Abstract (en)

[origin: EP0884263A1] A braking device for textile machine weft feeders (14), comprising a frustum-shaped braking body (15), which faces the drum (11) of the weft feeder (10), and an adjustable annular support (16), whereto the frustum-shaped body is rigidly coupled by means of a preloaded elastic suspension (17). According to the invention, and in order to optimize its elastic characteristics, the suspension (17) comprises at least two sets of identical corresponding traction springs which have respective different stiffnesses and preloadings which are inversely proportional to the respective stiffness of the springs. <IMAGE>
