Abstract
Method and apparatus for lamination of substrates, e.g. rigid plastic layers, to manufacture laminated products. The methods include the sequential application of vacuum and mechanical force through a two-stroke process performed by a lamination apparatus having one or more force-producing stroke cylinders. Actuation of a cylinder to produce a first stroke creates a sealed chamber within the apparatus, enclosing a stack of substrates to be laminated. The sealed chamber may be evacuated of air by application of a vacuum. Subsequent actuation of a cylinder to produce a second stroke applies mechanical force to the sealed chamber, which compresses the substrates into a laminated product substantially free of air bubbles or voids.
