Abstract: The present invention relates to a sealing head for machines for heat treating threads, comprising a frame fixed to a pressurized chamber through which a conveyor belt passes, a pair of horizontal rollers placed on top of each other and pressed against the opposite faces of the conveyor belt and of seals to form a sealed closure between the rollers and the frame, at least one of the horizontal rollers and the seals being connected to the corresponding movement actuators. Sealing head characterized in that the actuators of the horizontal roller or rollers and the seals between the rollers and the frame are in the form of pneumatic actuators without pistons, namely of the balloon or bellows type.

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.

Abstract: The present invention relates to a sealing head for machines for heat treating threads, comprising a frame (1) fixed to a pressurised chamber through which a conveyor belt passes, a pair of horizontal rollers (2 and 3) placed on top of each other and pressed against the opposite faces of the conveyor belt and of seals (4 and 5) to form a sealed closure between the rollers (2 and 3) and the frame (1), at least one (2) of the horizontal rollers (2 and 3) and the seals (4 and 5) being connected to the corresponding movement actuators (6 to 8). Sealing head characterised in that the actuators (6 to 8) of the horizontal roller or rollers (2 and/or 3) and the seals (4 and 5) between the rollers (2 and 3) and the frame (1) are in the form of pneumatic actuators without pistons, namely of the balloon or bellows type.

Abstract: The rack (1) for supporting bobbins (2) of filament is made up of several superposed rows of bobbins (2) mounted on spindles (X-X'). The rack (1) has a zone (3) for intermediate storage of bobbins (2) in which said bobbins are placed next to each other on a support (4), a conveyor (7, 8) being provided for automatically conveying the bobbins (2) to the storage zone. To be used for rationalizing the transfer of bobbins and the positioning of bobbins in a rack.
