Abstract (en)
[origin: EP0882831A1] In the case of a tufting needle, as an individual needle and as an element of a needle module incorporating several such needles, with an eye (4) provided in the area of its tip (3) and a thread-guiding groove (5) on one side of the needle, starting from the eye (4) and running along the needle stem (2), the invention provides for a thread-feeding element (10; 12; 15; 21; 31; 37; 43; 46; 50; 59; 78) to be incorporated in the upper area of the stem of the thread-guiding groove (5), to introduce the thread into this groove. In particular, the thread-feeding element can take the form of a hook or a hole. It collects the thread in the upper area of the needle stem and supplies it to the thread-guiding groove, which conveys the thread under cover to the eye. This process of feeding in the thread along the length of the needle lowers the load on the needle and thread and reduces the frictional forces which occur during movement of the needle in the backing material. <IMAGE>
