Abstract
A process for the pneumatic splicing of threads or yarns containing an elastomer or with a high torque comprises at least the following phases: introduction into a splicing chamber (11, 110) of a splicer (10, 100) of threads (12, 15) to be joined to each other; withholding by friction of the thread-ends (12, 15) by means of friction elements or devices (27, 20, 21) close to or inside the splicing chamber (11, 110); cutting of the thread-ends (12, 15); opening of the thread-ends (12, 15) cut by means of preparation units (22, 23); pulling of the cut and opened thread-ends (12, 15) in the direction of the junction chamber (11, 110); expulsion of the threads and contemporaneous entry of one or more jets of compressed air into the chamber (11, 110) to effect the splicing of the thread-ends (12, 15) and releasing of the spliced thread with the return of all the units of the splicing device (10, 100) to their initial position.
