Abstract
An apparatus and method for minimizing web cinching during unwinding of rolls of web material of indeterminate length. The position of the float frame or support member (36) of an accumulator (32) for the web is monitored and a proportional signal is sent to a comparator (52) which produces an increasing output signal as the float frame opens in the accumulator and a decreasing signal as the float frame closes. The output signal is fed to an integrator (66) which produces a gradually increasing or decreasing contol signal for a voltage to pressure transducer (70) which operates a pneumatic brake (74).
