ABSTRACT:
Apparatus and method for high pressure sizing, including sizing squeeze apparatus which effectively utilizes high pressure squeeze loading to remove excess sizing from the warp yarns, and thus to reduce the water evaporation requirement of the yarn. The high pressure sizing squeeze apparatus includes positive drive of the rubber-surface roll as well as the steel roll to prevent slippage which could strain the warp, and maintains a substantially invariant squeeze loading irrespective of variable tension in the roll drive. The surface speed of the rubber-covered squeeze roll may be slightly less than the surface speed of the steel roll, to reduce the torque required to drive the rubber-covered roll at relatively high squeeze pressures where substantial slippage is encountered. A torque limiter controls maximum axial drive torque supplied to the rubber-surface roll, in response to the magnitude of squeeze loading.
