ABSTRACT:
A method and apparatus for laminating a plurality of plastic layers together is disclosed in which the lamination is carried out under heat and pressure with at least all but one of the layers being gas permeable in order that any gases within or between layers may be vented to the atmosphere during lamination under said heat and pressure. If desired, all of the layers may be gas permeable. One or more of the gas permeable layers may be plastic powder which meets and consolidates into a continuous, integrated ply during lamination.
