Definitions

  • the invention relates to a letter punch lower part with a chip pan arranged on the underside of the base plate.
  • the depth of the insertion slot is not limited by a step of the embossed base plate or by the pressure blocks connected to the base plate and forming the punching guides, the stops limiting the depth of the insertion slot, for example by cutting out and bending out the base plate To form tongues.
  • Letter punches are also known in which, for different limitation of the insertion depth of the documents to be punched, stops are integrally provided on a plate delimiting the chip space, said stops are designed so that their end edges facing the punches, when they cover the chip space Plate is rotated 180 °, have a different distance from the punches.
  • the base plate 1 has edges 11 bent essentially vertically downwards, the two die cutouts 12 and the part 13 connected to the base plate 1, which forms the side cheeks of the bottom punch part provided with stamp guides.
  • the chips pan 2 has four side walls 21, 21 ', 22, 22', of which the side walls 21, 21 'have tongues 211, 211' projecting beyond the edge edges thereof. These tongues are arranged and have such a width that their distances a and b from the side walls 22 and 22 'have a different size.
  • slots are provided in the base plate 1 inside or outside the two side walls, through which the tongues 211, 211 'extend. Beads are advantageously embossed from these tongues, which additionally hold the base pan behind the chip pan.
  • the slots give the tongues an additional lateral support and are dimensioned in length so that they have the same distance b from the front or rear edge 11 of the base plate 1 which is bent downwards.
  • the chip tray it only needs to be rotated by 180 ° in order to convert the punch from an edge strip width of, for example, 11 mm for letterhead perforation to an edge strip width of, for example, 8.5 mm for ring binder perforation.
  • the base plate 3 has a shape deviating from a rectangle.
  • this chip pan apart from the two tongues 411, 411 'arranged on the side walls 41, 41', for limiting the greater insertion depth at the bottom of the chip pan two perpendicularly from these protruding stops 42 are provided for limiting the smaller insertion depth, which reach through recesses 33 in the base plate.
  • the chip pan 4 is brought up to the edges 31 of the base plate when it is put on so that these resilient stops 42 rest when the chip pan is pushed against the base plate underside in a curved state.
  • the matrix recesses 32 of the base plate 3 are relatively far forward because the chip pan is designed so that it extends the lower limit of the insertion slot to the front.
  • these can also be arranged parallel to the front edge of the punch.
