PCT No. PCT/CH82/00125 Sec. 371 Date Aug. 3, 1983 Sec. 102(e) Date Aug. 3, 1983 PCT Filed Dec. 1, 1982 PCT Pub. No. WO83/01966 PCT Pub. Date Jun. 9, 1983.This machine 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.
