FIELD: manufacturing technology.
SUBSTANCE: group of inventions relates to pressing device and method for forming recesses in plate. Device comprises pressing head having pressing surface, which is intended for contact with plate, and supporting element. At that, pressing head compresses plate section between pressing surface and supporting element for formation of cavity in plate. Pressing surface comprises sections of first and second surfaces, separated by textured area, which is intended for compression of plate in supporting element direction with smaller compression force in comparison with sections of first and second surfaces. Device also comprises drives to move pressing head and supporting element in first direction, which is, substantially, corresponds to plate movement direction, and in second direction, which is, substantially, perpendicular to plate plane, wherein pressing device speed in first direction, substantially, corresponds to plate speed.
EFFECT: technical result is higher efficiency of pressing and formation of cavities in plate.
