ABSTRACT:
Through operation of a driving crank, the knotting apparatus is advanced over the canvas holder, on the one hand, and the various tools for the knotting operation are actuated, on the other hand. By means of drawing tongs (95) comprising two gripping arms (74, 92) the yarn (94) is pulled into the region of a needle head (103). With the front ends of two snaring arms (78,79) a cut-off piece of yarn is hung over the needle head (103). By means of two cross-arms guided parallel to the needle head, the ends of the piece of yarn are led through an aperture in the needle pushed through the canvas, whereupon the needle is retracted in order to form the knot. The desired color can be selected by means of a color selector (14). The method and apparatus make it possible to knot yarn (94) of selectively different colors rapidly and uniformly to the canvas.
