Abstract

PURPOSE: To make fine adjustment of overall balance of slip in resistance by arranging many scattering grooves for circular beads on a blank holder plate and insertion and removal free beads stood on the grooves according to the form of drawing of the object product and the cause of occurrence of folds.
CONSTITUTION: Many scattering grooves 33 for inserting circular bead are arranged beforehand on a blank holder plate 26 and circular bottle-shaped beads 34 are stood on them allowing insertion and removal free. These beads are partially inserted or removed according to the form of drawing of the object product and other cause of generation of folds and adjustment is made for overall balance of partial increase of frictional resistance and slip in resistance at the time of drawing of the blank.
