Abstract:
A bead wire let-off assembly, characterized by:a brake system for applying a braking pressure to a rotating spool having bead wire unwound therefrom; a pressure regulator controlling the braking pressure applied by the brake system; a tension responsive control arm engaging the bead wire and pivotably movable in response to a change in tension of the bead wire to control the braking pressure applied by the brake system as a function of the position of the control arm; the brake system is further characterized by: a first axle secured to and extending outward from the rotating spool, the first axle having a first centerline therethrough about which the spool rotates; a first gear wheel attached to the first axle; a second axle having a second centerline therethrough, the second centerline being disposed in parallel relation to the first centerline; a second gear wheel secured to the second axle so that the first wheel gear is in engaging relationship with the second gear; and a pressure activated brake mechanism for applying a braking force to the second axle.
