Abstract
The invention concerns an assembly of sets of tightly adjacent eye needles (12) for filling-yarn knitting machinery. One set each of eye needles (12) is anchored by injection-molding in supports (8,9) at mutually equidistant positions, the needles being mutually parallel by their main planes. Two supports (8,9) each with a set of eye needles (12) form one segment of eye needles. The heads (22) of the eye needles (12) of the first set (24) of needles alternatingly enter centrally between every two heads of the eye needles of the second set (25) of needles. The two sets of needles are fixed within the segments and are oblique in such a manner that a conceptual plane from one of the sets (24) of needles (plane (5) of the set) extending along the eye needles and through the heads of this set of needles intersects the plane (5') of the set of the other needle-set (25) in the region of the heads. As a result, very fine ribbons or tapes may be manufactured that require minute separations between the heads of the eye needles, while eye needles having comparatively thick stems nevertheless can be used and these stems furthermore can be anchored by injection-molding them in each support.
