Sealing head for machines for thermal treatment of filaments
First Claim
1. Sealing head for machines for thermally treating filaments, which is essentially constituted by a frame (1) fixed to a pressurized chamber traversed by a conveyor belt, by a pair of horizontal superposed rollers (2 and 3), which are pressed against opposite surfaces of the conveyor belt, and by sealing means 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 and the sealing means (4 and 5) being connected to actuators for corresponding movement (8 and 9) characterized in that the sealing means (4 and 5) to form a sealed closure between the rollers (2 and 3) and the frame (1) are each provided with an integrated lubricating means (4′
- , 5′
), under pressure or by capillarity, each lubricating means being of the integrated type under pressure (4′
), (5′
), being present in the form of a porous body disposed between the support (4, 5) forming the sealing means and the superposed horizontal rollers (2 and 3) and being connected by its surface turned toward said support (4, 5) to a means (4″
, 5″
) for distributing a lubricant under pressure, said means (4″
, 5″
) being connected, externally of the support (4, 5), to a supply conduit for lubricant under pressure.

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 meachines.
