Abstract
The arrangement for supplying a fiber processing machine, such as a card or the like, with fiber flock material comprises a feed device for feeding the fiber flock material to an opening roller having needles distributed over its cylindrical outer or jacket surface. In accordance with the invention, strip-shaped vanes or blades are provided on the outer or jacket surface of the opening roller. These strip-shaped vanes or blades extend substantially parallel to the surface generator lines or generatrices of the cylindrical outer or jacket surface of the opening roller and between the needles thereof. As a result of these measures there is obtained an essentially even or uniform, heavy batt with an appreciably higher batt weight in the feed chute.
