Abstract
A roll type stock feed apparatus having first and second support shafts mounted on a frame with the axes of the first and second shafts in parallel relation and disposed in a plane transverse to the feed path, a first roll mounted on the first support shaft with the roll is axis coaxial with the first shaft axis, and a second roll is mounted on the second support shaft for limited longitudinal tilting movement relative to the second shaft axis. Roll drive mechanism is provided for driving the first and second rolls to advance stock along the feed path and includes a first toothed coupling member mounted on the second roll and having annularly arranged teeth coaxial with the second roll axis and a second toothed coupling member having annularly arranged teeth coaxial with the second shaft axis, the teeth on the first and second coupling members having working clearance therebetween sufficient to accommodate limited tilting movement of the second roll relative to the second roll axis. Guides are provided to substantially prevent tilting movement of the second roll in a direction crosswise of a plane containing the first and second shaft axes.
