Abstract An automatic laminator for the lamination of sheet-form product wherein lamination occurs automatically upon the introduction of the product to a nip and a laminating apparatus and in which lamination discontinues upon passage of the product through the nip. Adjustment means are provided preventing movement of the laminating film through the laminating nip except under circumstances in which the product to be laminated is present in the nip.
