Abstract
A retainer frame supportiing pat type clearer members is arranged in opposed relation to a draft roller. The retainer frame is inserted at both longitudinal end portions thereof into insert grooves of supporting brackets mounted on roller stands or draft roller bearing members placed on the roller stands. The retainer frame is formed by folding a metal plate. Each of the clearer members is formed with stopper lugs at both side edges thereof. With this arrangement, each clearer member may be easily installed into the retainer frame, and a uniform projection of the clearer member from the retainer frame may be maintained.
