ABSTRACT OF THE DISCLOSURE The present invention relates to the provision of contours in deep-pile fabrics and especially to simulating contours found in natural furs and the like. The various means proposed in the prior art for controlling the shape of the fabric back have proven to be unsatisfactory. They have all caused some portions of the fabric to be stressed and strained excessively while other portions have been left uncontrollably loose. These conditions have caused contour shapes to be very irregular in the finished pile. The present invention overcomes these and other problems by providing a contour shear rest having a contour surface made up of elements forming a complement of a desired contour. The contour surface is formed so that the length of the travel path of fabric drawn across its face is uniform. Tension applied to fabric drawn across the various surfaces is therefore uniform and fabric distortion is substantially eliminated. Consequently, as the fabric is sheared, it is provided with desired natural-looking contours.
