DEVICE AND METHOD FOR PRESSURIZING OBJECT TO BE PRESSURIZED, METHOD FOR JOINING WORKPIECE, AND METHOD FOR PRODUCING ABSORPTIVE ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a device for pressurizing an object to be pressurized, capable of flexibly and economically changing a configuration of a press roll in accordance with a dimension and a shape of the object to be pressurized having a thickness difference.SOLUTION: A device for pressurizing an objects to be pressurized pressurizes the object to be pressurized having a thickness difference in portions to be pressurized by using a press roll 13. The press roll 13 includes a plurality of rolls 14 and 15 different in diameter along a shaft direction X thereof. In the plurality of roll 14 and 15, the ones disposed facing portions having a smaller thickness of the object to be pressurized have a relatively larger diameter, and the ones disposed facing portions having a larger thickness have a relatively small diameter. Also, the press roll 13 has a shaft center and the plurality of rolls 14 and 15 are movably attached to the shaft center.
