Anti-balloon device for weft feeders for weaving looms, particularly air jet looms

摘要

An anti-balloon device (10), to be placed downstream of a weft feeder for weaving looms or the like and particularly downstream of a premeasuring weft feeder (1) for air jet looms, comprising a structure (10) which forms a substantially tubular through cavity, preferably substantially frustum-shaped and suitable to be crossed by an unwinding thread (F) that arrives from the weft feeder (1) and suitable to control the passage of the thread, by opposing the centrifugal force that affects it. According to the invention, the structure (10) is shaped like a bottomless basket which is formed by rods (11) lying longitudinally between end elements which connect the rods, typically end rings (12-13) which are mutually angularly spaced so as to surround the cavity in order to control the passage of the thread (F).
