Abstract:
A modified windup in which package supports move in a linear motion as packages build on chucks in surface-driven engagement with drive roll. Fluid cylinders moving the chucks are connected via a hydraulic loop permitting free flow of fluid between the cylinders as yarn packages are wound thereby utilizing counter-balancing package weights for controlling force between the chucks and the drive roll.
