Definitions

  • the present invention relates to textile carding apparatus.
  • the fibres are subjected to a carding operation to align the fibres for the purpose of increasing the longitudinal tensile strength of the fibrous material and in order to help in removing the residual impurities after the cleaning step.
  • the carded fibrous material leaves the doffer, which has removed the fibres from the carding cylinder, in the form of a web which is then condensed to form a generally circular cross-section sliver.
  • the carded web is removed from the carding cylinder by a doffer from which the web then has to be stripped before it is condensed to form the sliver.
  • condensing means is disclosed in GB-B-1208264 as using a continuous conveyor belt to support the web and to feed it in a direction transversely to the direction of movement of the web leaving the doffer, thereby assisting in condensing the sliver which is coiled into a can at one end of the belt, i.e. at one side of the carding apparatus.
  • a modification of the conveyor belt condensing means is disclosed in GB-B-1298855 where two separate conveyor belts feeding towards the centre of the web are employed.
  • the present invention provides a carding apparatus wherein the doffer unit comprises a doffer; a stripper roll co-operating with the doffer for removing the carded fibrous web from the doffer; a stripper blade arranged to assist the fibrous web in detaching from the stripper roll to move along a first direction; a condensing surface movable in a second direction transversely of the first direction of the carded fibrous material for the purposes of carrying the fibrous web, supported, in said second direction and condensing it to form a sliver; and a stationary support surface downstream of the stripper blade to support the detached carded fibrous web on its travel as far as the point of its engagement with the moving condensing surface, in use of the apparatus.
  • the doffer cylinder 1 rotates in the clockwise direction to carry the carded web upwardly towards the transfer point with a single fluted stripper roll 2 which also rotates in the clockwise direction and therefore has its circumference moving in a direction opposed to that of the doffer 1 at the nip.
  • a support bar 3 below the stripper roll 2 carries' both a web stripper blade 13 and a web support plate 4 which then supports the delicate carded staple fibre web 5, which has been stripped from the stripper roll 2 by the stripper blade 13, until the web is placed on the adjacent coplanar runs of two conveyor belts 6 supported on rollers 7 on a frame 8 which is pivotable about a horizontal axis 9 extending transversely across the carding apparatus.
  • each belt 6 there are two belts 6 each mounted on a respective pair of the rollers 7, with the four rollers 7 having their axes parallel and coplanar in the plane A extending transversely across the carding apparatus.
  • the direction of circulation of each of the belts 6 is such that the runs which are adjacent the fluted stripper roll 2 (the right-hand runs a viewed in the drawings) move towards the centre of the belt arrangement (i.e. towards the two innermost of the four support rollers 7) and thereby serve to condense the delicate staple fibre web 5 on the plate 4 to form a generally vertically extending sliver 10 moving towards the condensing trumpet 11 which feeds the calender rolls 12.
  • the fibrous web 5 is stripped from the clockwise-rotating fluted stripper roll 2 by co-operation with the stripper blade 13 which has a strip of its surface close to one edge 13a spring biased into contact with the roll 2, or more properly into contact with the exposed surface of the carded staple fibre web on the roll 2 leaving the transfer point between the fluted stripper roll 2 and the toothed doffer 1.
  • the stripper blade 13 With the web supported on the fluted stripper roll 2, the web detaches from the fluted stripper roll 2. The web is supported by the stripper blade 13 until it passes to and rests on the stationary support plate 4.
  • the stationary support plate 4 is capable of supporting the web and preventing breakdown of the delicate web on its travel from (a) the stripping location between the fluted stripper roll 2 and the spring biased stripper blade 13 towards (b) the zone of contact with the conveyor belts 6.
  • the preferred form of the support plate 4 has a generally flat upper run which carries the web from its point of stripping from the fluted stripper roll 2 towards the adjacent run of each endless belt 6, and at the edge of the plate adjacent to the belt 6 the support plate has a downwardly extending, preferably cylindrical, convex portion to guide the fibrous web 5 smoothly onto the ; condensing belt runs. It also has a convex upstream portion at the transition between the stationary support plate 4 and the stripper blade 13 which it contacts, thus presenting the web with a smooth leading edge on its path to the generally planar surface of the support plate 4.
  • both the non-operative edge of the blade 13 and a parallel and continuous sheet metal portion of the support plate 4 are carried by the same support bar 3 and it is therefore readily possible to re-position the stripping blade 13 while still maintaining the correct positioning of the support plate 4 which it contacts.
  • the precise positioning of the belts 6 in the solid line position 8 of Figure 1 relative to the support plate 4 is adjustable by means of an Allen key locking screw which can be released to allow pivoting of the belt take-off mechanism about its axis which travels along the circular locus 9a.
  • the belt take-off unit will, for example, be required to be movable to its out-of-the-way position while the carding apparatus is delivering carded web, for example for the purposes of inspection of the web to carry out a nep count.
  • Figure 2 shows the belt take-off unit as having a pinion 15 which is mechanically linked to the belts to drive them in the appropriate directions when the pinion 15 rotates in the clockwise sense as shown in Figure 2.
  • a further pinion 16 is carried by a rotary carrier 17 having its axis of rotation coincident with that of the stripper roll 2, and is spring-biased in the anti-clockwise direction by way of a spring 18.
  • a pinion (not shown in Figure 2) having substantially the same diameter as the stripper roll 2 and fixed for rotation therewith is constantly in mesh with the pinion 16 on the rotary carrier 17.
  • the spring 18 will hold the carrier 17 biased towards the belt take-off carrier so that drive to the pinion 15 by way of the pinion 16 is maintained.
  • the belt take-off carrier enters the sector of its locus of movement between the solid line position 8b of Figure 2 and the broken line position 8a of Figure 2 the carrier 17 is limited from further clockwise motion and drive to the pinion 15 is interrupted.
  • the support bar 3 is normally biased about its longitudinal axis in a direction which urges the stripper blade 13 towards the stripper roll 2, it is possible for the bar to be rotated to an out-of-the-way position for maintenance.
