the novel strips of staples can be made for use in conventional tackers and staplers.
