Abstract: The drawing apparatus for textile fibre webs comprises a series of pairs of olls, the peripheral velocity of the rolls of each pair being greater than the peripheral velocity of the preceding pair in the direction of advance of the web.Each roll has a resilient covering constituted by highly flexible steel wires that extend substantially radially. A smaller-diameter smooth roller is interposed between each pair of covered rolls and the following pair, the smaller diameter roller having a peripheral velocity equal to that of the following pair. The disposition of the smooth rollers is such as to impart a sinuous course to the web and keep the web in engagement with the metal wires of the covered rolls over substantial arcs. The drawing apparatus achieves higher drawing ratios with a good quality of the drawn web using a smaller number of pairs of rolls.

Abstract: A control roll is provided for use in the processing of staple fibers and comprises a plurality of radially and circumferentially spaced projections on the surface of a roll. The control roll is placed in the path of a strand of fibers and the individual fibers in the strand are physically oriented into parallel relation with one another and maintained in that relation until the fibers are processed as by drawing and twisting.
