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.
Claims4
Method for operating a projectile weaving machine, whereby during a weaving cycle at least one weft thread is inserted into a loom shed formed of warp threads, thereupon the inserted weft thread is held clamped at the inlet and outlet side of the loom shed and is cut to length, and thereafter the weft thread in the clamped held condition is beat-up against the beat-up edge of a woven fabric to be produced and bound by the warp threads, characterized in that the projectile weaving machine is operated in the slow speed running after a 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.
