Definitions

  • the invention relates to a device for cutting film webs with inherently elastic circular cutting knives, which are interchangeably received in a hub flange of a knife shaft and which are axially adjusted against likewise circular slot knives, which are clamped on a slot knife shaft, the disk knives using intermediate rings on the Disc knife shaft are clamped, in which each of the cylindrical intermediate rings has on one of its outer surfaces a radial circular cylindrical groove in which one or more spring elements are inserted, the point of engagement of which lies within the radial diameter of the intermediate ring, so that the disc knife lies completely flat when the disc knife shaft is clamped and is only deformed axially by the grooving knife when it is turned on axially.
  • the disc knife is pressed against the slot knife by a spring.
  • DE 968 269 describes a circular knife which consists of a thin ring disk which is held on an annular support member.
  • the circular knife is slightly conical.
  • the circular knife is pressed against the counter knife by a helical spring. Due to the additional use of a support ring, the knife system described is very complicated in structure.
  • Document NL-A 8 503 497 describes a longitudinal cutting device in which two circular knives prestressed by springs act on both sides of the edge of the opposite slot knife.
  • the spring preload is brought about by the fact that a clamping piece provided with a radial groove is arranged on one side of the disc knife, a spring element being inserted in the groove and pressing the circular knife against the groove knife edge via a spacer disc.
  • DE-A 24 37 860 describes a circular knife receptacle in which a tension spring is arranged between a collar of the receptacle hub and the circular knife back at a distance therefrom and axially displaces the rigid circular knife provided with an anti-rotation element against the opposite knife.
  • the disc knives are rigidly clamped between spacer rings.
  • FIG. 2 The principle of this arrangement is shown in FIG. 2.
  • This arrangement is known from US Pat. Nos. 4,330,092 and 4,428,265.
  • the disc knives (1) are firmly clamped between spacer rings (9) and serve themselves as a resilient element. Since the disc knives are manufactured with tight tolerances and are made of high-quality materials, such as hard metal, the individual "springs" are very even.
  • the disc knives are deformed such that the edge of the disc knives does not touch the groove knife edge, thereby avoiding damage to the disc knife edge, which is favorable for the cutting quality.
  • the intermediate ring (33) has a radially circumferential groove (21) adjacent to its one side surface, the depth of which extends in the radial direction approximately to the inner bore of the disc knife (1).
  • a thin elastic spring ring (18) is formed, the outer open end of which is bent and with its side surface (19) presses the disc knife (1) against the next intermediate ring (33), the outside of the open end of the spring ring with the radius of the intermediate ring (33) is flush.
  • the spring ring has a recess (20) between the outer and inner end on its side facing the disc knife.

  1. Dispositif de découpe de tôles, comportant des couteaux de coupe de forme circulaire, élastiques en soi, qui sont repris dans une bride de moyeu d'un arbre à couteaux de manière à pouvoir être échangés, et qui sont agencés axialement contre des gorges de couteau, également de forme circulaire, qui sont serrées sur un arbre à gorges de couteau, les couteaux circulaires étant serrés sur l'arbre à couteaux circulaires au moyen de bagues intermédiaires, chacune des bagues intermédiaires cylindriques présentant sur une de ses surfaces externes une rainure radiale cylindrique circulaire dans laquelle se trouvent un ou plusieurs organes à ressort dont le point d'action est situé à l'intérieur du diamètre radial de la bague intermédiaire (33), de sorte que lorsque l'arbre à couteaux circulaires est à l'état serré, le couteau circulaire est entièrement plan et n'est déformé axialement par les gorges de couteau que lors de la pose axiale, caractérisé en ce que chaque bague intermédiaire (33) serrée sur l'arbre (6) à couteaux circulaires présente au voisinage de sa surface externe cylindrique une rainure (21) s'étendant radialement, dont la profondeur dans la direction radiale atteint sensiblement l'alésage intérieur du couteau circulaire (1), et en ce que l'extrémité extérieure ouverte de la mince bague de ressort (18) ainsi obtenue est repliée en direction de la bague intermédiaire (33) suivante, et repousse par sa surface latérale (19) le couteau circulaire contre la bague intermédiaire suivante, en ce que, sur son côté tourné vers le couteau circulaire, la bague de ressort présente un évidement (20) entre son extrémité extérieure et son extrémité intérieure, et en ce que la force de ressort des éléments à ressort (18) est assez grande pour que lors de la pose axiale de la gorge de couteau (2) à l'intérieur de la région dans laquelle le couteau circulaire (1) s'appuie contre la bague intermédiaire (33), le couteau circulaire (1) n'est pas déformé.
