Upon Emergence From Hollow Cutter Patents (Class 83/97)
  • Patent number: 7628103
    Abstract: An apparatus for punching and binding a stack of papers is disclosed. The apparatus includes a paper clamp and a binding element insertion device that are movable relative to each other. The binding element insertion device is configured to receive and detect binding elements of different sizes. The apparatus also includes a punching mechanism, a controller, and a user interface. The controller controls movement of the paper clamp and the binding element insertion device based on the size of the binding element needed to bind the stack of papers together. The user interface is configured to provide information to a user of the apparatus and to receive input from the user before, during, and after the punching and binding operation.

  • Patent number: 7568410
    Abstract: A method is provided for cutting beaded fabric that includes a bead attached to cloth-like material. According to one embodiment, a continuous length of the beaded fabric is fed through a guide into a die-cutting press and is die-cut via a soft anvil die while the material is retained in the guide. A guide is also provided for retaining the beaded fabric during die-cutting operations. Pre-cut beaded fabric is also provided that is easily separated into tie-downs. A continuous cutting method is also provided for forming individual tie-downs from a combination of fabric and plastic material used to form a bead on the fabric. The continuous cutting method may include die-cutting beaded fabric, placing a mark on a bead of the beaded fabric, and severing the bead at the mark.

  • Patent number: 5676032
    Abstract: A steel rule cutting die for cutting fixed patterns in a single or plurality of stacked material layers according to the shape of the steel rule. The invention provides for a decrease in the quantity of scrap material produced, by minimizing the amount of gap between adjacent cavities in the steel rule cutting die. Pre-sharpened steel rule is used with the cutting edge shifted to the outboard side of the cavity thus reducing the amount of compression or wedging of scrap material between adjacent cavities, and thus allowing adjacent cavities to be positioned closer to one another or to contact one another without reducing the ability to remove the scrap material after the cutting operation. Frayed scrap material can be evacuated through the base of the die by providing evacuation holes in the base substrate of the die as well as providing for evacuation of scrap material from marker notch locations along joined sections of adjacent cavities. A variety of cavity shapes can be accommodated.

  • Patent number: 5249492
    Abstract: Apparatus and method for severing and stacking articles which have been differentially pressure formed in a sheet of thermoplastic material from the sheet. Apparatus is provided for moving the sheet in a horizontal path and relatively vertically moving opposed upper and lower trim dies into engagement with vertically opposite sides of the sheet to trim the articles from the sheet at a trim station. The articles free fall through an opening in the lower die and free fall to an underlying accumulator. The accumulator includes mechanism which is moveable from a stack forming position in the path of freely falling articles to receive and accumulate freely falling severed articles in a stack, and a releasing position in which a formed the stack is released for vertical free fall.

  • Patent number: 4836070
    Abstract: A method and apparatus for producing fibrous web pieces by die cutting the pieces from a continuous web. In the method, a fibrous web is provided having adjacent corrugations usually filled with a powder, and the powder-filled web is passed through a matched cutting die set intermittently which cuts and punches out the individual web pieces. Following the web cut out step, the web pieces are transferred downwardly onto a shuttle conveyor, and the pieces moved forward and simultaneously spread apart to permit subsequent convenient placement of the pieces. The cutting die apparatus includes matched punch and body die units which closely interfit with less than about 0.001 inch total clearance, so as to cut and punch out the fibrous web pieces from the continuous web.

  • Patent number: 4716800
    Abstract: For reducing the refitting time of high-speed presses as a consequence of the adaptation of the distances of stacking spindle and support members to the dimensions of the cutting tool to be interchanged and of the blank, the stacking spindle and the support members are arranged on interchanging rails adapted to be displaced out of the press table. Upon reaching the required height of the stack, the spindle tip adapted to be separated from the stacking spindle is held by a retaining device consisting of adjusting means and slide member so that the stack can be lowered to the discharge conveyor plane.

  • Patent number: 4691604
    Abstract: An improved press produces oval blanks arranged in a "nested" pattern from a web of material. The press includes a cutting die plate having a plurality of oval-shaped discharge apertures, an inclined die shoe underneath the cutting die plate, and a punch for piercing a web supported on the cutting die plate to form blanks and then deposit the blanks into the inclined die shoe via the discharge apertures. Partitions divide the inclined die shoe into a plurality of blank transfer lanes. Each transfer lane connects one of the discharge apertures to a companion exit region. Guide rails are provided to guide blanks deposited into the transfer lanes toward the exit regions as the blanks fall under gravity through the inclined die shoe.

  • Patent number: 4572045
    Abstract: An automatic punching machine having a gripping/lifting attachment which grips and lifts upright punched stacks from a delivery channel, turns them and deposits them onto transfer statics for further conveyance to an automatic bundling machine. The deposited stacks are held in the transfer station by stack guides. So that the stack guides do not interfere when the swivel arm of the gripping/lifting attachment, which is arranged so as to be turnable overhead through about 180.degree., is swung into the transfer station, such are fastened to a lifting table which can be lowered out of the plane of further conveyance. Mounted on the free end of the swivel arm is a swivel head which is pivotable through about 90.degree. and which is provided with a parting knife for the dividing or separating of the stacks.

  • Patent number: 4543865
    Abstract: To permit punching of very small holes from a strip of sheet metal, for example to form a sequence of holes at the margin thereof, or to obtain small punched blanks, having diameters of a few millimeters, for example 1-2 mm or even less, and prevent adhesion of the punched blanks to a reciprocating punch plunger (1), the punch die (4) is formed with a shallow groove (8) in the wall of the opening (5) of a die, the groove extending either spirally or axially for the depth of penetration or stroke of the punch plunger. Upon withdrawal of the plunger, a small projection or nose which will have formed in the region of the groove will wedge or jam therein, thus preventing upward travel of the blank with the withdrawing reciprocating tool. Preferably, the opening is slightly conical, with a cone angle of, for example, about 1/2.degree. with respect to the axis (12) of the bore (5); a suitable angle of inclination for a spiral groove is, for example, 12.degree.

    Abstract: Punching press apparatus including an exchangeable tool set having upper and lower punching tools movable toward one another by a pressing ram to punch parts from sheet metal material. A stacking duct extends vertically downwardly from thepunching dies to accommodate a plurality of the punched out parts, which parts are then conveyed by endless magnetic conveyor belts arranged below the stacking duct, to remote part stacking mandrels and the like. In order to accommodate exchange of the punching tools without disconnection or emptying of the stacking ducts, the stacking ducts extend downardly to a position spaced upwardly of a press table supporting a toolholding plate, which toolholding plate supports the lower punching tool. The stacking ducts are formed as inserts in the toolholding plate so that a very simple exchange of the punching tools and toolholding plates can be effected by lateral movement of the units including the toolholding plate and punching tool out of the press ram working area.
