Abstract
A web handling apparatus for supplying material to a metal forming machine wherein an uncoiler unit is mounted on a frame to draw metal web from a coil. A pivot support is mounted on the frame and supports a dancer arm with a track roller assembly. The dancer arm is pivoted to the roller assembly at one end and is connected to a pivot support at the other end in a manner such that the arm is capable of relative movement axially with respect to the pivot. Movement of the track roller assembly is limited to a vertical path by a pair of vertical tracks on the frame. The pivot support is connected to a rotary transducer for controlling the speed of drive rolls which regulate the delivery of metal web into the metal forming machine.
