Abstract From the Canadian patent

Process for incorporating a metal framework inside a plastic material in order to make moulded articles. The process involves making a thin knitted article (1) preferably with sunk stitches, which is flexible in order to provide deformability and associating said knitted fabric with a plate or sheet of plastic material. This association of the metal knitted fabric (1) is effected immediately at the outlet of the unit forming the sheet or plate of plastic material (2) the association being made by calendering before the formed plate of plastic material has cooled thereby allowing for the incrustation of said knitted structure at least superficially, inside said plate or sheet of plastic …
