Abstract
Weft thread storage means for a shuttleless web weaving machine includes weft thread supply means for each weft thread and at least one weft thread storage device. Each storage device comprises at least one pivotably mounted storage lever and control means to control each storage device in timed co-ordination with the operation of weft thread feed means of the machine. The control means comprises rotatable cam means respectively associated with each storage device to pivotably displace, before the start of each weft feed, the storage levers of the respective storage device from a first position to a second position, thereby to withdraw a predetermined length of each weft thread from its respective supply means. The storage levers are latched in their respective second positions to store the predetermined lengths of weft thread. Each weft thread is clamped before withdrawal from the supply means and the clamping means in each storage device is released, together with the lever latching mechanism, by releasing means co-ordinated with the operation of the weft feed means of the machine. On being released, each weft thread is fed from the storage device at substantially constant thread…
