Abstract

Yarn feeder, especially to feed the weft yarn to gripper or projectile looms, wherein the weft yarn is unwound from a weft yarn reserve wound on a drum, onto the outlet end of which there acts a yarn braking device upstream of an outlet yarn guide. The yarn braking device, centered on the drum axis and adjustable along the drum, comprises a frustoconical braking element having a continuous surface and varying flexibility, especially along its generating lines. The yarn braking device is carried by a stiff ring support to which it is fixed close to its major circumference. The support is in turn fixedly mounted onto a bracket of the yarn feeder, the position of which is adjustable along the drum axis.
