Carding machine having a fine-fiber brush

Abstract From the Canadian patent

An improved carding process utilizing a brush attached to a cylinder carding machine for inhibiting the buildup of napped fibers. Mounted just downstream of the transfer region between cylinders where carding takes place, the brush is stationary with respect to the revolving cylinders. The brush is disposed across the face of the carding drum, with the nylon bristles of the brush engaged in the card-cloth wires of the drum. The bristles continuously brush straighten and force napped fibers down into the wires of the carding cylinder, which results in a thicker, heavier web of carded fibers and virtually eliminates buildup of fluffy fibers on the carding drum as well as the input drum.
