Apparatus for the sorting or selection of a fibre sliver comprising textile fibres, especially for combing

Abstract

An apparatus is used for carrying out fiber finishing or fiber selecting on fiber strip. Especially in an apparatus for combing, the fiber strip is supplied to a fiber finishing device by supply device; especially the combing device includes clamping device clamping the fiber strip on the certain distance far away from the free end thereof, a device for generating combing effect from clamping point to the free end of the fiber strip to loose and remove nor-clamping composition, such as short fiber, hair knot, dust and so on from the free end. At least one roller capable of rotating is installed on the upstream of the supply device in order to improve the amounts (productivity) generated each hour and obtain improving fiber strip. The clamping equipment used in the fiber strip is set on the roller, the periphery of which is distributed with interval around the stone roller. And the device (combing element) for generating combing effect is connected with the periphery of the roller.

Description

technical field [0001] The invention relates to a device for fiber finishing or fiber selection, in particular carding, of a fiber sliver comprising textile fibers, the fiber sliver being supplied from a supply device to a fiber finishing device, in particular a carding device, in which device there is a clamp A holding device and a mechanical device that holds the fiber strip at a distance from its free end, the mechanism that produces a carding action from the point of holding to the free end of the fiber strip to loosen and remove unclamped from the free end components such as short fibers, nits, dust, etc. Background technique [0002] In practice, a card is used to remove natural impurities contained in the cotton or wool fibers and to parallelize the fibers of the sliver. To this end, a previously prepared fiber strip is clamped between the jaws of a nipper arrangement such that a specific sub-length of fiber (called "fiber tuft") protrudes in front of the jaws. The ...

AI Technical Summary

Problems solved by technology

Additional disadvantages arise from large mass accelerations and counter-movements which, as a result, make it impossible to obtain high operating speeds

Finally, considerable machine vibrations lead to irregular deposition of card strips

Furthermore, the degree of retraction (ecartement), i.e. the distance between the nipper lip of the lower nipper and the clamping point of the separating roller, is structurally and spatially limited
