ABSTRACT:
The thread braking device comprises a pair of braking members, which are arranged symmetrically in respect to the path of the thread. Each of the braking members has a spring member. Between these spring members a line-shaped, vertically arranged braking zone is defined. For braking, the spring members are pivoted on rockers towards the thread path. Due to this movement as well as due to the vertical arrangement of the spring members, the deposition of contaminations in the braking zone is avoided. The elasticity of the spring members reduces the danger of damage in the presence of thickened thread sections.
