Abstract: The excess covering material is trimmed from a workpiece using a blade assembly having side by side blade segments with cutting edges aligned with the contour to be cut. A rubber roller applies a longitudinal cutting force to the blade segments in sequential fashion by rolling across the blade segments ends opposite the cutting ends. The blade segments are returned to the noncutting position by a tension wire threaded through a notch in the shaft of each of the blade segments. Cutting pressure is adequate to cut through at least three layers of covering material without scoring the substrate. The rubber roller provides ceertain resiliency which helps control the cutting pressure.

Abstract: An electric hair clipper is disclosed which has a plurality of spaced cutting teeth. With this clipper, hair strands may be cut by passing the hair clipper over the hair in a series of swift, flowing strokes. The clipper may be passed over the hair at the outer periphery of the hair, or it may be passed over the hair within the periphery, to change the hair style. The hair clipper may also be used to thin or layer hair. In one such method of thinning or layering hair, the operator passes a comb through the hair in a swift stroke, creating a trough in the hair behind the comb. The hair clipper follows the comb in the trough, cutting hair strands which are displaced by the comb as the hair returns to its natural position. If desired, the clipper can be passed through the hair at an angle away from the scalp, so that the hair strands are cut different lengths.
