PROCESS FOR FITTING THREAD YARNS THAT ARE NOT ENHANCED, OR PARTIALLY CONNECTED, IN SPECIAL FIELD YARNS, SYNTHETIC FILAMENTS, AND TEARS FOR THE CONDUCT OF THE PROCESS

摘要

Intermingled filament yarns (1, 2) are inserted as weft alternately by jet tubes (3a, 4a) that are supplied with compressed air at pressure (P1.1, P1.2) of less than 1 bar. At a section (A-A) some distance from the exit the yarn is exposed to an intermingling jet directed at an angle to the forwarding airflow and supplied with air at a pressure greater than 1 bar, preferably 4 to 6 bar. An Independent claim is also included for an air jet loom equipped accordingly, having control valves timed to provide intermingling air pulses in time with the weft insertion cycle. The intermingled end of the weft is eventually cut off with the waste yarn.
