Abstract
A method and device for continuously or discontinuously manufacturing flat sheets of multiple-layer materials, laminates, or similar articles for use in the furniture and electrical industries. In order to prevent molten resin from leaking out at the edges of layer of material while they are being bonded under heat and pressure, the free edges of the stacked layers of bonding material are welded together before the material is transformed into a composite sheet or composite web by heat and pressure.
