Abstract

An apparatus for imparting a braking force to an advancing strand is disclosed, and which includes a mechanical compensating arm brake followed in series by a movement dependent brake. The movement dependent brake may take any one of several forms, including an eddy-current brake which is directly connected to a roll which is driven by the strand, a hysteresis brake which is directly connected to a roll which is driven by the strand, or a brake of any type which is connected to a roll which is driven by the strand via a clutch, such as a centrifugal clutch, which is operated as a function of the speed of the movement of the strand.
