Abstract:
A method for production of a layered product having at least two layers, a first primary layer and a second layer of mouldable material, comprising the steps of:providing a continuous supply of a primary layer material to a plurality of moulding cavities arranged in an endless loop; creating a vacuum between said primary layer material and said moulding cavities to draw the primary layer material into contact with walls of said moulding cavities; dispensing a metered supply of said mouldable material to said plurality of moulding cavities on said primary layer using a dispenser positioned in communication with said moulding cavities, a surplus of said mouldable material located on an outer surface of said endless loop being distributed with said dispenser into a subsequent molding cavity by scraping; and heating the walls of the moulding cavities to a temperature adequate to relax the material of the first primary layer and to maintain a shape given by the moulding cavities.
