The present invention relates to a yarn storage device for a yarn processing machine, a method for supplementing a yarn store in said yarn storage device and a yarn processing machine provided with said yarn storage device, wherein the yarn storage device comprises storage units () and loading means () in order to add yarn in a selected storage unit, wherein at least one storage unit comprises a winding holder () that is provided to keep a yarn store in a state wound round a holder body (), and wherein preferably yarn is added in windings with a winding diameter (D) that is greater than the radial dimensions (D) of the holder body ().

Yarn storage device for a yarn processing machine

A fabric includes a backing fabric having binding warp yarns, weft yarns, and pile warp yarns interlaced with the weft yarns. In a weft receiving opening, one of the weft yarns is positioned at a back side relative to a weft separating warp yarn extending in the backing fabric in the warp direction and the other weft yarn is positioned at the pile side. A pile warp yarn is interlaced with the weft yarn positioned at the back side relative to the weft separating warp yarn to extend out of the backing fabric between this weft yarn and the other weft yarn. In a transition zone, two transition weft yarns provided immediately adjacent to each other in the warp direction extending through a weft receiving opening are positioned at substantially the same level in a direction that is perpendicular with a plane defined by the warp and weft directions and/or are not separated by a weft separating warp yarn.

Fabric and method of weaving a fabric, in particular a carpet

A method for weaving pile fabrics with pile-free zones, in which, on a weaving loom, in successive series of at least two successive weft insertion cycles in each case at least one ground weft thread () and at least two effect weft threads (),() having mutually different appearance-determining properties are inserted at well-defined weft-insertion levels, in which the effect weft threads (),() in each series are inserted in successive weft insertion cycles, and in which, in order to create a predetermined effect in at least one pile-free zone, the warp threads (-); (-); (-) are positioned with respect to the weft insertion levels such that at least one effect weft thread (),() runs on the pile side substantially uncovered.

A method for weaving pile fabrics with pile-free zones, in which, on a weaving loom, in successive series of at least two successive weft insertion cycles in each case at least one ground weft thread () and at least two effect weft threads (),() having mutually different appearance-determining properties are inserted at well-defined weft-insertion levels, in which the effect weft threads (),() in each series are inserted in successive weft insertion cycles, and in which, in order to create a predetermined effect in at least one pile-free zone, the warp threads (-);(-);(-) are positioned with respect to the weft insertion levels such that at least one effect weft thread (),() runs on the pile side substantially uncovered.

On the one hand, this invention relates to a method for manufacturing a toothed rack from an elastic material, the toothed rack being provided with teeth, the said toothed rack, in pre-stressed condition, being wrapped up in one or several layers of fiber reinforced synthetic cloth around at least part of the height of its lateral faces which are almost at right angles to the surface in which the teeth are situated and, on the other hand, a toothed rack manufactured according to this method. Furthermore, this invention relates to a rapier rod profile for a rapier weaving machine provided with a toothed rack according to the invention.

Device for driving a rapier motion in a weaving machine

The invention relates to an electronic dobby device () for controlling the motions of at least one weaving frame of a weaving machine, wherein the at least one weaving frame is connected to two rotors () by means of a rod and lever system, wherein each rotor () is mounted on a rotor shaft () by means of an eccentric bearing, and wherein each rotor () is individually selected to be connected or not to the rotor shaft () by means of one or several selection elements in accordance with the weaving pattern to be woven, in order to move between two possible positions that can be taken up by the rotor () with respect to the rotor shaft when the rotor () is disconnected from the rotor shaft () by the selection elements, wherein the said two rotors () each are eccentrically journalled on a different rotor shaft () and both rotor shafts () are rotating continuously and for rotating over a complete rotation require the same period of time, and in that the said weaving frame can take up at least three different positions during each machine cycle to weave the required weaving pattern. On the other hand, the invention relates to a weaving machine provided with such a dobby device ().

Cutting device for a face-to-face weaving machine, comprising a cutting knife and an upper () and a lower cutting rail () with an intermediate distance () which may be adjusted by means of one or several screw means (), the device comprising at least one first screw means () having a first () and a second threaded part with a mutually opposite screw thread having practically the same pitch, each threaded part () being designed in order to move a respective cutting rail as to height in the opposite direction, because of which the almost central position of the cutting knife with respect to the upper () and the lower () cutting rail is maintained, with the same deviation, when adapting the adjusted height of the jaw to a new height of the jaw.

Symmetrical measurement of jaw

This invention concerns a weft thread clamp with two jaws (), () that can be moved to an opened and closed position, with at least one jaw () being directly moveable to the closed position via fluid pressure. The moveable jaw is preferably () a moveable unit, preferably made of a light material or in a compact form, which is moveable as a complete unit under the influence of the fluid pressure. Such a weft thread clamp is more reliable and simpler, and has a quicker reaction speed than the known pneumatically controllable weft thread clamps. This invention also concerns a system for the presentation of weft threads to a weaving machine equipped with one or more such weft thread clamps, as well as a weaving machine equipped with such a presentation system.

A device for driving and guiding a rapier of a weaving machine, comprises a rotatable drive wheel () provided for driving a rapier rod () in a back and forth movement and a guide channel formed by adjustable guide bodies (), () in order to guide the said rapier rod () according to a guide path in co-operation with the drive wheel (). The guide bodies (), () are part of a guide unit () which, as a whole, is adjustable in order to modify the distance between the guide path and the rotation shaft () of the drive wheel (), and where the drive wheel () is continuously adjustable in the longitudinal direction of its shaft (). With this device the clearances of the rapier rod with respect to the drive wheel can be performed easily, rapidly and with great precision, so that this device is able to work with a minimum development of heat and wear.
