Definitions

  • the invention relates to a letter punch with two parts articulated in the region of their longitudinal edges for simultaneous punching of documents at two points by means of two circular-cylindrical cutting edges and matrices interacting with them, the two punch parts having the same shape and each part having a recess and acting as a die has a circular cylindrical cutting edge interacting with the die of the other part.
  • a letter punch of this type is known (DE-A 2 000 263), in which all parts of the punch that occur in pairs are designed identically among themselves.
  • the known punch consists of a large number of different parts which can be produced independently of one another and which require a considerable outlay in terms of production technology.
  • the invention has for its object to improve a punch hole punch of the type specified, in particular a punch hole punch of small dimensions, in such a way that it consists exclusively of two identical parts that can be produced with one tool and are easy to assemble.
  • the letter punch consists of the two parts 1 and 2, which have a twice Z-shaped profile, so that the two edge strips 15 and 16 or 25 and 26 lie in one plane and the middle part 17 and 27 in a plane parallel to it lies.
  • Each of these two middle parts 17 and 27 has a recess 11 and 21 serving as a matrix and a circular cutting edge 12 and 22 produced by the drawing process.
  • bearing tabs 13, 14 and 23, 24 are bent vertically, of which one, 13 and 23 have a sleeve-shaped bearing pin and the other, 14 and 24 have a bearing eye.
  • the front edges of these bearing tabs 13, 14, 23, 24 form a stop for the documents to be punched; the bearing axis extends in the plane of the middle parts 17 and 27.
