ABSTRACT:
A device adapted for supporting a high inertia spool of stretchable strip material which strip material is withdrawn from the spool at varying rates by a strip applicating machine. The device includes a member which guides a length of the strip material being withdrawn. The guide member is adapted to be pivoted by tension in the strip material being withdrawn, and when pivoted activates a variable speed motor which rotates the spool to unwind the strip and maintain tension in the strip below an acceptable value. The motor is coupled to the spool through a worm drive which brakes rotation of the spool when the motor is de-energized to restrict over-running of the spool after tension in the strip is decreased.
