Definitions

  • the present invention relates to a device for longitudinal cutting of material webs and / or material sheets according to the preamble of claim 1.
  • Cardboard scissors are known for longitudinal cutting, in particular paperboard sheets, which have cutting shafts extending across the machine width. On these the individual circular knives of several circular shears are fixed by means of clamping.
  • the cutting shafts are permanently drive-connected by means of a gearbox with a controllable motor. The transport of the material to be cut within the cutting unit is done by the peripheral speed of the circular blade.
  • the cutting forces are determined not only by the geometry of the individual cutting edges, but also by the intersection of the circular knives of a pair. This overlap is set by the distance of the cutting shafts. The overlap of mounted on the same cutting shaft pair
  • Circular shears can only be done jointly. This simplifies one
  • the circular shears can be arranged so close together that touch their clamps and out of the bow strips of a few
  • the space of the incoming and outgoing transport systems are strictly separated from the cutting unit.
  • the feed of the material to be cut within the cutting unit is thus carried out only by the driven circular shears.
  • the smallest possible arc length is essentially determined by the diameter of the circular blade used.
  • the cutting quality increases with increasing diameter of the circular blade due to the better guiding properties.
  • larger diameter circular knives allow a stiffer design of the
  • Cutting unit which in turn has an advantageous effect on the quality of cut.
  • Today's cardboard circular scissors always represent a compromise between good cut quality and the smallest possible arc length.

Several of these cross members 202 have guide rails of linear guides 203, which serve the circular shears 220.1, 220.2, 220.3 of the cutting device as storage. In this machine frame 200 in the direction of passage 6 in succession an import 1 1, the cutting unit with the circular shears 220.1, 220.2, 220.3 and an export 15 are attached.

  • the lower knife carrier 222 shown in Fig. 2 shows two mutually parallel linear guides 203. These linear guides 203 are arranged relative to each other at a considerable distance and rotated by 90 ° to the carrier 237.
