Abstract (en)
[origin: EP1319623A1] The procedure consists of taking the end (3) of the yarn and inserting it under tension in the extension of the last wound coil. A slack loop is made parallel to the end of the yarn and twisted together with the yarn. The twist is fastened to the bobbin (1) and the remaining end of the yarn is trimmed off. <??>The pick-up unit (5) for the free end (3) of the yarn is preferably in the form of a suction nozzle (9) with an inner permeable retaining member in the form of a fine grille or foam, a detector cell, and a movable positioning plate (10). The loop is made by a deployable element (11) with rods (12).
