Tension Control Brakes
A full line of Positorq oil shear tension control brakes from Force Control Industries are suitable for plastic film production as well for other tension control applications such as unwind stands in steel mills, tension stands in paper mills and unwind stands in paper converting mills. Operational speeds are controlled without chatter, stick slip or torque variation and can be controled over the entire speed range. Torque is controlled by pneumatic or hydraulic actuation pressure and is independent of speed. Sizes range from 53 Lb. Ft. up to 300,000 Lb. Ft., with continuous heat absorption capability up to 3000 thermal horsepower. A patented fluid recirculation system assures the fluid is continually flowing through the friction area and carrying the heat to the housing for dissipation. With noise levels below 50 dB these brakes are quiet enough for operators to work comfortably in the same area.
