  • the grinding elements are preferably elastically bendable.
  • the grinding elements can be arranged so that they are in operation over the Working width of the card be distributed.
  • they may be of an elongated Carrier be worn, e.g. so that each sanding element at one end on Carrier is moored and protrudes from its attachment point transverse to the carrier.
  • the carrier can in operation on the card rack by means of a holder in a be mounted approximately predetermined relationship to the revolving flat unit, e.g. such that the covers are ground during the "return".
  • the abrasive elements, the carrier and the holder together may be a device formed in the card, e.g. such that the device with the card itself put into operation.
  • the card can be a drive or a controller for the grinding device.
  • the device can be designed in this way that it can be grown on the card, it could e.g. an own Drive or own control include.
  • the present invention is a first invention.
  • a grinding apparatus characterized in that it a lifting device has, with which a clothing carrier delivered to the grinding elements can be.
  • the predetermined immersion depth preferably results from the delivery of the clothing carrier (a flat bar) to the grinder, with the delivery of the device is not excluded on the clothing carrier.
  • a controllable Delivery device can be provided.
  • the arrangement can be made such that a change in the immersion depth is at least partially compensated for due to wear of the abrasive elements, e.g. by a corresponding adjustment of the delivery movement.
  • Fig. 1 is a known Wanderdeckelkarde 1, for example, the card C50 the applicant, shown schematically.
  • the fiber material is dissolved in the form of and purified flakes fed into the hopper 2, by a breeze or Vorreisser 3 taken as a Wattenvorlage, a drum or drum. 4 handed over and disassembled and cleaned by a traveling lid set. Fibers from the On the spool 4 located nonwoven fabric are then removed by a customer 7 and in an outlet part 8 consisting of different rolls a card sliver 9 formed.
  • This card sliver 9 is then from a tape storage 10 stored in a transport can 11.
  • the card is provided with a "main suction", with which waste can be removed. Such a suction is not in Fig.

But it is only half of the circumference of the sleeve 59 is occupied with bristles 50, the other Half bears the aforementioned grinding elements 42.
  • the abrasive elements 42 in this embodiment are similar to the bristles 50 at least therein, that they are formed as elongated, elastically bendable elements which are approximately radially protruding from the lateral surface of the sleeve 59.
  • the abrasive elements 42 are also more flexible as the wires 40, so that in the case of touching such an element with a Wire piece in a relative movement of the element and the wire, the grinding element 42 has to give way.
  • the elements 42 are significantly shorter than the bristles 50, so that they only the "head parts" of the clothing wires 40 (above the respective knee 41).
  • the speed of the free end portion of each element 42 is nevertheless greater than the speed of the clothing wires 40 in the direction of movement 15.

  • Each pass of the abrasive elements 42 to the Surfaces 43 is a polishing or a grinding of the side surfaces 43 instead.
  • the Aggressiveness of the polishing or grinding action depends on the design of the grinding elements and the speed of the relative movement. The optimal effect for one given wire type can be determined empirically.
  • the variant according to FIG. 5 comprises a helical arrangement of grinding elements 42 along a cylindrical support.
  • Each element is referred to as a bristle 45 (see in particular the detail - Fig. 5A) is formed.

  • the earlier invention is not limited thereto.
  • the Carding could e.g. merely have attachment points where a holder of the grinding device can be attached.
  • the device itself could then go from card to card Carried card and mounted only when needed on a specific card and in operation be taken.
  • Such a device could have its own drive, to turn the support carrying the sanding elements or could merely have a coupling to a temporary connection with the drive of the Machine allow.
  • the preferred solution according to the previous invention included a grinder with its own “infrastructure” (carrier, drive, etc.) and with grinding elements according to FIG. 5, wherein the carrier 59 is preferably "fully populated” (instead of merely helical Rows of abrasive elements), i. practically over the entire circumference should be occupied with abrasive elements. Trial testing of this design now leads to certain optimizations.
  • Fig. 6 consists of a zig-zag-shaped row of bristle groups along each half-shell.
  • the single ones Bristles are shown in Figure 5A - each consists of a filamentary nylon substrate, interspersed with silicon carbide. With the gradual abrasion of the bristle new abrasive particles are exposed. From the number of "bristle lines" L results the number of clothing tips that are ground simultaneously. This can be dependent the output power of the drive can be selected.
  • the lifting device 26 comprises two lifting elements 28, each near a Kardeconceschilds (not shown) are arranged. These elements are perpendicular to and from between a lower standby or rest position and a work position by a respective pneumatic cylinder 29 and lever 30 movable. Each lever element 28 is provided with a ramp 31 and a horizontal support surface 32.
  • the card itself comprises a compressed air supply 27 for the lifting device 26 and a controller (not shown) for the brush drive 22.

  • the lifting elements 28 press the covers at each end of the cover 13 13 against a stop surface 70 of a stop element 71.
  • the stop surface 70 is at a predetermined distance from the grinding elements 42. Through these stop surfaces we set the penetration depth of the grinding elements 42 in the clothing 14. Since the clothing height decreases with each grinding process, the penetration depth for optimum However, grinding requires a certain depth, it is particularly advantageous when the abutment surface 70 is adjustable with respect to the abrasive elements 42.
  • the device After the clothing tips have been ground, the device is again by turned off, that the power supply to the lifting device 26 and the brush drive 22nd prevented and the suction channel 23 through the flap (not shown) of the main suction 25 is disconnected again.
  • the lid 13 move accordingly only along the normal lid path and they are no longer the grinding brush delivered. After a period of operation without grinding the lid, the grinder can be put back into service to the quality of carding in the main carding zone to maintain a desired level.
  • the abrasive bristles become 42 shortened by wear compared to their original lengths. Although the Bristles 42 are still operational, the required minimum immersion depth ET (with unchanged cover delivery) can no longer be reached.
  • This problem could be solved in principle by the fact that the housing 20 relative to the card cage is adjustable. In the preferred variant but the Zustellieri changed to compensate for the shortening of the bristles 42. This can be done be that a stop (not shown) is provided to the (raised) To determine positions of the lifting elements 28 during delivery of the lids 13, wherein the position of the stop of the brush is variable with respect to.

  • a portable device could include a lid delivery device. However, this is not absolutely necessary for such a device. First, it is the common one Practice of the card manufacturer to provide and even install Deckelabhebevorraumen, to allow the grinding of the lid with a conventional grinding roller and secondly, it is more possible to grow a portable device that Immersion depth to be determined by the adjustment of the device holder, i. without the Lid ever deliver the brush. It will also be clear that one portable device is more suitable for manual operation, although timers or Cover counters are easily used to control a grinding cycle could.
  • a portable device could be designed for use while the card is still running, but will usually come to use with non-producing card. in the In the latter case, it is not absolutely necessary to have the grinder in a specific relationship to install the lid cleaning, as the lid during a "service” in any case be cleaned regardless of the cleaning device of the card.

Since the "side cut" for the all-steel set without Meaning is, the elements can be changed so that they are mainly on the (radially outwardly facing) front sides of the clothing teeth act. To For example, the elasticity or design (e.g., width) of the abrasive elements can be changed in such a way they are less likely to have a tendency between the clothing elements penetrate, but more the ability to move in the direction of the clothing elements to bend. Instead of abrasive bristles one could e.g. Choose slats that are on the front sides of the fitting teeth "support". Such a grinder could Also used for grinding drum, licker-on, or customer sets become.
