Abstract

A yarn heating apparatus for use in a false twist crimping machine wherein the advancing yarn is guided along a laterally zigzagged path through the apparatus by means of yarn guides which are alternately arranged on opposite sides of the yarn. The yarn guides are of cylindrical configuration so as to present broadly curved contact surfaces in engagement with the yarn.
