Abstract

A pneumatic weft end tension device for air looms provides to keep the free weft yarn end tensioned, after it has been inserted into the shed, thus preventing or promptly damping any longitudinal elastic weft yarn oscillations. The pneumatic weft end tension device consists of a blower (1) inserted between two adjacent blades (6) of the reed - and apt to spread them apart - in a position beyond the split selvedge zone of the fabric being woven. The air stream coming from the blower (1) deviates the free weft yarn end between the two blades (6), spread apart, thereby braking said yarn to an extent sufficient to prevent its elastic oscillation after its insertion has taken place. <IMAGE>
