Abstract:
1. A method for producing a foamed article including a supporting element, a foam layer, and an upholstery cover applied on said foam layer, comprising the steps of: forming said upholstery cover by stitching together a plurality of lengths of upholstery cover, positioning the sewn upholstery cover on a convex positioning surface of a positioning member, withholding the sewn upholstery cover on said positioning member by means of a first suction system, setting said positioning member with the sewn upholstery cover withheld thereon by suction in a bottom die of a foaming die, deactivating said first suction system and withholding the upholstery cover on a concave positioning surface of said bottom die by means of a second suction system, extracting said positioning member from said bottom die leaving said upholstery cover positioned and withheld by suction on said concave positioning surface, positioning a rigid supporting element on a plunger of said foaming die and closing the plunger on said bottom die so as to form a foaming cavity between an outer surface of said supporting element and said upholstery cover, and injecting foaming material into said foaming cavity and polymerizing the foaming material.
