  • Patent number: 5073076
    Abstract: A device for simultaneously or sequentially edge binding a sheaf of papers and separately laminating single sheets. A heat applying assembly includes a body of heat conducting material having a generally horizontal elongated slot extending through the body and two pairs of rollers, one at an input end of the slot and the other at an output end thereof for feeding a document between two thermoplastic sheets through the slot. Upper and lower imbedded heating coils apply heat above and below the slot for fusing the thermoplastic sheets to effect lamination of the document. The body of heat conducting material provides an upper surface slanted at an acute angle with respect to the horizontal. A rigid guide surface oriented by an equal angle with respect to the vertical provides for gravity retention of a sheaf of paper to be edge bound against the aforementioned upper surface, a heat setting adhesive being introduced along the common end of tyhe sheaf of papers thereby binding the papers along a spine.
