摘要

Improvements in devices for the union without additional twisting of two yarns, at least one of which is not twisted on itself, said yarns being even finest and smooth, that is continuous as those made in synthetic resins, particularly polyamide, polyesters and similar, characterized by comprising two fixed coils, of which the yarn develops in the axial direction, for example from bottom to top; suitable means for passing axially inside the first reel, or respectively from top to bottom, the first spinning, that is to say the one coming from the first reel, and suitable organs for spinning the ball around the first reel, passing respectively from top to bottom , the second yarn from the second reel, joining the two yarns by means of joining members under the first reel, when it is desired that the two yarns without their own twist be joined without additional twisting; suitable organs to pass axially inside the first reel, or respectively from top to bottom, the first spinning and successively, after passing through the joining members, to make it pass to the outside making it turn to the ball, respectively from bottom to top, joining it to the second spinning, also rotated by ball around the first reel, respectively from bottom to top, when one of the yarns is desired to have no torsion of its own and the other has a double twist, said joining members being such that the centrifugal force requesting the two yarns to join tends, as the speed increases, to separate them from the organs themselves, decreasing their resistance to friction by friction in order to avoid the breakage of the yarns themselves.
