Abstract
A loop-forming apparatus of the type including a plurality of loop-forming mandrels each extending forwardly between and in parallel to a corresponding adjacent pair of ground warp threads beyond the cloth fell of a weaving machine. The apparatus has at least one leno deflector extending transversely of the mandrels and reciprocally movable in a substantially transverse direction to that of the length of the mandrel so as to deflect the course of loop-forming warp threads alternately to one side and then to the other side of corresponding mandrels, respectively. A plurality of pairs of spaced gate hooks each extend vertically at opposite sides of the corresponding one of the mandrels and are vertically reciprocable in timed relation to the leno deflector to capture and lower the deflected loop-forming warp thread alternately to opposite sides of the corresponding mandrel so as to pass the loop-forming warp thread over the mandrel to thereby form pile loops on a woven fabric. Operation controls intermittently control the reciprocating operation of the leno deflector at given intervals of time so as to form loop-forming surfaces and loop-free surfaces alternately in the weaving direction on the woven fabric.
