A process for manufacturing a multilayered object by molding having the steps of positioning a sheet of thermoplastic or textile material in a mold, injecting thermoplastic resin under the sheet, and forming the object by compressing the sheet and the resin. A screen is interposed between the sheet and the thermoplastic resin. The permeability of the sheet is a function of the resin and of the compression. An incision of the sheet is formed in the area of the outer face of the sheet.

A process for manufacturing a multilayered object by moulding, the object having an outer face bearing at least one generally hollow or raised deformed area, the process comprising the steps of: clamping a sheet of thermoplastic or textile material in a mould, said sheet having at least one predetermined region corresponding to the deformed area, said sheet having an incision at such predetermined region; positioning a screen in the predetermined region against said sheet; injecting a thermoplastic resin onto said screen and said sheet, said screen interposed between said sheet and said thermoplastic resin; applying a compressive force to the thermoplastic resin and said sheet in the mould so as to form the object, said screen having a permeability which is a function of the thermoplastic resin and of the compressive force supplied.
