PURPOSE:To enable the optimum press welding in accordance with the thickness of resin for sure adhesion of a metal plate and the resin, by providing cooling nozzles arranged in the widthwise direction of a press welding roll each with a roll displacement measuring instrument and a coolant supply pipe. CONSTITUTION:The optimum roll shape corresponding to the resin thickness is prestored into an adjuster 7 to set the resin thickness; thereby, control valves 8, 8a-8d of coolant supply pipes 6, 6a-6d are controlled as to make a roll shape corresponding to this resin thickness, and coolant is sprayed to the surface of heat press welding roll 1 from nozzle holes of cooling nozzle 4, 4a-4d. On the other hand, the roll shape is inputted from measuring instruments 5, 5a-5d into the adjuster 7, resulting in cooling of the heat press welding roll 1 up to the optimum shape. For example, in the case of recessing the roll center, coolant spray of both-end nozzles 4, 4d is stopped, and coolant is sprayed from the central nozzles 4a-4c to bond metal plates 2 and 2a under the optimum welding force.
