Abstract
The present invention concerns a machine for continuously crimping textile threads. The machine (10) comprises a frame composed of a support plate (14) to which there are attached two upper blocks (17a and 17b) defining a compression chamber (18), two elements (19a and 19b) defining a decompression chamber (20) and two paddles (21a and 21b) defining an evacuation chamber (22). The threads are introduced into the compression chamber by two pulleys (25a and 25b). The decompression chamber (20) is supplied with steam through conduits (31a and 31b). The paddles (21a and 21b) are subject to the action of two spring blocks (33a and 33b). This machine is used to cause crimping and bulking of all kinds of threads, and for fixing the crimping and inflation.
