Abstract
Abstract A method of manufacturing a goods of laminated materials which comprises the steps of wetting with a solvent one face of a first layer of a base material, of applying on to said face a second layer of pre-expanded pellets of a plastic, and of injecting and expanding directly on said second layer a third layer of a plastic.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
61 words
A method of manufacturing a goods of laminated materials characterized in that it comprises the following steps: (a) wetting with a solvent one face of a first layer of a base material; (b) applying onto said face a second layer of pre-expanded pellets of a plastic; and (c) injecting and expanding directly on said second layer a third layer of plastic.
Claim 2
Independent Claim
61 words
A method of manufacturing a goods of laminated materials characterized in that it comprises the following steps: (a) wetting with a solvent one face of a first layer of a base material; (b) applying onto said face a second layer of pre-expanded pellets of a plastic; and (c) injecting and expanding directly on said second layer a third layer of plastic.
Claim 3
Independent Claim
67 words
A method of manufacturing goods of laminated materials comprising: applying to one face of a first layer of a base material a sheet of decorative material; wetting with a solvent the opposite face of said first layer; thereafter applying onto said wetted face a second layer of pre-expanded pellets of a plastic; and thereafter injecting and expanding directly on said second layer a third layer of plastic.
Claim 4
Independent Claim
67 words
A method of manufacturing goods of laminated materials comprising: applying to one face of a first layer of a base material a sheet of decorative material; wetting with a solvent the opposite face of said first layer; thereafter applying onto said wetted face a second layer of pre-expanded pellets of a plastic; and thereafter injecting and expanding directly on said second layer a third layer of plastic.
Claim 5
Independent Claim
57 words
A method of manufacturing goods of laminated materials comprising: wetting with a solvent one face of a first layer of a base material; applying onto said face a second layer of pre-expanded pellets of a plastic; and injecting and expanding directly on said second layer a third layer of plastic in which there is embedded a reinforcement.
Claim 6
Independent Claim
57 words
A method of manufacturing goods of laminated materials comprising: wetting with a solvent one face of a first layer of a base material; applying onto said face a second layer of pre-expanded pellets of a plastic; and injecting and expanding directly on said second layer a third layer of plastic in which there is embedded a reinforcement.
Claim 7
Independent Claim
54 words
A method of manufacturing goods of laminated materials comprising wetting with a solvent one face of each of two layers of a base material; applying onto each wetted face a second layer of pre-expanded pellets of a plastic; and injecting and expanding a third layer of plastic directly on and between said second layers.
Claim 8
Independent Claim
54 words
A method of manufacturing goods of laminated materials comprising wetting with a solvent one face of each of two layers of a base material; applying onto each wetted face a second layer of pre-expanded pellets of a plastic; and injecting and expanding a third layer of plastic directly on and between said second layers.
Claim 9
Dependent Claim
10 words
A laminated article manufactured by the method of claim 1.
Claim 10
Dependent Claim
10 words
A laminated article manufactured by the method of claim 2.
Claim 11
Dependent Claim
10 words
A laminated article manufactured by the method of claim 3.
Claim 12
Dependent Claim
10 words
A laminated article manufactured by the method of claim 4.
Claim 13
Dependent Claim
144 words
In a method of manufacturing a laminated construction panel by injecting and expanding a plastic material onto a face of a base layer in a mold, the improvement which comprises improving the bond obtained between the base layer and the injected, expanded layer by wetting said face of said base layer, before the injection and expansion step, with a liquid volatile solvent, applying onto said wetted face a layer of pre-expanded pellets of a plastic thereby partially dissolving the pellets so as to cause them to stick to said base layer, evaporating the solvent through the interstices between the pellets and thereafter carrying out the injecting and expanding of said plastic material on the layer of pre-expanded beads, said plastic material being compatible with said beads thereby achieving a stable and durable bond between the injected and expanded plastic material and said base layer.
