METHOD OF MANUFACTURING GLASS PRODUCT AND GLASS PRODUCT CONTAINING A PLURALITY OF COLOR STREAK PATTERNS OR BUBBLE STREAK PATTERNS

摘要

PROBLEM TO BE SOLVED: To improve the thickness distribution of products in forming a piece of the product with a plurality of gobs and to automatically form the products having a plurality of intersected color streaks.;SOLUTION: In the manufacturing method of manufacturing a piece of the product from the plurality of gobs with the manufacturing apparatus for the glass products to be automatically produced, the gobs are formed by changing the angle in the plane direction of the second and subsequent gobs or the disk gobs with respect to the direction of the first gob or the disk gob formed by once pressing the gob, by which the temperature distribution of the gobs and the disk gobs before the forming is improved and the thickness distribution of the products is made more uniform. The formation of patterns, such as color streaks and bubbles streaks of cruciform shapes, etc., intersecting with each other is made possible.;COPYRIGHT: (C)2002,JPO
