Abstract
A machine for producing pile fabric comprises a sonotrode (1) , a matrix (4) of tubes (5) bringing threads (10) onto a support sheet (7) for the purpose of welding rows of loops to the surface of this sheet. The matrix (4) is guided between slides (6) which are parallel to the longitudinal axes of the tubes (5) and perpendicularly to the surface of application of the sonotrode (1) vibrations. A driving mechanism (13, 14, 15) periodically brings the extremities of the tubes (5) from which the threads leave against the sonotrode (1) by pressing the base of a row of loops and the support sheet (7) against the sonotrode in order to cause them to be welded together.
