A take-up unit for winding strand material comprising a strand-tensioning device having a compensator arm and a compensator wheel at a free end thereof for carrying a strand material to be wound and an air cylinder having means for receiving air under pressure is described. The air cylinder is interconnected with the compensator arm, thereby compensating for a change in tension of the strand material being wound. A plurality of strand-tensioning devices are interconnected with a common air supply, permitting the adjustment of the tension in the plurality of strand-tensioning devices by regulating the air feed from the common supply.

Air tension for take-ups

A winder and method for winding a plurality of yarn strands on a package with each yarn strand on the package having the exact same length to provide an exceptionally low catenary yarn package is described. A plurality of yarn strands are fed individually to a plurality of godets, the first godet being driven at a slightly slower speed than the remaining godets to stabilize each yarn strand by underfeeding and tensioning each strand, and the remaining godets measuring and metering equally each strand, providing packages at predetermined tensions and package pressure for trouble-free unrolling and unwinding.

Non-catenary tow winder

A take-up mechanism for simultaneously winding a plurality of yarns, tapes, or other strands on a plurality of take-up spindles is described. The mechanism comprises a support unit, a plurality of yarn take-up spindles positioned in substantially vertical alignment on the support unit, and a motor or the like in cooperation with the take-up spindles for driving separately each of the plurality of spindles. A compensator arm assembly comprising a plurality of compensator arms with each having a guide roll is positioned in substantially vertical alignment relative to the take-up spindles, with each of the compensator arms of the assembly individually controlling the speed of the drive motor for a take-up spindle. The plurality of yarn strands are fed to the compensator arm guide rolls at an angle of at least 60 degrees and no greater than 90 degrees. The take-up mechanism can be arranged in a compact manner which is of critical concern in a factory.

Take-up mechanism

A take-up mechanism for winding strand material at low speeds comprising a take-up spindle and traverse mechanism driven by a torque motor having a flywheel interconnected in the drive system is described. The flywheel controls power fluctuation during the strand winding operation and provides for a substantially uniform tension on the yarn strand during winding.
