Definitions

  • the invention relates to a card with a card cover, and with a rotating, fiber-guiding roller, which is provided with a clothing, and with this roller opposite fixed side walls and with an existing between each side wall and the roller, the free rotation of the roller ensuring gap.
  • a sealing strip is removably attached to the side of the roller and overlaps the cylinder surface of the roller without contact and axially projecting over the gap.
  • this measure does not entirely prevent fibers or tufts of fibers from accumulating between the cylinder surface of the roller and the overlapping sealing tape, or fibers or fiber tufts from reaching the zone within the roller and being able to be deposited anywhere.
  • such deposits can be compressed between stationary and rotating elements and, depending on the intensity of friction, heated to an undesirable degree.
  • An advantage of the invention is that by fixing the cover tape to the roller, no frictional heat has to be absorbed by the roller, but that this heat can be absorbed by the side wall and easily released into the ambient air.
  • Another advantage is the fact that the cover tape can be replaced or inserted without removing the side walls, which is firstly less expensive in terms of maintenance and secondly prevents the tape from being damaged during assembly.
  • a feed roller 3, a licker-in roller 4, a main roller or drum 5 and a take-off roller 6 are rotatably and drivably mounted in a manner not particularly shown.
  • a card cover 9 with tips 9a (FIG. 2), so that fiber material (not shown) between the tips 9a and the clothing 8 is known per se Way can be edited.
  • a side wall 11 is provided, which is fastened to the frame 1 by means of flanges 12.
  • the side wall 11 extends with a side wall part 11a into the vicinity of the cylinder surface 7 and an end face 13 (FIG.
  • a flexible, circularly curved arc 15 is adjustably arranged, which serves for the precise guidance of the cover 9 along the drum 5.
  • a textile masking tape 16 for. B. a felt band is provided, which is pressed by means of a tension band 17 (Fig. 2, 4 and 5) against an inner surface 18 of the drum 5.
  • a tension band 17 Fig. 2, 4 and 5
  • the cover strip 16 extends across the gap 14 and lies at an inner friction surface 19 of the Se i tenwand learnerss 11a.
  • the contact pressure of the cover tape 16 on this friction surface 19 is different depending on the difference A R of the two radii R1 and R2 (FIG. 5) and depending on the elasticity of the cover tape.
  • the difference A R and the elasticity of the masking tape material is selected so that when the drum 5 rotates, a sliding seal is produced without substantial heating.
  • a tab 20 is at the two ends of the strap. 21 (Fig. 4) attached.
  • the threaded tab 21 has a Ge for receiving a threaded bolt 22 wind bore (not shown).
  • a lock nut 23 fixes the threaded bolt 22 in the threaded bore.
  • the assembly of the cover band 16 together with the tension band 17 is done in that the opened band with one end ahead through a mounting opening 24 or. 25 in the wall parts 11b respectively. 11 is pushed until the entire band can be placed on the surfaces 18 and 19 mentioned. The tape is then pressed against the aforementioned surfaces 18 and 19 by rotating the threaded bolt 22.
  • the masking tape 16 essentially prevents air from flowing through the gap 14 and is therefore a measure to prevent as far as possible that fibers or tufts of fibers that are conveyed over the edge 26 of the clothing 8 can get into the gap 14.
  • Another measure serves to promote the tufts of fibers mentioned against the tips 9a of the card cover 9.
  • This measure comprises at least one conveyor pin 33 embedded in the surface 32 extending between the end face 13 and the clothing edge 26 (FIGS. 2 and 3).
  • the conveying pin is seen in the axial direction of the reel, is inclined at an angle a (FIG. 2) of approximately 30 ° to the side wall 11 and, viewed in the direction of rotation D of the reel 5, with an angle ⁇ (FIG. 3) of approximately 3 ° degrees backwards, measured from a radial R3, inclined in the drum 5.
  • a variant shown in FIG. 6 has a gap 34 which opens in the radial direction and replaces the gap 14 and which is formed by an obliquely provided end face 35 belonging to the roller 5 and by a likewise provided obliquely provided end face 36 belonging to the side wall 11a.
  • a conveyor pin 37 is inserted obliquely in the end face 35 such that it is arranged in relation to the roller 5 at the same inclinations as the pin 33.
  • the pin 37 is arranged close to the masking tape 16, approximately in the relation shown in FIG. 6.
  • the variant shown in FIG. 6 is also provided on both sides of the roller 5.
  • the funding pin 33, respectively. 37 can be removed without removing the corresponding side wall 11, i.e. H. without dismantling the card 2, in the area outside the card deck 9 replaced or be used.
