Patent attributes
This invention concerns a weft thread clamp with two jaws (1), (2) that can be moved to an opened and closed position, with at least one jaw (1) being directly moveable to the closed position via fluid pressure. The moveable jaw is preferably (1) a moveable unit, preferably made of a light material or in a compact form, which is moveable as a complete unit under the influence of the fluid pressure. Such a weft thread clamp is more reliable and simpler, and has a quicker reaction speed than the known pneumatically controllable weft thread clamps. This invention also concerns a system for the presentation of weft threads to a weaving machine equipped with one or more such weft thread clamps, as well as a weaving machine equipped with such a presentation system.
