More Information
Summary:A continuous fabric tubing is prepared by helically winding non-woven webs on a rotating drum in partly overlapping relationship, stitching the partly superimposed turns to each other by needling, and axially pulling the tubing so formed from the drum. The take-up mechanism, which pulls the tubing from the drum, rotates with the drum, and an automatic cut-off mechanism may be provided for automatically cutting the continuous tubing to uniform, adjustable lengths. The tubing may consist entirely of monofilaments and other smooth fibers not capable of normal felting.
