  • a punching apparatus is characterized in that said tubular member is manufactured from a sintered carbide alloy with an internal cavity in which at least the wall surfaces at the cutting edge are ground to smoothness and are perpendicular to the plane of-the cutting edge, whereas grinding of the cutting edge to a prescribed sharpness and cutting angle is performed solely on the external side of the tubular member.
  • said carbide alloy is a tungsten-cobalt alloy, which is ground on said wall surfaces to a surface roughness of Ra, a ⁇ , 0.1 ⁇ .
  • the invention is based upon the recognition of the fact that in the manufacture of the punching die it is possible to grind the wall surfaces of the internal cavi ⁇ ty which are perpendicular to the cutting edge to such a smoothness that a low friction is obtained which allows design of the internal cavity with a constant cross- section matching the punched items on a considerable portion of its length measured from the cutting edge.
  • a preferred embodiment of the punching apparatus is characterized in that said internal cavity comprises a portion adjacent said cutting edge the wall surfaces of which match the shape of said items and a succeeding portion having in- creased cross-sectional area.
  • Figure 1 schematically shows an embodiment of a punching apparatus according to the invention
  • Figure 2 is a longitudinal sectional view of a punching die in the embodiment shown in Figure 1;
  • Figure 3 shows the punching die in Figure 2 viewed in the direction towards the cutting edge.
  • the starting material is a stack or a pile 1 comprising a large number of usually rectangular sheet sections each having an individual label print. Such sheet sections which are not shown in the drawing have been produced in a preceeding operation from a printed
  • OMPI sheet comprising a large number of label prints position ⁇ ed side by side by cutting said sheets along straight cutting lines.
  • each of the individual sheet sections carries a label print having a well-defined position relative to the cut edges of the sheet section is supplied by means of a guide member 2 onto a support ⁇ ing plate in the form of a hydraulically or pneumatically operated pressure plate 3 positioned below the punching die 4 in parallel relationship to the plane comprising the cutting edge of the printing cutter.

Abstract

Un appareil de poinçonnage permettant de poinçonner des articles ayant des bords incurvés ou arqués, composés d'un matériau en feuille, en particulier des étiquettes et autres articles imprimés, comprend un poinçon sous la forme d'un organe essentiellement tubulaire (6) fabriqué à partir d'un alliage en carbure fritté et ayant une cavité inférieure dans laquelle au moins des surfaces des parois (8) du bord tranchant sont écachées, de préférence jusqu'à obtenir une rugosité de surface Ra < 0,1mu, et sont perpendiculaires aux plans du bord tranchant, tandis que le meulage du bord tranchant (7), pour lui donner une acuité et un angle de coupe prédéterminé, s'effectue uniquement sur le côté extérieur de l'organe tubulaire (6). Les intervalles entre les meulages nécessaires du bord tranchant (7) sont allongés et un nombre illimité d'aiguisages à la meule est possible tout en conservant entièrement la précision de la mesure du bord de coupe.
