METHOD FOR IMPROVING THE FEEDING BEHAVIOR OF A WEFT YARN, ESPECIALLY A WEFT YARN MADE OF SYNTHETIC FILAMENTS, DURING THE PRODUCTION OF FABRICS ON JET LOOMS, PARTICULARLY PNEUMATIC JET LOOMS, AND JET LOOM FOR CARRYING OUT SAID METHOD
METHOD FOR IMPROVING THE FEEDING BEHAVIOR OF A WEFT YARN, ESPECIALLY A WEFT YARN MADE OF SYNTHETIC FILAMENTS, DURING THE PRODUCTION OF FABRICS ON JET LOOMS, PARTICULARLY PNEUMATIC JET LOOMS, AND JET LOOM FOR CARRYING OUT SAID METHOD
The invention relates to a method for improving the entry behavior of a connected, in particular synthetic filament - weft yarn in the case on the weaving looms, in particular air nozzle looms, which shuts off thereon which comprises a known tängelprozess in the mixing tube a modification of the resulting main jet nozzle is connected, in particular with regard to a damaging change in the weft yarn structure, to a weft yarn length to define the waste, for the subsequent weft yarn, and on the holding operation of the thermal to dispense with by means of.According to the invention is achieved by the fact that the in the main jet nozzle (1) remaining weft yarn (7) in the direction of the weft insertion (15) according to the injector (2) of the main nozzle (1) of a clamping device (6) is clamped into the shed and the inserted length of the weft yarn (7) is tied by closing of the weaving shed and then the weft yarn (7) on the between the clamping device (6) and the insertion side setting remaining length during a predetermined angle of rotation of the weaving machine - main shaft is subjected to a tängelprozess.
