Definitions

  • the base body 12 has the ring 41 in the circumferential direction a positive connection.
  • the edge 46 in Area of the cylindrical inner wall 44 has a recess 7 into which a projection 6 of the base body 12 engages. Projection 6 and recess 7 result thus viewed in the circumferential direction of the opening roller a positive Connection.
  • Opening rollers 1 for open-end spinning devices are used in a known manner fiber material fed to the purpose as a sliver for spinning in Dissolve individual fibers, which are then collected in a fiber collection groove and spun into a thread there. This process is known to the person skilled in the art so that it need not be explained here.
  • the opening roller according to FIGS. 6-8 contains a sleeve-like clothing ring 20, on which the dissolving of fiber material to be spun serving sawtooth or needle-like set 30 is attached. At this Set 30 is preferably made of the full material of the Set of 20 saw teeth machined out by cutting.
  • the set ring 20 opening roller 1 contains as further components a base body 40 and a clamping washer 75. During assembly, the Set ring 20 between a radially projecting ring flange 76 des Base body 40 and a similar ring flange 77 of the clamping washer 75 braced. The ring flanges 76 and 77 protrude in the radial direction Height of the set 30, so that after mounting the opening roller 1 Set 30 is largely protected against damage.
  • the bracing of the trim ring 20 is a clamping screw 78, the one the base body 40 and the spring washer 75 centering shaft 90 added becomes.
  • the opening roller 1 also contains a stationary one Bearing housing 10, of which a rolling bearing 110
  • each axial stop surface 713 and 714 of the clothing ring 20 interrupted by a circumferential annular groove 715 or 716, whereby the stop surfaces 713 and 714 thus interrupted by a recess are.
  • the ring grooves 715 and 716 now each contain one So-called positioning surface, which is described in more detail below becomes.
  • the recess formed as a circumferential annular groove 715, 716 contains circumferential cylindrical ring surfaces 717 and 718, of which that ring surface 18 with the smaller diameter as the centering surface is trained.
  • the positioning surface is therefore involved around a centering surface. Since now every frontal stop surface 713, 714 such a centering surface 718 can be assigned the cylindrical inner surface 712 of the clothing ring 20 is completely support-free stay.
  • FIG 11 shows an enlarged view of an axial section through an opening roller with a clothing ring according to the invention
  • Figure 12 shows a cross section through the opening roller along the cutting surface II - II of FIG. 11.
  • the clothing ring 20 according to the invention contains a sleeve-like clothing carrier, on which one the dissolving of fiber material to be spun serving sawtooth or needle-like set 30 is attached. At this Set 30 is preferably made of the full material of the The saw carrier is machined out of the saw teeth.
