Abstract
A chute feed having a chute formed in part by an upper perforated wall portion and a lower oscillating wall portion. Two compartments are formed adjacent the chute and are separated therefrom by the upper and lower wall portions, and a divider wall is disposed to extend from the front of the chute feed to a location between the upper and lower edges of the upper perforated wall portion, such divider wall separating the two compartments and permitting the compartments to be exposed to upper and lower parts of the perforated wall portion, respectively. A blower having an inlet connected to a location outside the chute feed directs a path of air around the opening roller of the chute feed, through the perforated wall portion, and into the upper compartment where the air, and any dust or micro-dust entrained therein is sucked from the upper compartment by an air outlet conduit adapted to be connected to the vacuum of the extractor associated with the card being fed by the chute feed, whereby the air flow serves to level the fiber in the chute and also to remove and exhaust dust and micro-dust from the fiber. The lower compartment causes air to be forced into the chute through the lower part of the perforated wall portion during movement of the oscillating wall portion in its non-densifying direction, such air acting to assist in compacting the fiber in the chute.
