A DEVICE FOR FEEDING DESIRED BLEND OF CARD SLIVER OR SPUN-BONDED TISSUES IN MACHINES

摘要

A textile fiber processing assembly includes a feed chute having a bottom portion provided with a fiber outlet through which fiber material is discharged; a fiber feeding arrangement positioned externally of the feed chute downstream of the outlet opening and including a feed roller and a counterelement. Either the feed roller or the counterelement is stationarily supported, while the other component is movably supported to allow excursions thereof towards and away from the respective other stationary component as a function of the thickness of fiber material passing through the fiber feeding arrangement. There are further provided a drive motor for rotating the feed roller; and a textile fiber processing machine having an input and a fiber processing roller situated at the input downstream of the fiber feeding arrangement. The feed roller adjoins the outlet and is arranged for drawing fiber material from the feed chute through the outlet and advancing the fiber material to the fiber processing roller. There is also provided a measuring member connected to the movably supported feed roller or counterelement and arranged for generating signals representing the excursions. The rpm of the feed roller is controlled as a function of the signals.
