ABSTRACT:
Disclosed is a laminating machine for applying a protective laminate to the edge of any paper or paperboard product such as an index or paperboard card. The machine includes grippers for retaining opposed edges of a cut laminate and an elongate crimping mechanism for engaging the laminate between the grippers and for pressing the laminate against the nip of a pair of pressure rollers. The elongate crimping mechanism is withdrawn and an edge of the paper or paperboard product is fed to the elongate crimp created in the laminate. The paper and laminate are then fed between heated pressure rollers to effect lamination. The above steps can be repeated to apply a laminate to two or more edges of a paper or paperboard product. When two or more adjacent edges are to be laminated, a cutting mechanism cuts the laminate at angles to form miter joints at the corners.
