Abstract (en)
[origin: EP0534060A1] A method for manufacturing yarn guiding rings, includes a first step of blanking a plate (3) to form a plate body (1) constituted by a supporting element (7) and by a fork element, and a second step of bending the fork in order to obtain a circular ring. The fork element has two arms (5). Each arm is constituted by two portions with different curvatures (R, S). The outer portions of the arms are folded until the curvatures are all identical, producing a circle with radius (R) and overlapping the free ends of the arms. The yarn guiding ring is thus constituted by a single blanked and bent part with a solid cross-section. <IMAGE>
