1. An intermediate processing method of an extrusion-molded resin sheet for manufacturing a plurality of intermediate resin sheets, each of which is to be subjected to a heat press processing, from an extrusion-molded resin strip that has been heated and extrusion-molded, the intermediate processing being a processing after the extrusion molding and before the heat press processing, comprising the steps of:
virtually segmenting the extrusion-molded resin strip into a plurality of individual areas corresponding to the plurality of intermediate resin sheets;
virtually segmenting each of the individual areas into a plurality of segmented areas;
acquiring curvature related information from a storage device, the curvature related information being related to a curvature of each of the segmented areas for each of the individual areas that is expected to occur as a result of the heat press processing;
setting a coating condition of a coating device for each of the segmented areas based on the curvature related information for each of the segmented areas that was acquired from the storage device; and
controlling the coating device to coat a coating on each of the segmented areas of each of the individual areas, based on the coating condition that was set for each of the segmented areas.
