Abstract

In a needle support (1) of this type, the needles (6) fastened to a supporting strip (5) at a mutual distance from one another to form a needle bar are guided through bores (3) of the needle support (1) and are thereby fixed to the needle support (1) by a press fit. So as not to impair the strength of the press fit during a repeated reneedling of the needle support (1) as a result of a widening of the bores (3), and moreover to avoid having to adhere to narrow tolerances in the production of the bores (3), an axis-parallel recess (2) of greater width than the bores (3) is provided at the inner end of the bores (3) and the diameter of the bores (3) in the radial plane is somewhat larger than the diameter of the needle shanks (18). The needles (6) bear alternately on opposite sides of the needles (6) against a bearing point (7) in the recess (2) and against bearing points (8 and 9) at the inner and outer ends of the bores (3) under stress, thereby ensuring a very firm press fit as a result of the high elastic forces of the needles (6). <IMAGE>
