Method and apparatus for controlling the tension of wire being pulled from a wire spool on a bead wire letoff stand

摘要

The present invention relates to an improved bead wire letoff assembly and method of operation that controls the tension of wire being pulled from a wire spool mounted to the bead wire letoff assembly. The improved wire letoff assembly can accurately control the rotational speed of the wire spool and incorporates a cam plate and tension arm linkage to control the braking force applied to the wire spool.
