Abstract
The fiber flock removal apparatus has a pair of removal rolls which may be adjusted in height relative to each other to obtain different depths of penetration into the fiber bales. The removal rolls may rotate codirectionally with the direction of travel or may operate in contra-direction with respect to the direction of travel. The rolls may be mounted individually for vertical movement relative to each other or may be mounted in a common removal means which is pivotal about a horizontal axis to achieve adjustability in the relative heights of the removal rolls. In one embodiment, the rolls are maintained in a common horizontal plane while grid bars are angularly adjusted to obtain different depths of penetration of the removal rolls into the fiber bales.
