Method for producing a plate-like body attached with a resin frame

A method for producing a plate-like body attached with a resin frame in a continuous process, wherein a molded product is formed by extruding through a molding die a resin material for a resin frame into a predetermined shape in cross section;

• the molded product is pushed to at least one surface of a peripheral portion of the plate-like body for a window, and the resin frame having a lip portion for sealing the space between the plate-like body and a window opening to which the plate-like body is attached is integrated with the peripheral portion of the plate-like body, the method for producing a plate-like body attached with a resin frame being characterized by comprising:
• using a thermoplastic elastomer as a resin material for the frame, and
• conducting an extrusion process for extruding the resin material for a resin frame through a molding die to form a molded product;
• a cooling process for cooling the formed molded product to not more than 100° C.;
• a heating process for separately heating a lip portion, an attached surface to be attached to the plate-like body, of the molded product, and the surface of the molded product which is opposite to the attached surface so that the temperature TL of the lip portion, the temperature TA of the attached surface and the temperature TO of the surface opposite to the attached surface have relations of TO<TL<TA and TA≧200° C., and a press-bonding process for putting the molded product into a cavity portion in a pressing member disposed at a predetermined distance apart from the molding die;
• inserting a peripheral portion of the plate-like body into a plate-like body insertion opening of the pressing member, and press-bonding the molded product to the peripheral portion of the plate-like body while the pressing member is moved relatively to the plate-like body along the peripheral portion of the plate-like body, wherein these processes are conducted in the order of the extrusion process—cooling process—heating process—press—bonding process, whereby the resin frame is formed in a continuous process integrally with the peripheral portion of the plate-like body.
