Abstract (en)

[origin: WO2018231063A2] A method of forming a flexible loop (6") comprising one or more continuous flexible strands (1), comprises coiling the strand (1) upon itself multiple revolutions (R) to form a plurality of coils (1b) which collectively form a bundle (23) of a predetermined thickness (t1); and for each revolution (R), passing the strand (1) around an imaginary centre line CL at least once so as to form a twisted bundle (23). In one embodiment, the method comprises forming a mantle (18) applying a stitching procedure. A strand (1) winding apparatus (8), comprises a ring member (11) rotatably arranged in a body (12), said body(12) having a tubular ring shape dimensioned such that the ring member (11) may rotate (R) inside said body; said body comprising a helical slit (9). A plurality of strand guides (10) having a strand-conveying member (10c) fixedly connected to the ring member (11) extend through the slit (9) and comprise at least one strand-conveying member (10c). A chain may be formed by interconnecting a plurality of the flexible loop.
