Definitions

  • the invention relates to a wiper for cylinders or rollers of textile machines with a holding rail, a holding part having a wiping lip, which is positively connected to the holding rail.
  • Wipers are known for cleaning rollers or for removing undesirable deposits on the rollers, such as loose fiber components, resin, honeydew and wax and other contaminants.
  • the wipers which extend over the length of the rolls, are provided with a rubber element which abuts the outer surface of the rolls via a wiping edge.
  • the rubber element is positively fastened in a rigid holding rail made of metal or the like.
  • An exemplary embodiment can be found, for example, in DE-OS 34 22 139.
  • wipers are known, the rubber element being fastened to the holding rail by vulcanization.
  • the invention is therefore based on the object of providing a scraper of the type mentioned at the outset which avoids the disadvantages of the known designs mentioned.
  • good interchangeability of the rubber element is to be ensured and the wiping effect is to be increased.
  • the holding part has a closed, hollow cross section and comprises the holding rail, viewed in cross section, the wiper lip projecting from the outer periphery of the holding part.
  • the holding part has a square cross section and the wiper lip is arranged in the extension of a side surface of the holding part and is inclined at an angle with respect to this side surface to the adjacent side surface.
  • wiper lip and holding part corresponds to the term of the rubber element used in the introduction.
  • the Wiper lip By using a closed hollow cross-section, the wiper lip being arranged in the extension of a side surface of the holding part, the Wiper lip provides good support, which always ensures that it is in contact with the outer surface of the roller.
  • the further proposal is particularly advantageous that the holding rail, viewed in the longitudinal direction, projects beyond the holding part and the cross section of the projecting sections is at least larger in a partial area than the cross section of the inner cavity of the holding part. This ensures exact lateral stabilization of the holding part after the holding part has been pulled onto the holding rail.
  • This cross-sectional difference can be achieved in a simple manner by providing the holding rail, which can be formed from a square bar, with a recess on at least one side surface over the area of the length of the holding part.
  • this holding rail can be carried out in a particularly simple and inexpensive manner.
  • Figure 1 shows a schematic side view of a drafting device 1 with two drafting areas 2, 3. Each drafting area is limited by two pairs of rollers.
  • the first warping area 2 is located between the pair of rolls 3/4 and the pair of rolls 5/6.
  • the second warp area also called main warp in practice, is located between the roller pairs 5/6 and the roller pairs 7/8.
  • the upper rollers 3, 5, 7, also called pressure rollers, are generally set in rotation by the driven lower rollers 4, 6, 8.
  • the lower rollers 4, 6, 8 have different speeds, the speed increasing from the lower roller 4 to the lower roller 8.
  • rollers 4, 6, 8 are each assigned wipers 9 on their lower lateral surface.
  • the wipers 9 consist of a holding rail 10, over which a holding part 11 is pushed.
  • a wiping lip 12 is arranged on the holding part 11 and bears on the lateral surface 13 of the lower rollers 4, 6, 8.
  • the scraper is attached to the machine frame 14 at both ends by means of a fastening element 15 (FIG. 6, FIG. 7).
  • the fastening element 15 holds the scraper 9 against one by one Spring 16 generated spring force in its installed position.
  • the spring 16 acts in the direction of the surface line 13 of the lower rollers 4, 6, 8 and always ensures a secure contact of the wiper lip 12 with the surface 13.
  • the fastening element 15 is fastened to the machine frame via a screw connection 17.
  • the holding part with the wiper lip 12 is shown in detail.
  • the wiper lip 12 protrudes at an angle a from the upper outer surface of the holding part.
  • a radius 18 is provided.
  • the holding part 11 has an inner clear width b, which corresponds to the thickness of the holding rail 10 designated by c in FIG.
  • the holding rail 10 has a thickness d which is greater than the thickness c in the region of the recess.
  • the mounting of the holding part 11 on the holding rail 10 is relatively simple.
  • the holding part including the wiper lip 11, 12 connected to it is heated to a certain temperature and thus expands slightly. This expansion is sufficient to easily push the holding part 11 into its end position over the outer profile of the holding rail 10 with the thickness d. After cooling, the holding part shrinks back to its original shape and is firmly fixed within the recess 19 of the holding rail 10.
  • either the holding part can be expanded and removed again by heating or the closed profile of the holding part 11 is cut open and removed.
  • a simple and problem-free change of the holding part on the holding rail 10 is thereby possible.
  • the holding rail 10 can thus be used and used again and again without any problems.
  • the shape of the holding rail 10 is simple and ensures on the one hand a fixation of the wiper lip or the Holding part 11, 12 in the stripping direction and on the other hand a stable side guide.
