摘要:
A device for driving and guiding a rapier of a weaving machine, comprises a rotatable drive wheel (1) provided for driving a rapier rod (14) in a back and forth movement and a guide channel formed by adjustable guide bodies (10), (11) in order to guide the said rapier rod (14) according to a guide path in co-operation with the drive wheel (1). The guide bodies (10), (11) are part of a guide unit (9) which, as a whole, is adjustable in order to modify the distance between the guide path and the rotation shaft (2) of the drive wheel (1), and where the drive wheel (1) is continuously adjustable in the longitudinal direction of its shaft (2). 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.

The invention relates to an electronic dobby device (100) 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 (1,2) by means of a rod and lever system, wherein each rotor (1,2) is mounted on a rotor shaft (5,6) by means of an eccentric bearing, and wherein each rotor (1,2) is individually selected to be connected or not to the rotor shaft (5,6) 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 (1,2) with respect to the rotor shaft when the rotor (1,2) is disconnected from the rotor shaft (5,6) by the selection elements, wherein the said two rotors (1,2) each are eccentrically journalled on a different rotor shaft (5,6) and both rotor shafts (5,6) 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 (100).

摘要:
A weaving method and a fabric (1, 2) woven by the present method includes a ground fabric (100, 200) composed of ground warp yarns, one or more binding warp yarns (101, 201), first weft yarns (3) and second weft yarns (4a, 4b, 4′, 4″) which are tied up in the ground fabric. Additionally, one or more tension warp yearns (102, 202) and non-figure forming and/or figure forming pile warp yarns (6, 7), with figure forming pile warp yarns (6) form figure-forming pile burls (6a, 6b). At least one set of two successive figure forming pile burls (6a, 6b) in the warp direction are alternately tied up over the first weft yarn (3). The first weft yarn is situated on the back of the fabric (1, 2) outside the ground fabric (100, 200), and over the second weft yarn (4a, 4b, 4′, 4″).
摘要:
A method for weaving a pile fabric with areas having a corded structure, a backing fabric being woven on a weaving machine by inserting backing weft yarns during successive weft insertion cycles between binding and tension warp yarns, while pattern-weft yarns are inserted outside the backing fabric, and are covered by pile warp yarns forming cords. Successive series of different pattern-weft yarns are inserted into the pile fabric in areas having a corded structure and at least one pattern-weft yarn of each series is running essentially above the warp yarns in a first part of its trajectory and is forming the pattern, and is covered by pile warp yarns essentially forming cords in a second part of its trajectory, so that a predetermined pattern or design is formed. This enables the color palette and/or the effect palette to be modified across the width of the weaving machine with weft effects.
摘要:
The purpose of the invention consists in defining a method in which, in the process of producing pile fabrics in accordance with card designs having been made, support is given, before or during processing, by a file activating the Jacquard machine in order to avoid that mixed contours are occurring.
