Definitions

  • the invention relates to a knife for cutting disruptive fiber associations forming on textile machines with an interchangeable knife blade, the knife blade being mounted in a slide which, in a dovetail-like recess in a knife handle, moves from a working position into a protective position holding the knife blade sunk in the knife handle and back is slidably mounted.
  • winding knives are used in factories in the textile industry in which textile fibers, i.e. Both animal and vegetable as well as artificial fibers are processed, malfunctions occurring on processing machines, which can occur due to the formation of unwanted fiber coils at various points during fiber processing without being able to remedy long interruptions in operation.
  • winding is understood to mean a wound or wound fiber structure without a supporting or supporting body.
  • the winding knife shown in FIG. 1 has a C-shaped knife handle 1 with a dovetail-like recess 2, a slide 3 guided in the recess 2 in a form-fitting manner and a knife blade 4 held in the slide 3.
  • the knife blade 4 merges at its free end into a cutting head, the design of which can be seen in detail in FIGS. 4 and 5.
  • the cutting head 5 is hook-shaped and has a concave cutting edge 6, an edge 7 adjoining it obliquely and a convex outer edge 8.
  • the edges 7, 8 are, see FIG. 5, formed as non-cutting edges with optionally rounded curves and / or bevels 9 between which there is a blunt, non-cutting edge portion 10.
  • the non-cutting edge section ensures that damage to surfaces on which disruptive fiber coils can form, e.g. on rubber rollers.
  • the knife blade 4, see Fig. 1, is provided with two cutting heads 5, so that when one cutting head 5 becomes blunt, the knife blade 4 for the further Ge can only be turned.
  • the oblique edge 7 adjoining the cutting edge 6 has an angle d of 20 ° to 70 ° to the longitudinal axis 12 of the knife blade 4, preferably approximately 45 °, while the angle ⁇ of the cutting edge 6 is 25 ° to 45 °.
  • a rounding r of 1.0 to 3.0 mm can be provided.
  • the knife blade 4 is held in the slide 3 by means of a bore 11 in the knife blade 4, as will be described below with reference to FIGS. 2 and 3.
  • the slide 3 consists of two parts 3 ', 3 ", the knife blade 4 being between these two parts.
  • the part 3' has a recess 17, in the bottom 18 of which lies the part of the knife blade 4 located in the slide 3, and between whose side faces 19 the other part 3 "is embedded.
  • a clamping screw is used to clamp the knife blade 4 used with a threaded bolt 21, a rotary wheel 23 and a collar 24.
  • the threaded bolt 21 of the clamping screw is inserted through a bore 14 in part 3 ′ of the slide 3, through the bore 11 of the knife blade 4 into a threaded bore 22 in part 3 ′′, and thus the knife blade 4 is screwed in place and the slide 3 is guided in the recess 2, there is a play-free connection of the knife blade 4 with the knife handle 1.
  • the clamping screw is removed by turning the handwheel 23, whereupon the knife blade 4 can be pulled out and turned or replaced by a new knife blade.
  • the handwheel 23 is then screwed back into the threaded bore 22 and thus the fixed connection of the knife blade to the slide 3 is created.
  • a locking pin 25 is fastened in the knife handle 1 on the end face opposite the opening 13 ', on which a slot 26 arranged in the protective position of the knife blade 4 can engage, whereby the slide 3 in the protective position is held.
  • the knife blade 4 consists of steel, the knife handle 1 made of light metal or plastic and the slide 3 preferably made of plastic.
