ABSTRACT:
An improved loop-forming assembly in a weaving machine for forming a surface fastener tape blank having a multiplicity of warp pile loops formed of loop-forming warp threads comprises: a plurality of parallel spaced lancets; a deflector extending transversely of and over the lancets; and a plurality of pairs of parallel spaced gate hook bars; the lancets, the deflector and the gate hook bars being kept free from one another. The deflector is axially reciprocable for laterally deflecting the threads in eyelets with respect to the lancets, respectively, and the gate hook bars are vertically reciprocable in timed relation to the deflector to lower the thus deflected threads by hook portions alternately at one side and then at the other side of the lancets so as to pass the threads over the lancets in a staggering fashion to form the warp pile loops.
