  • Said shafts are driven in an oscillating manner so that the wire-like cutting tool performs a corresponding oscillating cutting movement.
  • the amplitude of the oscillating cutting movement is smaller than the corresponding dimension of the starting shaped body in the direction corresponding to the cutting movement, so that most of the cut or waste material produced during cutting, that is to say in particular in the central region of the starting shaped body is not transported out of this.
  • the invention has for its object to provide a method of the type mentioned, in which the above-described deficiencies are eliminated in a simple manner.
  • This object is achieved according to the invention in a method of the type mentioned at the outset by using a wire-like cutting tool with a length which is several times greater than the dimension of the starting shaped body in the direction of the cutting movement, the wire-like cutting tool being used during the cutting process constant cutting speed is unwound from a first storage device and is wound onto a second storage device.

  • a clean cut through the original molded body, i.e. Clean cut surfaces on adjacent end moldings are achieved if, when carrying out the method according to the invention, the wire-like cutting tool is cleaned during the cutting process by means of at least one cleaning device.
  • This at least one cleaning device can be a cleaning brush which performs a relative movement with respect to the wire-like cutting tool.
  • the wire-like cutting tool is guided by means of guide devices provided in the vicinity of the starting shaped body.
  • These guide devices can be rollers or roller pairs, on or between which the wire-like cutting tool lies in a defined manner.
  • Said guide devices can also be formed by bodies through which guide holes extend through which the wire-like cutting tool is passed.

Abstract

Le procédé décrit sert à découper un corps moulé initial (10) ayant une dureté et une plasticité déterminées en une pluralité de corps moulés finis (24) au moyen d'un outil à fil de coupe (20) qui effectue pendant le découpage un mouvement d'avancement (v2) par rapport au corps moulé initial (10) et un mouvement de découpage (v1) dans une direction au moins approximativement perpendiculaire à la direction d'avancement (v2). Les mouvements d'avancement et de découpage (v2, v1) déterminent le plan correspondant de séparation (18, 22) entre des corps moulés finis adjacents (24) dans le corps moulé initial (10). On utilise un outil à fil de coupe (20) d'une longueur (L) plusieurs fois supérieure à la dimension (b) du corps moulé initial (10) dans la direction du mouvement de découpage (v1). Pendant le découpage, le fil de coupe (20) se déroule d'un premier dispositif d'alimentation à une vitesse constante de découpage (v1) et s'enroule sur un deuxième dispositif d'alimentation (32).
