Abstract
A weft length measuring device comprising a weft storage drum supported against rotation and a weft winding member rotatable around the drum to wind a weft thereon is disclosed. According to this invention, the measuring device further comprises a length measuring control or retaining pin and a weft unwinding control pin arranged a pair at axially spaced positions in the weft storage drum and operated by a cam mechanism so as to alternately project out of the weft storage drum at appropriate times in the weft inserting cycle, and a weft transfer member arranged on the outer periphery of the weft storage drum to cause the weft for one weft insertion, the length of which has been measured by the rearwardly disposed rearward, length measuring pin, to be transferred toward the forward, weft unwinding control pin. During the weft inserting operation during which the weft wound on the drum is unwound, a succeeding weft for the next weft insertion can be continuously and exactly wound on the storage drum.
