Abstract
Abstract A coated substrate is produced by pressing a solid mass of an organic coating composition against a traveling metal carrier such as an endless metal belt, heating only that part of the coating composition mass adjacent to and contiguous with the carrier to that degree necessary to liquify the coating composition and cause a coating to form and deposit on the carrier, laminating a substrate to the coating, and then removing the resulting coated substrate from the carrier. A three-layered laminate having the coating centrally located is produced by laminating a second substrate to the coated side of the coated substrate.

Claim 12
Independent Claim
178 words
An apparatus for producing a coated substrate having a coating derived from a solid organic coating composition which comprises: a supported metal carrier adapted for travel; means for moving the carrier in a predetermined direction of travel; means for holding and feeding a mass of the solid organic coating composition in contact with a surface of the carrier; pressure means associated with the holding and feeding means, for pressing the mass of the coating composition against the surface of the carrier, said pressure means being nonrotatable; heating means for liquifying essentially only that part of the mass of the coating composition contiguous with and adjacent to the surface of the carrier so that passage of the carrier against the liquified part of the mass produces a smear coating thereof on the surface of the carrier; means, downstream the direction of travel from the holding and feeding means, for laminating a substrate to the coating to produce a coated substrate; means, downstream the direction of carrier travel from the laminating means, for removing the coated substrate from the carrier.
Claim 13
Dependent Claim
127 words
The apparatus of claim 13 adapted to produce a laminated product from the coated substrate which further includes: a second carrier, adapted for movement, disposed downstream from the coated substrate removing means and so associated with the metal carrier as to receive and carry the coated substrate with the smear coating layer exposed; means, associated with the second carrier, for reactivating the smear coating layer to render it adhesive to a second substrate; means, associated with the second carrier downstream its direction of movement from the reactivating means, for laminating the second substrate to the smear coating layer to form a laminated product; means, associated with the second carrier downstream its direction of movement from the laminating means, for removing the laminated product from the second carrier.
