METHOD AND DEVICE FOR CORRECTING POSITION OF SLEEVE WHEN SLEEVE IS USED

Japanese Patent JP3756611

B2

PROBLEM TO BE SOLVED: To prevent a deviation or the like of a position of a sleeve when a long-scale synthetic resin-made sheet is continuously molded, for instance, between a molding roller and a molding drum means having the sleeve into contact in a curved shape with a peripheral surface of this molding roller. SOLUTION: By a molding mechanism 10 comprising a molding roller 12 rotatably supported and a molding drum means 13 contact rotated in a circular arc shape partly in a peripheral surface of this molding roller 12 to circulation support a flexible sleeve 14 holding and pressing with the molding roller 12 by paired support rollers 15, from a fused synthetic resin material M, a long- scaled synthetic resin-made sheet S is molded to be conveyed. A jack structural unit 27 is provided, which has an external tread-shaped jack shaft 29 rotated so as to lift by a screw feed a nut unit 8 connected to any one of roller blocks 18 in a right-left side part supporting the support roller 15, and a control unit is provided, which rotates by a prescribed value the jack shaft 29 in a forward/ reverse direction by a detection signal from a fine displacement detection sensor always detecting a side edge position of the sleeve 14.
