Abstract :
The use of powder clutches for regulation of torque in entry and exit bridles of tension levelers must take into consideration the constraints imposed by the slip requirements of the powder clutch. This paper provides guidelines for roll diameter sizing as a function of the maximum linear line speed and worst case application tension profiles such that the powder clutch always operates in a reasonable slip operating range
