VERFAHREN ZUM EINTRAGEN DES SCHUSSFADENS IN DAS KETTFACH VON WEBMASCHINEN

摘要

A method for laying weft thread in the warp shed used in needle looms is disclosed. This method consists in that the feeding and the receiving laying needles mutually reciprocate to transfer the weft thread at the moment of their closest approach. The needles meet at the midpoint of the distance between the starting points of their reciprocating movement for which purpose the needles are made different in length. The shorter needle is introduced into the warp shed with a time lag relative to the moment of inserting the longer needle thereinto, thus making the needles move in one direction while the weft thread is transferred, whereupon the needles return to their initial positions leaving the warp shed at the same time. At the expense of extending the time of contact of the needles during their movement in one direction, this method permits of significantly improving the conditions for catching the weft and sharply reducing the number of mispicks, loops, and double threads.
