摘要

The brake for a running yarn/ribbon (1) has at least one guide body (2) and at least one brake body with a flexible cushion (3) which can be filled with a fluid. A system generates and controls the fluid pressure in the cushion. The brake for a running yarn/ribbon has at least one flexible cushion, which is operated by the brake body. At least one cushion can also be the brake body, and it has a replaceable and flexible mantle shrouding on the braking side. The guide body has a guide groove to take the moving yarn/ribbon. The cushion is held by a support (4), on the side away from the moving yarn/ribbon, and it can be fixed to the support. The brake pressure applied to the moving yarn/ribbon is set according to its registered tension. One cushion can apply a braking action to at least two running yarns/ribbons.
