Abstract
A feeding device for fiber flocks or opened fibers for feeding a textile machine, especially a carding machine, has a first, upper vertical fiber chute which supplies the fibers or fiber flocks to rolls for opening of the fibers, and a lower fiber chute which accepts the fibers released by the rolls and discharges a fiber mat at the bottom end of the fiber chute by way of discharge rolls. The feeding device also has a segmented intake trough with several intake trough segments which cooperate with a segmented, clothing-covered first roll, which is divided into several roll segments, wherein the torque of the roll segments can be controlled individually and the widths of the gaps between the intake trough segments and the associated roll segments can be adjusted on a segment-by-segment basis.
