Abstract

The invention relates to a method for manufacturing bearing stops 6 of a needle 2 on a counter-needle 3, comprising the following steps: - positioning the needle 2 resting on the counter-needle 3; - Measure, for each hole 8 provided to fix a stop 6, a support distance L, between the inner surface of the counter-needle 3 and the inner surface of the needle 2; - Construct a bending curve from the support distances L and the positions of the holes 8 along the counter-needle 3; and, - calculate for each stop 6, from the bending curve, the angle of a bearing surface of the stop against the needle 2. Such a method makes it possible to produce stops with the desired geometric tolerances, without resumption on site.
