Definitions

  • the invention relates to wipers for shredder cutting units according to the preamble of the main claim and is based on the prior art in this case of a wiper system according to DE-PS 31 12 838 by the same applicant.
  • the object of the present invention is to further simplify the construction of a cutting mechanism of the type known from DE-PS 31 12 838, as well as to make it more compact and lighter with the same performance, and the function of To improve the material intake and the wiping effect during roll forward and return.
  • the drawing largely shows schematically the cross section of a cutting unit with the new wiper design.
  • the cutting mechanism shown consists in its basic structure known from DE-PS 31 12 838 first of all from the core pieces 1 and 2 of the cutting rollers with the disk-like cutting blades 1a and 2a and the approximately half-shell-shaped scrapers 3 and 4 comprising the respective roller cores 1 and 2.
  • scraper head parts (3b, 4b) of each scraper pair 3, 4 form a preferably parallel conveyor gap "Fsp" up to approximately the mutually facing inner limits "K" of the roll core 1 and 2 extend and the scraper head parts 3b, 4b following their area running in the conveyor gap "Fsp” with at least one nose 7 protruding from the peripheral cutting disks 1a, 2a and a nose 7 running thereon and in the direction of the respective foot part 3a, 4b Groove 8 are provided, which extends with a preferably curved course again into the interior of the cutting disk circumference 1a, 2a.
  • this configuration prevents the occurrence of excessive compressive forces on the wiper head parts 3b, 4b on the exit side of the cut material and, on the other hand, results in a good wiping function with roll return for this material. It is also important for this that the depth "T" of the groove 8 is at least the same, but better deeper than that of the transverse grooves (not shown) of the cutting disks 1a, 2a. Ultimately, the additional feed or feed roller for crumpled paper or the like which has always been required in the prior art.
