ABSTRACT:
Apparatus for heat-treating textile yarn includes a heater tube (3) through which the yarn is passed, the tube (3) having a holder (2) at each end and a seal in the form of a stopper (5) fitted into a neck (4). The stopper (5) has a groove (10) on its outer surface for guiding the yarn through the heater tube (3). Steam is introduced at the yarn entry end of the heater tube (3), passes over the groove (10) and is removed via passages (11) in the stopper and a suction pipe (7) connected to the passages. The heater tube (3), suction tube (7) and steam supply tube (8) are surrounded by an insulating housing (1) to minimize heat losses.
