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).

Abstract: A device for positioning the conveyor belt running through machines for thermal treatment of filaments, essentially constituted by a pressurized chamber (1) traversed by a conveyor belt (2) enclosed at each end by a sealing head mounted on a frame or movable door (3) connected to the pressurized chamber (1) by a bellows (4), each sealing head including a head of horizontal superposed rollers (5, 6) which are pressed against the opposite surfaces of the conveyor belt (2). The device includes a positioning elements (8) and a position control elements (9) acting on a very short region immediately adjacent each sealing head. The invention is more particularly applicable in the field of the textile industry, in particular of the field of treating filaments by elements of thermal treatment machines currently called heat setting machines.

Abstract: The present invention relates to a machine for the thermal treatment of threads, which comprises a positioning means (8) and a position control means (9) acting on a very short area in the immediate proximity of each sealing head, where said positioning means (8) consists of an axle (10) for pivoting the frame or moving body holder (3), which is connected directly to said frame or moving body holder (3), and of an actuator (11) for pivoting the frame or moving body holder (3) acting on said frame or moving body holder (3) through the intermediary of a rod linkage (12), which is mounted between the edge of the frame or moving body holder (3) and said actuator (11). Machine characterized in that the device for positioning the conveyor belt (2) during its advance in the pressurized enclosure (1) is provided, on the side over which the sensor extends, namely below or above the conveyor belt (2), with a means for holding the conveyor belt (2) at a height separation with respect to the position control means (9).
