Abstract
One purpose of this invention is to produce, through the extrusion of a thermoplastic substance, bands or tubes of double fabric which are generated through the simultaneous extrusion of two or more fabrics, one on top of the other, fastening them both together in the same continuous operation. One of the peculiarities of this invention is that, in fastening the fabrics together, at certain crossing points the threads are fixed (welded) together whilst, alternately, at other crossing points the threads remain free (without fastening, fusion or welding) at the level of each mesh. Another purpose of this invention is to provide a device for putting the invention into practice, enabling the simultaneous extrusion of two or more fabrics, one on top of the other, and (in the same continuous operation) causing the component fabrics to fasten together to form the double fabric.
