Abstract:
A device (10), for the pneumatic splicing of threads or yarns, including one splice box (11), equipped with lateral outlet edges (12, 13) and with an upper lengthwise slot (30), through which said thread ends (14, 15) are introduced into said splice box (11) and through which pressurized air is blown into said splice box (11), further comprising means to partially close and open said 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 said splice box (11) when said lateral outlet edges (12, 13) are partially closed, and a second introduction of at least one blast of compressed air into said splice box (11) when the lateral outlet edges (12, 13) are completely open; wherein the means to open and close said lateral outlet edges (12, 13) of the splice box (11) has an arm (19), which is rotary operated and ends in two rods (24, 25) that intercept, at least partially, said lateral outlet edges (12, 13).
