Multiple bolt turning machine

A multiple bolt turning machine comprising a winding star which is adapted to be rotated from one to the next of a plurality of bolt positions, at least one of said positions comprising a bolt winding position and at least one other of said positions comprising a bolt removal position, a feed roll adapted to engage a web of material being wound onto said bolt at said bolt winding position, first positioning means for shifting the position of said feed roll about a pivot axis spaced from and parallel to the axis of rotation of said feed roll as said winding star rotates to move a bolt from said winding position to said removal position thereby to maintain said feed roll in contact with the incoming web of material and in engagement with the exterior of said bolt during said movement of said bolt, and second positioning means operable concurrently with said first positioning means for adjusting the distance between said pivot axis and the axis of rotation of said feed roll to maintain the angle of contact between said feed roll and said web of material substantially constant throughout the movement of said bolt between said winding and removal positions, said feed roll being mounted in a frame which is mounted for pivotal motion about said pivot axis, said second positioning means comprising motor means mounted for movement with said frame as said frame is pivoted about said pivot axis.
