Abstract: A weft thread tensioning device includes a weft thread path defining arrangement having two weft thread passage elements positioned at a distance with respect to each other for receiving a weft thread such as to extend along a straight weft thread path extending between the weft thread passage elements. A weft thread deflection element is positioned between the weft thread passage elements in the direction of the weft thread path. The weft thread deflection element is movable to act on a weft thread extending across the weft thread passage elements deflecting the weft thread between the weft thread passage elements out of the straight weft thread path. A deflection element drive moves the weft thread deflection element and includes a controller associated therewith for controlling the movement of the weft thread deflection element for deflecting a weft thread extending across the weft thread passage elements.

Abstract: Disclosed is an arrangement of a weaving machine and a yarn storage device which includes an upright flank with juxtaposed yarn stores, and an associated yarn-tensioning device which is arranged in the space between the yarn storage device and the weaving machine, including comprising at least one yarn-tensioning module, which carries at least one row of juxtaposed yarn-tensioning elements, where the direction of said row of yarn-tensioning elements, has an angle of inclination and/or forms an acute angle with a vertical plane which runs parallel or coincides with the plane in which an upright flank is situated.

Abstract: Disclosed is a yarn tensioning system for keeping at least one yarn, which is taken from a yarn storage system to a yarn take-off system of a weaving machine, under tension. The system includes a brake roller around which the yarn is at least partially wound, and a motor for supplying a torque to the brake roller, the motor being actuable in generator operation to keep the yarn under tension between the brake roller and the yarn take-off system. Also disclosed is a weaving machine including such a yarn tensioning system, as well as a method for keeping at least one yarn under tension, the at least one yarn being taken from a yarn storage system to a yarn take-off system.

Abstract: The present invention relates to a device for dyeing a moving yarn that comprises a liquid dye supply line, a first nozzle positioned above the yarn and configured to deposit dye on a first surface of the yarn, a second nozzle positioned above the yarn and configured to deposit dye on a second surface of the yarn corresponding to a surface opposite the first surface relative to the axis of the yarn, a synchronization mechanism for actuating the nozzles as a function of the movement of the yarn such that, between the first and the second nozzle, the yarn is able to pivot axially under the effect of the gravity of the dye deposited by the first nozzle.
