Abstract: A woven fabric, especially a jeans fabric, with a ground fabric (140) and a laid-in selvedge (135) is produced. In this regard, the end sections (138) of the weft threads (137) are folded over at the edge (147) of the woven fabric and are again guided back into the woven fabric. Thereby the ends (139) of the weft thread end sections (138) can be dispersed over a range a and cause optical disturbance. A field (144) with alphanumeric characters, logos or at least one color is woven into the laid-in selvedge (135). The field (144) serves for advertising purposes and makes the ends (139) of the weft thread end sections (138) completely or substantially invisible, in that the ends (139) are covered in a weave-technical manner on the top side and the bottom side of the woven fabric, or are given the same color as the warp threads (109 to 117) in the area of the field (144).

Abstract: A weaving machine starts-up in slow speed operation during a first weaving cycle following the machine start. To help avoid weft breaks, a method is provided to hold a weft thread inserted into the loom shed during the first weaving cycle. A sensor monitors the weft insertion. The inserted weft thread is held by binding threads at a location downstream from an inlet side of the loom shed, before the weft thread is bound by the warp threads. The binding of the weft thread by the binding threads is carried out dependent on a signal of the sensor.

Abstract: Even weft yarns having low tearing force shall be processible without problems on weaving machines, especially air-jet weaving machines, that are operated in the slow speed running in the first weaving cycle after a weaving machine start. This is achieved according to the invention in that the weft thread (3) inserted into a loom shed (4) in the first weaving cycle after a weaving machine start is bound by separate binding threads (8) temporally before the binding by the warp threads (2), and in that the binding by the binding threads (8) occurs spatially at at least one position of the loom shed (4) after its inlet.

Abstract: It is the object of the invention to avoid weaving defects, which due to a starting process of a projectile weaving machine in fabrics, especially such with ground weaves, as a cause of the starting process. The object is achieved according to the invention in that the projectile weaving machine is operated in the slow speed running after each starting process during the first weaving cycle, in that during the slow speed running the weft thread is inserted with a velocity adequate for the prescribed operating rotational speed, and in that the projectile weaving machine is operated with the prescribed operating rotational speed directly after the end of the first weaving cycle.

Abstract: A reed drive of a loom includes a reed shaft connected to a reed. A conversion gearing having an input element and an output element is provided at each end of the reed shaft. The input elements are coupled to driven shafts of electromotive rotary drives to produce a common rotational motion with the same rotational speed as the driven shafts. The conversion gearings convert the rotating motion of their input elements into a reversible rotation of the output elements, and the output elements are coupled to the reed shaft in a rotationally fixed manner. Thus, the number of complete rotations of an input element is equal to the number of complete motion cycles of the reed shaft per unit of time.

Abstract: A reed drive of a loom comprises a reed shaft (3) connected to the reed (1). A conversion gearing (7, 8) each having a respective input element (11, 12) and a respective output element (13, 14) is located at the ends of the reed shaft (3). The input elements (11, 12) are coupled to the driven shafts (23, 24) of electromotive rotary drives (19, 20) for effecting a common rotational motion of the same rotational speed. The conversion gearings (7, 8), alone, serve to convert the rotating motion of their input elements into a motion of the output elements (13, 14) whose direction of rotation can be reversed. To this end, the output elements (13, 14) are coupled to the reed shaft (3) in a rotationally fixed manner.

Abstract: A terry weaving method and a terry loom for carrying out the method. Subject matter of the terry weaving method is that a slay travel shortening does not result during the carrying out of partial beat-ups for the formation of a weft thread group, and thus the original weft thread insertion window remains maintained. The terry loom has a servo drive (7) that displaces the reed support shaft (4) in the direction of the shed forming means by at least the pre-beat-up distance (VD) while maintaining the basic stroke H of the reed (11) before the forming of the weft thread group, and that reverses or undoes the displacement by at least the pre-beat-up distance (VD) after the forming of the weft thread group.

Abstract: A drive arrangement is constructed for permitting the separate operation of a weaving machine and a shed forming machine. The drive arrangement compensates any r.p.m. variations of the weaving machine drive and of the shed forming machine relative to the drive shaft of the respective machine. This drive arrangement permits keeping the energy drawn from the electrical supply network during the start phase and the drive power to be provided for a normal operation of the weaving machine and of the shed forming machine optimally low.

Abstract: A method of operating a weaving machine and a shedding machine aims, to achieve so-called soft starts and soft stops, in particular, of the shedding machine. The weaving machine is equipped with an electromotive main drive and the shedding machine is equipped with an electromotive auxiliary drive. In the method the shedding machine is started at a time point (t1) that lies before the starting time point of the weaving machine, and, upon a triggered interruption of the weaving process, a shedding machine comes to the standstill at a time point (t5) that lies after the standstill time point (t4) of the weaving machine.

Abstract: A reed in a loom is driven or oscillated back and forth to perform the beat-up motion by a direct reed drive that avoids using the main loom drive for operating the reed. The direct drive is an electromagnetic motor which uses as one of its components a reed support shaft (4) either as a rotor or as a stator. The reed support shaft acting as a rotor carries a reed slay which mounts the reed to the rotor. When the reed support shaft acts as a stator, the reed slay is mounted to separate rotor elements. In both instances the reed support shaft is part of a rotary or linear electromagnetic direct drive motor construction.
