ABSTRACT:
To the purpose of obtaining the joining of textile threads, by means of a splice accomplished with compressed gas, by a short, strong joint of nearly imperceptible appearance, a method is proposed, which includes the following steps: inserting the two threads to be joined through a longitudinal slit in a splicing chamber provided in a head having two parallel opposite side walls perpendicular to the longitudinal axis of the chamber, in correspondence of which walls there are side outlets; substantially closing the side outlets of the chamber and at the same time locking the threads entering the chamber through its related side outlets, against the respective side walls of the head, but leaving free and unlocked the cut tails of the thread coming out of the outlets; and subjecting the thread lengths enclosed within the chamber to at least one burst of compressed gas blown into the chamber, the gas escaping through a port provided in the head transversely to the longitudinal axis of the chamber. The device includes a head provided with parallel side walls wherein a splicing chamber is provided with its longitudinal axis perpendicular to the side walls, and opening through the same walls, with a longitudinal slit for the introduction of the threads to be joined into the chamber, and with a transverse slit for the escape of air, as well as elements movable to approach and move away from the respective side walls of the head, to substantially close the outlets of the chamber, and to lock the threads entering the chamber against the respective side walls, but leaving free and unlocked the cut tails of the threads coming out of the chamber. The longitudinal slit may be closed by a cover.
