METHOD OF MAKING BOTTOMS WITH VARIOUS DIMENSIONS BY PRESSING

摘要

The principle of this method consists in the fact that at first two initial semi-products are positioned on each other in a die block. Their cumulative thickness, enlarged for a total of their packing, is identical with a pressing clearance of the die block. These semi-products are mutually turned towards each other. When the bottoms are pressed, each inner bottom is separated from the outer one by cooling.<IMAGE>
