Abstract: A process of dyeing by deposition of spots of dyebaths of different colors on moving filaments, in a series of application stations, by abrupt cyclic or pseudo-random interruption of the deposition in the application stations, and a device for practicing this process. The process is characterized in that, in each application station, the moving filaments are abruptly taken out of contact with the dyebath by a linear or pseudo-linear actuating device acting on the dyebaths or on the moving filaments. The invention is more particularly applicable to the field of the textile industry, in particular the treatment of filaments, particularly by dyeing of the “spaced dyeing” type.

The device is more particularly applicable to the field of the textile industry, in particular the field of washing and/or dying yarn.

Abstract: A dye coating head for depositing dye from a bath onto moving filaments, is in the form of a box having first and second portions (1 and 2) articulately interconnected with an upper portion (1) fixed and a lower portion (2) vertically swingable. A guide (3) for individual filaments of a layer of filaments is mounted on a side of the box which is upstream when seen in the direction movement of the filaments. This guide (3) is transversely displaceable relative to the direction of movement of the filaments. The vertically swingable lower portion (2) has a front wall (7) which, when raised, closes a front portion of the box when the guide (3) is rearwardly moved.

Abstract: A liquid is vaporized by a device having at least one porous substrate exposed to a certain ambient pressure, means for supplying the substrate with liquid in order for it to be loaded with liquid starting from an upstream portion of the substrate, and at least one energy source for heating the substrate so that at least some of the liquid is vaporized. According to the invention, the means for supplying the substrate with liquid may include means for pressurizing the liquid to a pressure greater than ambient pressure, thereby creating a flow-rate greater than the flow-rate induced by capillarity and vaporization of the liquid alone when the substrate is held in a horizontal position. The invention may be applied to the production of water-vaporization equipment, particularly with electrical or gaseous energy supply.

Abstract: A steam generator includes an orifice for feeding water to a porous material, a heater element passing through said porous material, and an outlet orifice for the steam created by heating said water, wherein the porous material and its heater element are contained in a case disposed in a removable sealed cassette that is connected in operation to a fixed portion of the generator containing water feed means, means for controlling the heater elements, and means for taking off the steam. The sealed cassette is connected to the fixed portion of the generator by means of snap-fastenings in order to enable rapid connection and deconnection, and it includes a water admission orifice connected to an internal case containing a heater element for the water and around which a porous material is compressed, said case including orifices over its entire surface for evacuating the steam produced by the heater element, with the steam being extracted from the cassette via a steam outlet orifice.

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).

Abstract: In a method for continuously dyeing textile yarns (14), the yarns travel continuously in front of a succession of stations (15a, 15b, 15c) for applying dyes of different colors, each station applying a series of spots onto the yarns (14), so that each yarn includes a succession of spots forming a pattern extending over a certain length (L) of the yarn (14) and which is continuously repeated. The stations (15a, 15b, 15c) for applying the dye are commanded individually in order to corrupt the repetitiveness of the successive patterns. The method is useful for improving the quality of carpets obtained from textile yarns (14).

Abstract: A method for fastening a yarn end (2) on a bobbin (1), comprises placing the bobbin (1) horizontally on two spaced supports which support the bobbin along two lines parallel to the axis of the bobbin. A partial vacuum is created in a space located near the bobbin (1), the partial vacuum being sufficient to suck the non-fastened yarn end (2) into that space. The bobbin is caused to rotate in order to wind the non-fastened yarn end (2) on the bobbin. The yarn end (2) is fastened on the bobbin (1). While step (b) is being performed, the bobbin (1) is rotated at the same time in order to unwind the non-fastened yarn end (2) so that this end can engage by suction to a sufficient extent within the space located near the bobbin (1).
