Abstract

A yarn false twist crimping apparatus includes a curved heating plate which faces away from the service aisle. A cover is positioned to overlie the upper surface of the heating plate, and the cover is mounted for movement between a closed position covering the heating plate and an open position wherein the heating plate is uncovered. To initially thread-up a yarn, the cover is closed and the yarn is guided to an intermediate position along the outside of the cover. The advance of the yarn is then commenced, and the cover is then momentarily opened so that the yarn drops onto the heating plate.
