Abstract
A sealing head for machines for the thermal treatment of filaments, includes a frame (1) fixed to a pressurized chamber traversed by a conveyor belt, a pair of superposed horizontal rollers (2 and 3), which are pressed against opposite surfaces of the conveyor belt, and sealing elements (4 and 5) to form a sealed closure between the rollers (2 and 3) and the frame (1). The sealing elements (4 and 5) to form a sealed closure between the rollers (2 and 3) and the frame (1) are each provided with integrated lubricating elements (4', 5'), under pressure or by capillarity. The invention is more particularly applicable to the field of the textile industry, in particular the treatment of filaments by thermal treatment machines presently called thermofixation machines.
