Abstract
The present invention relates to a machine for the thermal treatment of threads, which comprises a positioning mechanism (8) and a position control mechanism (9) acting on a very short area in the immediate proximity of each sealing head. The positioning mechanism (8) includes an axle (10) for pivoting the frame (3), connected directly to the frame (3), and an actuator (11) for pivoting the frame, which is acting on said frame (3) through the intermediary of a rod linkage (12), mounted between the edge of the frame (3) and the actuator (11). The device for positioning the conveyor belt (2) during its advance in the pressurized enclosure (1) is provided, with a mechanism for holding the conveyor belt (2) at a height separation with respect to the position control mechanism (9).
