Abstract
A fiber web for use in the manufacture of slub or jaspe yarn is produced by a modification of a carding engine whereby a final fancy roller is mounted on a controllably movable support for movement towards and away from the surface of the carding drum, thereby varying the thickness of the sliver obtained before the sliver enters the doffing cylinder. The movement of the fancy roller may be controlled by a programme carried on an endless tape.
Claims5
Apparatus for the preparation of a web of textile fibers slivers having varying thickness along their lengths, used for the production of jaspe, comprising a carding engine having a drive motor, a carding drum and a plurality of worker rolls cooperating with said drum, to comb fibers thereon wherein the last worker roll acts as a fancy roll, and including support means supporting opposite ends of said fancy roll, and means to automatically and alternately displace said support means towards and away from the carding drum to effect controlled displacement of said fancy roll relative to said carding drum to vary the distance between the peripheral surface of said fancy roll and that of said carding drum, and means to remove said fibers from said carding drum to thereby cause a corresponding variation in the thickness of the fibers on said carding drum.
