A simple combination of conventional operations uses a twin press configuration of tandem stationary, vertically acting heating and cooling platen presses in separate frames which share a fixed, hybrid bottom platen in a laminating machine. The machine therefore has aligned daylight openings ("daylights"). A set of sheets to be laminated is sandwiched between cover plates of a book which is loaded by rollingly transferring it with an edge-conveyor means, into the heating press. The path in which the book is processed ("process-path") starts at an entrance station and progresses linearly through the daylights. The system operates with a minimum cycle time based on the physical properties of the sheets to be laminated. Successive books may be loaded, in a machine using only two single daylight openings; or, in ganged single daylights; depending upon the capacity per unit time sought. A novel quick-locking carrier is provided in which a sandwich to be laminated is held.
