Embodiment Construction

[0016] figure 1 A sealing head for a fiber heat treatment machine is shown by way of example, which mainly includes: a frame 1, which is fixed to a pressurized chamber (not shown) traversed by a conveyor belt (not shown); Horizontal rollers 2 and 3, which push against the opposite surfaces of the conveyor belt; sealing devices 4 and 5, which form a sealed closed cavity between the rollers 2, 3 and the frame 1. At least one horizontal roller 2 and the sealing means 4 and 5 are connected to actuators (not shown in detail) for corresponding movements. The frame 1 , which does not form part of the invention, is only represented by two transverse uprights, which serve to receive the rollers 2 and 3 .

[0017] In addition, if figure 2 with 3 As shown, the sealing means 4 and 5 are applied under pressure on the respective surfaces of the rollers 2 and 3 by means of actuators 8 and 9 comprising cylinders. Said cylinders act on the one hand on the sealing means 4, so that the seal...

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.

Description

technical field [0001] The present invention relates to the field of the textile industry, and in particular to the treatment of fibers by means of heat treatment machines, now known as heat setting machines, in particular their sealing heads, and sealing heads for this purpose. Background technique [0002] A fiber heat treatment machine mainly comprises a pressurized chamber for the heat treatment of textile fibers arranged on a conveyor belt moving through said pressurized chamber, said chamber being closed at its two ends by sealing heads. Each sealing head consists of: a frame, which is fixed to the pressurized chamber; a pair of horizontal rollers, which are stacked on top of each other or approach each other in a horizontal plane, the rollers push on the opposite surface of the conveyor belt and ensure that the material can be driven and a conveyor belt; a sealing device forming a sealed closed cavity between the rollers and the frame. [0003] In one known machine o...
