Embodiment Construction
[0060] These figures show some examples of yarn tensioning systems (1) according to the invention.
[0061] Each of these yarn tensioning systems (1) comprises, for each yarn (2) to be tensioned, a rotatably arranged braking roller (5) and a means for supplying the braking roller (5) torque motor (6).
[0062] exist figure 1 In the first embodiment shown, the yarn (2) is withdrawn from the yarn storage system (3) to the yarn delivery system (4) of the loom in a first direction (A), or in a direction (A) A) On the opposite second direction (B) between the braking roller (5) and the yarn output system (4), the yarn (2) is wound several times on the braking roller (5) to limit the yarn (2) Sliding relative to the brake roller (5).
[0063] In order to further limit the sliding of the yarn (2) relative to the braking roller (5), the yarn tensioning system (1) also includes a braking device (7), which is arranged between the yarn storage system (3) and the braking roller (5). b...
