Abstract
The present invention is related to a new process and equipment to produce mesh in non-metallic materials such as leather having a wide application in industrial and commercial fields. The process produces a variety of cuts or incisions in a relatively flat and thin, non-metallic material and then subjecting it to different treatments which include introducing the material into a steam chamber, extruding it, molding it and, if desired, submitting same to a heat treatment in order to keep the shape of the mesh during its practical usage and, if desired, further subjecting same to a final finish.
