<p>A cutting arm for a cutting machine for cutting velvet, corduroy or the like has one end of a cutting arm pivotally mounted on a frame for pivotal movement about a first axis. A cutting head having a cutting knife is mounted for pivotal movement about a second axis on the other end of the cutting arm. The first and second axes are disposed generally parallel to one another and actuating means are operatively connected between these axes to provide for pivotal movement of the cutting head relative to the cutting arm about the second axis as the cutting arm is pivoted on the frame about the first axis generally parallel to a web of material passing underneath the cutting head.</p> |
