Metal recovery machine and method of metal removal from metal containing laminates

Abstract

A metal recovery system utilizes a metal recovery machine for metal removal from metal containing laminates, such as polymer films containing a layer of metal. A laminate may include a metal layer on a backing. The laminate may be stretched while being heated to cause the metal layer to separate from the backing and form cracks that aid in the separation of the metal from the backing. The laminate may be passed through an inlet roller into a heater, such as an oven, before passing over an outlet roller. The outlet roller may have a higher speed imparted on the laminate than the inlet roller, thereby causing the laminate to stretch while being heated by the heater. Metal removal devices such as brushes and a vacuum may be used to remove metal from the laminate.
