Kind Code:
B2
Abstract:
This invention concerns improvements to procedures to splice yarns (20-21), whether textile yarns or otherwise, the splice being obtained by coupling two single untwisted yarns (20-21) and by reconstituting the twists thereafter, by which improvements a part of the single yarns (20-21) is untwisted until twists of a sign opposite to the sign of the original twists have been imparted, such part then being coupled and reduced tails (220-221) of yarns being obtained, the coupled tract then being retwisted until a required twist has been imparted, the improvements envisaging thatthe reduced tails (220-221) are obtained after the fibres to be plucked and/or torn (42) have been made substantially parallel and after a substantially axial plucking and/or tearing action has been applied to such fibres (42), and that the taper (320-321) of the remaining reduced tails (220-221) reachesthe neighbourhood of the periphery of retwister rings (28), the resulting remaining tails (220-221) being controlled and positioned beside the yarns (20-21) before the action to impart the required retwisting is begun.
