Abstract: This device for winding, at high speed, a yarn onto a rotating support and comprising a yarn delivery system (5, 6), displaced so as to undergo a to-and-fro movement parallel to the surface of said support with rapid deceleration and acceleration at the point of reversal of the to-and-fro movement, is noteworthy in that the depositing yarn guide (6) is displaced by means of a moving element or cursor (5) associated with a magnetized plate (1) of a linear motor, supplied with two-phase or three-phase current, and in which the stator is formed by at least one assembly of elementary modules placed either face to face or placed so that each lies in the extension of another, each having a plurality of C-shaped magnetic circuits (4) that define, between the ends of their separated legs, an airgap inside which the magnetized plate (1) is positioned, comprising an alternation of North and South poles (N and S), which constitutes the moving element that displaces the cursor (5) carrying the yarn guide (6).

Abstract: A vapor phase heater includes a plurality of elongated hollow heater tracks. A vapor generator having a vapor generation chamber is in fluid communication with the interior of each track. At least one heat input tube extends through the vapor generation chamber wherein a vaporized fluid is supplied to the heat input tubes. A vapor flow connector communicates with the vapor generator and the interior of each track so as to provide conduits for vapor produced in the vapor generator to pass into each track.

At least one heat input tube extends through the vapour generation chamber wherein a vapourized fluid is supplied to the heat input tubes. A vapour flow connector communicates with the vapour generator and the interior of each track so as to provide conduits for vapour produced in the vapour generator to pass into each track.

Abstract: The invention concerns a method for producing a complex nonwoven fabric which consists in continuously producing a complex wherein a first web of a cellulosic fibres (4) is continuously sandwiched between two webs of spunbonded filaments (2, 7), and which consists in: producing a first web of spunbonded filaments (2), the bundle of extruded and drawn filaments being received on a mobile conveyor belt (3) in the form of a non-bonded lap; depositing on said web 92) by airlaid process a second web of cellulosic fibres (4); depositing on the textile web (4) a second web (7) of non-bonded continuous filaments; transferring the resulting complex onto an installation (9) for water-jet bonding and hydro-entanglement consolidation; and in drying the nonwoven mixed product and then recuperating it, for example in the form of a cloth wind-up (18).
