ABSTRACT:
A procedure for splicing textile yarns mechanically whereby two yarns which are initially placed crosswise, awry or parallel to each other are first untwisted and then retwisted together by two rings, the rings being placed face to face and opposite to each other and act on yarns positioned between the rings, and whereby the excessive tail ends are eliminated and the yarns are untwisted up to a desired value in positions of mutual non-interference and are then brought together until they are substantially pressed against each other and are clamped at a position lying at about the beginning of the desired taper of each remaining tail end in cooperation with the rings so as to determine the length of the remaining tail ends and to effect a plucking/tearing action on the tails to be discharged, thereby obtaining progressive remaining tail ends before the retwisting action, and whereby the remaining tail ends are doubled and retwisted at least by the rings, which control the tail ends in at least two points located at least at about the ends of the splice.
A splicer device for splicing textile yarns mechanically having two rings facing each other, whereby at least one ring is movable in relation to the other and two yarns to be spliced are positionable between the rings, and whereby the yarns undergo a controlled untwisting action and a controlled retwisting action and also an intermediate action of removal and discharge of their excessive tail studs to bring the yarns together, an intermediate clamp cooperating with a plucking and tearing element, a retwisting element, and a drive cam.
