Embodiment Construction

[0012] The fiber feed trough 1 has a very long shaft depth, for example 600 Å, in which it is filled with fiber bundles 2 . Feed rollers 3 and 4 are installed at the lower end of the fiber feed trough, and these two feed rollers rotate at different speeds, and introduce fiber bundles, transport the fiber bundles to opening roller 6 . The carded fibers are wrapped, and the outer side of the roller rotating at a low peripheral speed has spikes, some of which point in the direction of rotation, and some point in the opposite direction of the direction of rotation.

[0013] The system described above can also be used for the feeding of fiber mats and for carding / combing.

Abstract

The invention relates to a differential feed device, especially to a device for introducing a thin-fiber mat from a large reserve well channel so as to make introducing rollers running at different speeds. The device comprises at least one pair of introducing rollers rotating in opposite directions and at least one combing roller, wherein, the two opposed introducing rollers jointly perform operations on the fiber at different speed.

Description

technical field [0001] The invention relates to a differential feed device. Background technique [0002] In the equipment for opening fiber bundles, in order to feed the fiber bundles to the opening rollers, the feeding device combined with the roller groove and the feed without pinch points using rebound rollers rotating in the opposite direction are the same. The right feed roller has also been used for more than 100 years. Such a pair of feed rollers is usually identical, but morphologically, the two rollers working together as a pair may also have different surface structures. [0003] The surface structure described above facilitates fiber pickup and holds the fibers for separation by the fast-running opening rollers. On the other hand, make it impossible for the fibers to wrap around the introduction roll. [0004] There are also introduction systems where one or two pairs of rollers introduce the fibers one after the other. The opening speed of the pair of roller...
