  • Patent number: 4966054
    Abstract: This disclosure relates to a method and an apparatus for producing a punch (3) having sharp cutting edges (41) for label cutting apparatus or the like. In order that the cutting edges (41) may have a constant height and that they may be made semiautomatically, a punch body (3) is provided with a raised edge (4) in a first process step, by etching for example, and this edge is then made into a sharp cutting edge (21) in a second process step by hammering. An apparatus suitable for this purpose contains a table (2) for the punch body (3), over which tool (32, 70) in the form of a hammering and/or cutting tool and having an roof-shaped notch (34) is disposed, which can be reciprocated automatically in the direction of the table (2) between two dead centers in order to give the raised edge (4) an external contor corresponding to the roof-shaped contour of the notch (34).

  • Patent number: 4848190
    Abstract: The invention relates to an apparatus for the automatic production of a punch having a sharp cutting edge, especially for label cutting apparatus, made from a punch body provided with an upstanding land. To avoid the former manual finishing of the land produced by etching or by some other manner, a largely automatically operating apparatus is proposed which has a table (6) for the punch body, a tool (56) with a roof-shaped notch facing the table (6), a first drive (64) for the automatic movement of the tool (56) back and forth in the direction of the table (6) and additional drive (15, 37, 51, 62) for the production of relative movements between the table (6) and the tool (56), by means of which the tool (56) can be guided automatically along the land (22) (FIG. 1).
