PRODUCTION OF LONG CERAMIC AND CURVE CORRECTION DEVICE FOR LONG CERAMIC

Title:

PRODUCTION OF LONG CERAMIC AND CURVE CORRECTION DEVICE FOR LONG CERAMIC

Document Type and Number:

Japanese Patent JP2632770

Kind Code:

B2

Abstract:

PURPOSE: To straightly correct the center axis of an extruded material under the own wt. of the material after a material drying process.
CONSTITUTION: A columnar or cylindrical extruded material W after a material drying process is placed on a plurality of correction rollers 19. When a drive motor 20 is driven, the correction rollers 19 are rotated by the rotation of a rotary shaft 17 and the extruded material W is also rotated. As the columnar or cylindrical extruded material W not yet losing plasticity is rotated, the curve of the material W is corrected under the wt. of the material W itself to obtain the extruded material W having a straight center axis.
