Definitions

  • the invention relates to a method for operating a teasel according to the preamble of the claim 1.
  • the card shown in Fig. 7 consists essentially from a total of 110 drum and a plurality of card covers 120.
  • the spool 110 is essentially formed in the shape of a circular cylinder and has on its outer surface a set 112 on.
  • the carding machine is the set 112 made of individual stuck into a rubber fabric Wire hook formed. Alternatively, however, you can also drum sets in the form of the cylinder axis of the drum circular sawtooth wires are used.
  • the reel is around its Cylinder axis rotated, as indicated by arrow 114.
  • the covers 120 are on an endlessly rotating transport element 126, such as a conveyor belt or one Transport chain, attached. With the transport element 126 can the card cover along one is approximately parallel to the lateral surface of the drum 110 extending predetermined path with respect to the Drum 110 moves and then above this predetermined Web can be returned.
  • the direction of movement of the cover 120 is the direction of rotation of the drum along the specified path 110 opposite, as indicated by arrow 124.
  • everyone the card cover is on its along the specified path Provide a cover set on the side facing the drum set.
  • Fig. 7 are also Lid sets in the form of punctures in a rubber fabric Wire hook formed.
  • the drum is used to parallelize the individual fibers the raw material, for example in the form of cotton flakes with one with a sawtooth all-steel set 102 Licker 100 or a feed roller. That so supplied material is detected by the drum set 112 and from this in the direction of rotation indicated by arrow 114 carried.
  • the individual covers 120 usually flat bars carrying the flat sets 122 on, in which hardened guide pins are rigidly fixed, wherein the cover treads formed by the guide pins at least generally along the given route Plastic-formed slide guide lie on.
  • a lid are described for example in DE 43 04 148 A1.
  • the invention has for its object a method for operating to specify a card with which to avoid rapid Damage to the sets even after re-garnishing Carding performance achieved after initial start-up can be.
  • This invention is based on the knowledge that the deterioration observed during long-term operation of a card the carding effect not only on wear of the trimmings, but also on dirt and / or wear the lid tread is due. Through this The removal can impair the cover treads between the clothing tips of the lid clothing and the clothing tips the drum set to a value of less than Can be reduced by 0.15 mm, which is even when re-installing Lids and reel damage the sets can.

  • suitable lid has at least two tread areas, which are spaced apart along the predetermined path. For this purpose, two tread elements on the Support body of the lid set.
  • the surface pressure between the Lid running surface and the guide surface can be reduced if the pin forming the tread element in the area of the cover tread to form a substantially rectangular surface area is flattened.
  • the definition of the tread element on the supporting body of the cover can be force, shape and / or cohesive using a suitable adhesive respectively.
  • the cover tread is covered by a tread element is made of hardened steel Reworking the cover tread preferably using of boron nitride as an abrasive, particularly preferably with Using a boron nitride slip ring.
  • new tread element such as a grinding or Milling process to be carried out to the properties of the new tread element exactly to the conditions of to adapt the card actually used.
  • Editing the Cover tread of the new tread elements is special then required if not all of the card's lids with new ones Tread elements can be fitted to make an adjustment of the new tread elements to those already used Tread elements of other lids.
  • the drum 10 is essentially in the form of a circular cylinder formed and has a set 12 in the form of a Cylindrical axis of circular sawtooth wire.
