ABSTRACT:
A machine is disclosed which forms a tucked selvedge in fabrics produced on shuttle-less looms, of the type in which at least two weft threads are tucked simultaneously in the same warp shed, and in which the principal shaft rotates at a number of revolutions equal to that of the shaft of the loom on which the machine for forming tucked selvedge is mounted divided by thenumber of weft threads tucked simultaneously in the same warp shed. The movement of the hook-needle, the thread-seizing device or pincer and the weft-thread cutting unit, or scissors, is at each instant positively controlled by a set of cams mounted on the shaft of the tucked selvedge forming machine and connected with the said hook-needle through respective linkage systems, the said cams being operative for an angle equal to 360.degree. divided by the number of weft threads that are simultaneously tucked in the same warp shed.
