Abstract: A device (10, 10′) for the splicing of textile threads using compressed air and liquid, which includes a casing on which is assembled a splicing head in which is made a mixing chamber (11), at least one feed duct of air with added liquid which leads into the chamber (11), a valve which is controlled by the immission of compressed air and means to add the liquid to the compressed air before its immission into the chamber (11). The splicing head, with its chamber, is set in an isolated tank from which extends at least one channel for the discharge to the outside of the compressed air with added liquid device. The device (10, 10′) has means for creating suction in the water discharge channel or channels (15, 16, 22, 23). In addition, the object of the present invention is a process for the splicing of textile threads using compressed air and liquid.

Abstract: A device for preparing a thread end for splicing with an apparatus for the knotless pneumatic splicing of textile threads and yarns comprises a small tube for treating the thread end which is open at its opposite ends and suitable for receiving the end of the thread to be treated in correspondence with a peripheral point of its inlet end, and, at a distance from and opposite the said inlet end of the small tube, a circular nozzle for blowing a jet of pressurized fluid which is aligned with the said small tube and may be connected to a source of compressed fluid, the said nozzle having the end from which the jet of fluid emerges cut obliquely with respect to its axis so as to form an elliptical aperture and being mounted in rotatably adjustable manner about its axis with the elliptical outlet aperture of the jet of fluid facing towards the peripheral point of the inlet end of the small tube in correspondence with which the latter receives the thread end to be treated.
