Abstract: The present invention is a mechanism that reverses a product placed between a first upper conveyor belt and a second lower conveyor belt. The first one is linked to at least one cylinder on one end, characterized in that the reversal mechanism contains at least one means for clamping the product placed against the first conveyor belt moving on a portion of the periphery of the cylinder.

Abstract: Process for treating threads by knitting-unraveling includes: knitting several individual threads (2) on a multi-feed knitting machine (1); carrying out one or more heat, chemical or other treatments, in one or more chambers (7); carrying out, in an unraveling unit (4), an unraveling with pulling on the first knit thread and winding or beaming the unraveled threads (2) individually or carrying out on these individual threads another treatment operation or a production operation, optionally with an intermediate accumulation of the threads. The invention can be applied more particularly in the field of the textile industry, in particular the treatment of threads, particularly texturing by knitting-unraveling.

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: Device for joining yarns between two machines for treating yarns. The present invention relates to a device for joining yarns between two machines for treating yarns, such as thermofixing and winding or beaming machines or steaming and winding or beaming machines or between means of feeding a multitude of yarns and weaving or tufting machines, characterized in that it is primarily made up of a supporting frame (1), a means (2) for individually guiding the yarns coming from the downstream machine and inserting these yarns in the means (3) for joining by entangling, by fusion or otherwise, a means (4) of individually bringing in and temporarily holding the yarns coming from the upper machine (4), a device (5) for inserting these yarns in the means (3) for joining by entangling, by fusion or otherwise, sets (6 to 8) for locking the yarns in position before and during the joining by entangling, by fusion or otherwise, and a means of cutting the free ends of the yarns before said joining.

Abstract: The present invention relates to a process and device for knotting a yarn on a package. The process consists essentially in gripping the end (3) of the yarn and positioning the yarn under tension in prolongation of the last wound turn, in producing a slack loop parallel to the end (3) of the tensioned yarn, then in forming a twist by twisting a length of the slack loop with end (3) of the tensioned yarn, in then tightening the obtained twist on the package (1) and in cutting the remaining end of the yarn. The invention is more particularly applicable in the field of the textile industry, in particularly for the winding of yarns and particularly knotting an end of the yarn on a package.

Abstract: A machine for continuously dyeing textile yarns (20) comprises at least one dye application station (15A). The latter comprises dye-sprayer (14) and protective sheat (21) through which the yarns (20) extend, and which has an open portion (21a) situated in line with the dye-sprayer (14) and in which the yarns (20) are opposite dye-sprayer (14). A shutter (16) is arranged between the textile yarns (20) and the dye-sprayer (14) in order alternately to intercept or let through the jet (17) of dye sprayed towards the yarns (20).
