Abstract:
In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, which is supplied by means of a supply device to a fiber-sorting device, especially a combing device, for removal of the combed fiber material at least one take-off device with a sliver-forming element is present, downstream of which is a drafting system. To increase productivity and obtain an improved combed sliver, downstream of the supply device there are at least two rotatably mounted rollers rotating rapidly without interruption, which are provided with the clamping devices for the fiber bundle, and between the sliver-forming element and the drafting system at least one conveyor element for a formed combed sliver is present.

Abstract:
In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, clamping devices are provided which clamp the fiber bundle at a distance from its free end, and a mechanical arrangement is present which generates a combing action from the clamping site to the free end, in order to loosen and remove non-clamped constituents. To enable productivity to be substantially increased in a simple manner and an improved combed sliver to be obtained, downstream of the supply device there are arranged at least two rotatably mounted rollers, clamping devices being distributed spaced apart in the region of at least one said roller's periphery, and the arrangement for generating a combing action is inside the roller.

In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, which is supplied to a fiber-sorting device, especially a combing device, having clamping devices which clamp the fiber bundle at a distance from its free end, which is combed to remove non-clamped constituents, the clamping devices each comprise two clamping jaws. To increase productivity and to enable an improved combed sliver to be obtained, downstream of the supply device there are arranged at least two rotatably mounted rollers rotating rapidly without interruption, the clamping devices being spaced apart in the region of the periphery of the rollers, and each clamping device comprising at least one nipper part at least partially of a lightweight material. The clamping jaws may have a high coefficient of friction in the region of their clamping surfaces.

Abstract:
The "cleaning-out" capability of a flat combing machine is increased by decreasing the distance between the jaw of the tong of the flat comber and the points of the opposed rows of needles on the round comber to a minimum distance and keeping this minimum distance constant. The needles are arranged on the round comber such that the radius of the needle points of the rows of needles lying side by side to the pivot of the round comber decreases, then increases, counter to the direction of rotation of the round comber. The tong is suspended by a pendulum and the distance between the pivot of the pendulum and the axis of the round comber is less than the sum of the maximum radius needle points to the pivot of the round comber, plus the minimum distance from the jaw of the tong to the needle points, plus the radius of the jaw of the tong to the pivot of the pendulum.
