  • Preparation of laminated sheets
    Patent number: 5824178
    Abstract: A process for making a laminated sheet by cutting a fiber-reinforced thermoplastic resin sheet into a plurality of cut sheets. The cut sheets are feed to a butting apparatus to bring adjacent end faces of the cut sheets against each other. The abutted cut sheets are joined to a continuous sheet, which is a fiber-reinforced thermoplastic resin sheet, by melt welding using a heated roller where the cut sheets and the continuous sheet cling to the heated roller. Cooling of the joined cut sheets and continuous sheet occurs by causing such to cling to a cooling roller. A correcting roller is moved along the cooling roller, where the joined cut sheets and continuous sheet are between the cooling roller and the correcting roller, so that the amount of contact arc between the joined cut sheets and continuous sheet is changed to adjust the amount of warp in the joined cut sheets and continuous sheet.
