Abstract
An arrangement for transporting yarn through a heat setting chamber has a rotatably driven central mast which is equipped with transport belts arranged around the mast in the form of a polygon in cross section. At least one yarn is wound around the transport belts in loops by means of a winding flyer. At the latest when arriving at the heat setting chamber, the loops should have a larger circumference than the polygon formed by the transport belts for the purpose of forming a shrinkage reserve. This is achieved in that auxiliary belts, ending upstream of the heat setting chamber, are arranged in the area of the winding flyer, the speed of which auxiliary belts corresponds to the speed of the transport belts and which enlarge the polygon to the amount of the desired shrinkage reserve.
