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.

Abstract: The present invention relates to a detector for measuring the characteristics of a linear product of very great length relative to its other dimensions, on a production machine or the like. The detector operates without contact with the linear product and is provided with at least one means (1) having zones (2 and 3) for measurement relative to a mean position of the moving filament (4) and measuring the variation of the complex morpho-dimensional and/or positional characteristics of the filament (4), this latter varying, either by vibrating movement, or by displacement induced by the mean position of the axis of movement. The invention is applicable to the field of the measurement of the characteristics of linear products of very great length.

Abstract: The invention relates to a generic mattress system which is easily adjustable to differing and space varying stresses with limiting spring paths. It has a top mattress and a bottom mattress with supporting elements connected to a frame and located in the plane of a frame. The elements are in U-shape and bear elastic support elements fastened to crosspieces. The upper mattress can also have spring elements between the upper and lower support, with each spring element having a section of elastic material.

Abstract: Apparatus with endless screws for forming flat loops of textile yarn.The invention relates to an apparatus having endless screws for forming flat loops of yarn and depositing them on a conveyor belt.The apparatus comprises two endless screws (10 and 11) with parallel axes which are rotatingly driven in opposite directions, two support and guide members (12 and 13) disposed laterally with respect to the screws and two deviating rods (26, 27) equidistant from these screws. These members and these rods serve to carry the loops of yarn, to bring them forward to the vicinity of a conveyor belt (24) and to deposit them on its surface after having previously turned them over.This device is useful to allow the loops of yarn to be immediately turned over without necessitating an intermediate belt to turn them over.

Abstract: Installation for the continuous treatment of at least one textile yarn comprising means for continuously winding at least one yarn picked up on a reel, a deposit head for depositing this yarn on a conveyor belt, at least one thermal treatment enclosure area through which the yarn passes resting freely on the conveyor belt and means for taking up the yarn on the conveyor belt for rewinding it, wherein the thermal treatment enclosure area comprises a yarn drying apparatus using micro-wave or high frequency treatment, and forced ventilation means across the yarn and the conveyor belt.

Abstract: Device comprising two identical air capacitors for continuous measurement of the linear mass of textile products. The thread is passed through the air gap of one of the capacitors. Its presence causes differences in capacitance between the two capacitors which are used to detect any irregularities in the thread. The device is characterized in that it comprises a means of simultaneously modifying the air gap of both capacitors to enable different grades of material to be monitored.

Abstract: (a) A programmable knitting machine(b) Machine comprising a matrix formed of conductors (A.sub.1) intersected by conductors (B.sub.j) at a point of intersection (T.sub.ij), display means (4), means (11, 12, 15, 16) for bringing the conductors (A.sub.i and B.sub.j) into contact, and a microprocessor.(c) The invention concerns the programming of knitting machines.

Abstract: This invention concerns a home knitting machine comprising at least one straight needle bed member provided with grooves slidably receiving the knitting needles, a carriage which is movable on the needle bed member and which is provide with selection units and cam tracks for actuating and displacing the needles of the needle bed member, a programming installation comprising reading means which are electrically connected to the selection units and which are relatively movable with respect to a program card, means for relatively displacing, from one row to the next, the reading means with respect to the program card, mechanical means for connecting the programming installation to the carriage for successive reading of the rows of the program card by the reading means in synchronism with the movement of the carriage, this machine being characterized in that the means for relatively displacing from one row to the next the reading means relative to the program card comprise means for adjusting the pitch of the sca

Abstract: The process comprises the steps of depositing the yarn onto a conveyor belt in the form of a cohesive flexible continuous hollow cylindrical winding of yarns, said cylindrical winding being supported on said conveyor belt at least along a generatrix of said cylinder, said cylindrical winding being transported through a hood-shaped steaming chamber while following a conveying pass successively ascending, horizontal and descending, the treatment fluid being maintained air-free and pure within said chamber owing to relative specific weight effect.

Abstract: This invention is relative at domestic knitting machine consisting of at least one needle board supporting slidingly in grooves the knitting needles and a movable carriage parallel above the needle board, the carriage being provided with a lock fitted with an electromagnetic needle selection component, which machine is characterized in that the electromagnetic component is mounted on the lock with the aid of a guiding means ensuring free movement in a direction substantially perpendicular to the plane of the needle board.

Abstract: A hand knitting machine having a single or double needle bed is provided with a device for selecting needles. This device includes an electromagnetic means located on a movable carriage which is electrically and mechanically connected to a program matrix by an endless metallic ribbon tensioned between two rollers over the width of the needle bed. The selected needles are controlled by an assembly of fixed and movable cams, the active and inactive positions of the latter being determined by a knob and lever assembly.
