Abstract: A multi-station press is provided with a press transfer device that engages articles at the press stations after processing and transfers the articles to the next station before the press performs its next press cycle. The press transfer device includes a pair of elongated transfer bars extending along the transfer directions of the press, and grippers or other article engaging elements mounted along the transfer bars to engage the articles for transfer. The transfer bars are moved together by a grip moving unit to engage the articles, the transfer bars are lifted by a lifter, the transfer bars are then moved endwise by an endwise moving unit to the next press station. The lifter then lowers the bars and the grip moving unit moves the bars apart to disengage the articles, thereby leaving the articles at the next station. The grip moving unit ensures that the transfer bars are moved far enough apart so as not to interfere with the press during the next press cycle.

Abstract: 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.

Abstract: A simple combination of conventional operations uses a twin press configuration of tandem stationary, vertically acting heating and cooling platen presses in separate frames of a laminating machine which is loaded by rollingly transferring a book into the heating press in either of two loading-paths. One is at right angles to the path in which the book is to be processed ("process-path") so as to avoid using an entrance station. The other uses an entrance station which provides a loading-path parallel to the processing path through daylight openings ("daylights") in the presses, so as to support each book on the edge-conveyor means while it is stationary and coplanar with the loading-path. The system operates with a minimum cycle time based on the physical properties of the sheets to be laminated.
