Abstract: A winding system includes a frame with a power driven shaft mounted on the frame and a work fluid source for providing work fluid at a selected variable pressure. A carrier block is mounted on the shaft with mandrel means being removably mounted on the carrier block for rotation therewith and including wound material support means for receiving material being wound. An annular piston and cylinder encircles the driven shaft and engages a drive disc rotation by the driven shaft having friction means on a surface engaging the carrier block so that the drive block is urged toward the carrier block with a force in proportion to the pressure of the work fluid to vary the winding tension provided by the mandrel.

Abstract: A thread winding system has a rectangular hollow central support column housing having front and rear panels through which a plurality of bobbin support shafts extend and are supported for rotation; the shafts are arranged in horizontal and vertical rows and each includes a friction drive member and a pivot latch means on its extreme outer end for maintaining a bobbin in position on each end of the shaft to be drivingly rotated. Thread guide frames each consisting of unitarily connected vertical and horizontal rods extending between the vertical and horizontal rows of bobbin supporting shafts are provided adjacent the front face and the rear face of the supporting column and are reciprocated by a rotating barrel cam on the interior of the support column with guide means on the frame guiding individual threads to a respective one of the bobbin members. A chain drive system on the interior of the support column drives the shafts and the barrel cam.
