ABSTRACT:
A system is disclosed for laminating surfacing materials, such as high and low pressure laminates, paper, wood veneers, metal foils and the like to core material, such as plywood, particle board, flake board, hard board, rigid plastic foams and the like.
The disclosure includes a machine and a method of laminating, particularly utilizing high viscosity, hot melt adhesives. A sandwich is formed at ambient temperature with the adhesive between the laminate and core either as sheet material or precoated on the laminate or the core. The method employs a progressive heating of the adhesive and adjacent parts of the sandwich from ambient temperature through tackiness to an activating temperature followed immediately by a physical migration of the adhesive to wet out adjacent surfaces followed by a cooling of the sandwich to a mechanical bonding adhesive temperature. The machine is particularly useful in installations for laminating wherein it is desired to avoid the difficulties of melting and applying hot melt adhesives and controlling the necessary conditions thereof.
