Abstract
An anti-balloon device, to be placed downstream of a weft feeder for weaving looms, comprising a structure which forms a substantially tubular through cavity, preferably substantially frustum-shaped; the cavity is crossed by an unwinding thread that arrives from the weft feeder and controls the passage of the thread, by opposing the centrifugal force that affects it. The structure is shaped like a bottomless basket which is formed by rods lying longitudinally between end elements which connect the rods; the end elements are end rings which are mutually angularly spaced so as to surround the cavity in order to control the passage of the thread.
