Self-adjusting braking device for weft feeders

   
   

A self-adjusting braking device for weft feeders, comprising a frustum-shaped braking body that acts on a thread, is suspended elastically in front of the drum of the feeder and is pushed into elastic tangent contact with the drum along an exit circumference of the drum. The braking body has, at a larger-diameter region thereof designed to make contact with the drum, a discontinuous annular contact element, with a plurality of through slits which are arranged so as to be equidistant and delimit a row of contact laminas.

Un sistema de frenado autoajustable para los alimentadores weft, abarcando a un cuerpo que frena tronco-formado que actúa en un hilo de rosca, se suspende elástico delante del tambor del alimentador y se empuja en el contacto elástico de la tangente con el tambor a lo largo de una circunferencia de la salida del tambor. El cuerpo que frena tiene, en una región del grande-dia'metro de eso diseñada para hacer el contacto con el tambor, un elemento anular discontinuo del contacto, con una pluralidad de rajas directas que se arreglen para ser equidistantes y delimitar una fila de los laminas del contacto.
