Abstract
A chipper for chipping wood material has first and second feed rollers at an inlet. The first and second feed rollers are secured to a frame of the chipper with the axes of the feed rollers being parallel and spaced apart. The first and second feed rollers are free to move in a direction generally transverse to the axes. The feed rollers are biased toward one another. A motor drives at least one of the feed rollers to rotate the feed roller about its axis of rotation.
