"Process for retention of a weft thread; the value chain with a set of clamping for the weft thread, especially for the implementation of the procedure.And the cartridge as a unit construu00ecda interchangeable for integration in the tube mixer of a chain. The present invention relates to a chain, the number of grip (1) for the weft thread (2) integrated between the two segments of the tube mixer (5, 6).By means of the housing (10) is formed in a chamber (9), in which is located the muscle (15) pneumatic or hydraulic, with two clamping pieces (4a, b) similar to the blades, whose free ends (8a,(b) points in the direction of the introduction (7) of the weft thread. All tube mixer (3) is located behind an injector is not represented.The chamber (9) is followed by a connecting means of pressurisation (16) which by means of pressurisation lines (19, 20), and a valve means (17) is united with a pressure source (18).The position represented the valve means (17) is exerted on the muscle pneumatic or hydraulic (15), so that the free ends (8a,(b) the clamping parts like blades (4a, b) move inside, and arrested the weft thread (2).It is also planned to a piezo electric or magnetic control of clamping pieces similar to blades (4a, b).
