Abstract
In a textile yarn texturing machine, a cooling arrangement for the heated false-twisted yarn is provided by a tube having a guide at the inlet end and a guide on the diametrically opposed side of the tube at the outlet end to guide the yarn in a helical path around the outer surface of the tube. The yarn makes one-half turn around the tube during its travel from the inlet end to the outlet end. Holes on the yarn path in the first part of the tube are connected to a suction device for fume extraction, and a cooling fluid may be passed through the tube to enhance cooling. The tube may form the second part of the cooling arrangement and is preferably inclined downwardly from a horizontally disposed first part towards the false twist device. The cooling arrangement or at least the first part is aligned with the preferably horizontally disposed heater located above the operator's aisle of the machine.
