Abstract: In the case of a paraffin waxing device for a travelling yarn, a rotating paraffin body is weighted in axial direction against a stopping face. The stopping face lies against the front surface of the paraffin body, over which the travelling yarn is guided. During the waxing process, undesired rubbing off of paraffin particles can soil the feed material or the machine elements. According to the invention, the stopping face is rolled on the rotating front surface. The rubbing-off of paraffin particles, in particular in the area of the stopping face, is hereby avoided.
Abstract: A device for waxing a yarn in a spinning machine which includes an annular wax roll, and means for rotatably supporting the wax roll. The support means includes a solid cylindrical member integrally connected to the wax roll so as to project from one end of the wax roll, and a support spindle associated with the cylindrical member for allowing the integral rotation of the cylindrical member and the wax roll. The waxing device is disposed that the yarn, which travels from a supply of yarn to a yarn winding-up mechanism, contacts both the projected periphery of the cylindrical member and the one end of the wax roll. The rotation of the wax roll is caused mainly by the yarn contacting the solid cylindrical member so that the wax roll is not adversely affected by the yarn even when changes occur in the travel condition of the yarn, so that no grooves or concaved lines are formed in the end face of the wax roll.
