Embodiment Construction

[0023] The air jet loom has a control unit 1 . According to the description of US Patent 4673004, the weft yarn is fed by a prewinder 2 with a controlled magnetic clamp and blown by a main nozzle 4 into a shed. Each main nozzle 4 is supplied with compressed air via a controllable valve arrangement 5 . The weft thread is guided in the shed via relay nozzles 6 which receive compressed air in each case via valve means 7 . The valve devices 5 , 7 are designed, for example, as described in US Pat. No. 5,086,812, WO 97 / 29231 or WO 99 / 64651.

[0024] The arrival of the weft thread on the other side of the shed is monitored by means of a thread detector 8 . The weft thread that has been introduced is cut off by means of a controlled weft thread cutter 9, for example with the weft thread cutter disclosed by US Pat. No. 4,834,145. In addition to this, a drafting nozzle 10 as described in US Pat. No. 5,226,458 is provided in this embodiment, the drafting nozzle being supplied with air...

Abstract

When adjusting the weaving speed, values for the weaving parameters are determined and adjusted that are adapted to the modified weaving speed using one or more modification functions based on the values optimized for a certain weaving speed.

Description

technical field [0001] The invention relates to a method and a control device for adjusting weaving parameters of a loom. Background technique [0002] In weaving machines, it is well known to assign weaving parameters such as the pressure and / or quantity of compressed air to the nozzles, the start point and / or duration of the compressed air supply to the nozzles, the moment of cutting of the weft yarn, the weft yarn on the prewinder The moment of release and other weaving parameters are stored in the loom control. [0003] From US patents 4,458,726 and 4,673,004 it is known to vary a certain weaving parameter by means of an adjusting device and according to the moment at which the weft yarn arrives at the yarn line detector, in order to achieve a certain moment in the weaving cycle of a subsequent weft yarn. [0004] It is also known that for a predetermined weaving speed or a loom speed, i.e. for a predetermined yarn to be processed and / or a predetermined fabric pattern, ...
