APPARATUS AND METHOD OF MAKING A PAPER END WITH A SMOOTH CHUCK WALL

摘要

A novel method and apparatus is provided for forming a pressed paper end which minimizes or eliminates deformations in the chuck wall. The method involves using a novel die press apparatus in which, at the very end of the compression stroke, the paper is held tightly by the opposing dies on either side of the chuck wall forming area, and the chuck wall forming area is held in substantial confinement between the dies.
