Abstract
An apparatus and process is described for deflecting a continuous yarn moving along a first to a second path to lay flat on a surface of an upstream roll of a pair of rolls at least adjacent a cutting zone defined by the circumferential contacting surfaces of the rolls of a cutting machine. The first path of movement is above and in a zone between the sides of one roll, the blade-carrying roll, which may comprise either the upstream or downstream roll, and the yarn is deflected at such time that it is being drawn at an operational speed of movement and at a speed equalized with the drawing speed of movement of other yarns.
