A device for jointing, by means of compressed air, textile yarns and for preliminarily preparing the ends of the yarns to be jointed is provided, in particular for being installed on textile machinery, such as spoolers. In order to achieve minimum overall dimensions of the device, and to the purpose of constructing it in a simple and cheap way, the device comprises a central body (10, 11, 12) bearing a head (26) in which a mixing chamber (27) is provided, two walls (15, 16) positioned opposed to each other and spaced apart from the two outside surfaces of the body perpendicular to the axis of the chamber (27), and two contoured plates (21, 22), with profiled slots (78, 79) slidingly assembled between the outside surfaces of the central body, and the relevant spaced apart wall. The plates (21, 22) are driven to perform linear movements and drive, by means of their slots, the synchronous movements of the moving gears of the device (FIG. 2).

Pneumatic splicer for textile yarns

The invention relates to an apparatus for splicing textile threads by means of compressed air in a mixing chamber, with a device for pretreating the ends of the threads which comprises nozzles controllably feedable with compressed air and arranged at the sides of the body in which the mixing chamber is defined. The jets of air caused to leave the nozzles interfere with the cut ends of the threads laterally leaving the mixing chamber and cause them to be subjected to flapping and to a free whipping for opening and separating the fibres and putting the latter parallel to each other. A whirling motion may be imparted to the jets of air to remove the original twist from the fibres.
