ABSTRACT OF THE DISCLOSURE This invention relates to the provision of rotating baffle means for air movement control in a circular deep pile fabric knitting machine. Prior art devises use an exhaust system with an intake hood or bell located above the machine, and It serves to remove a considerable part of the stray fiber from the knitting area. Neverthless, the action of the air jets directed toward the center of the machine has the result of blowing substantial amounts of stray fiber Into the knitted tube as it is formed. Furthermore, the air jet associated with one stitch-forming position may disturb the air-flow patterns at one or more other stitch- forming positions in a way adversely affecting the uniformity with which fiber is held by needles in the latter positions. To minimize the un- desired accumulation of stray fiber on super structure and inside the knitted tube, the present invention provides a rotating baffle supported from below substantially closing the opening at knitting level of tubular fabric produced by circular pile fabric knitting machine, and deflects air jet carrying stray fiber up toward exhaust intake above machine. A secondary rotating baffle at a lower level further reduces movement of air with entrained fiber into tubular fabric, and carries stop motion ring. Rotation of the ring with the goods minimizes skewing at the tube slitting point.
