Abstract (en)
A weft braking device comprises an axially symmetrical concave body (16) which is pushed with its internal surface against the delivery edge (12a) of the drum (12) of an accumulator yarn feeder. A wear-resistant lamina (20), which has a concave annular profile delimited between an internal annular edge (20a) and an external annular edge (20b), covers an internal annular surface (S) of the concave body (16) in the region in which it abuts against the drum (12). The concave body (16) has a series of slits (22) which are arranged along a circumference thereof, and the wear-resistant lamina (20) has a series of fins (24) which project from the external annular edge (20b) thereof and can be inserted into the slits (22). The wear-resistant lamina (20) is made of a flexible material having a thickness such that it can be initially applied to the concave body (16) with an opposite concavity with respect thereto, and then turned inside out with matching concavity.
