Title: Driving of cutter for multiple-color weft yarn
Inventor: MORI KIYOAKI
IPC: D03D49/70
Filed: 1992-12-25
Abstract: PURPOSE:To produce a high-quality woven fabric by cutting multi-color weft yarns inserted in a prescribed order of selection of weft yarns between the weft insertion nozzles and the cloth fell at the optimum timing of weft yarn cutter operation preset corresponding to the kind of the yarn. CONSTITUTION:In driving of a weft yarn cutter for cutting multi-color weft yarns inserted through two weft insertion nozzles, a cutter drive controller is composed of a setting circuit, an electronic switch, a reference circuit and a driving circuit. In advance of operation of a loom, an operation timing of the weft yarn cutter (C) is input and set to the above-mentioned setting unit so that the tension of the yarn between the weft insertion nozzle (N) the cloth fell may be optimum corresponding to the kind of the weft yarn set to each of the two weft insertion nozzles (N). According as the loom is operated, an operation timing suitable for each of the above- mentioned two kinds of weft yarns is sent out to the electronic switch. The electronic switch inputs an operation timing suitable for the inserted weft yarn based on the received signal and a yarn-kind specification signal from a weft-yarn selection unit to a comparator. The comparator allows the drive circuit to cut the weft yarns when the rotation angle in the main rotation from an encoder agrees with the above- mentioned operation timing.
