Abstract
A device for the pneumatic splicing of threads or yarns which includes a splice box (11), equipped with lateral outlet edges (12, 13) and an upper lengthwise slot (30) through which the thread ends (14, 15) are introduced into the splice box (11) and into which it is possible to blow in pressurized air. The device includes means to open and close, at least partially, the lateral outlet edges (12, 13) so as to be able to carry out an initial introduction of at least one blast of compressed air into the splice box (11) when the lateral outlet edges (12, 13) are mostly closed, and a second introduction of at least one blast of compressed air into the splice box (11) when the lateral outlet edges (12, 13) are mostly or completely open. Besides, the present invention has, as its aim, a process for the pneumatic splicing of threads or yarns.
