Abstract

Fixed plate of the press carries a die and stops in the lower part for holding the blank on the die. The moving plate carries punches, an ejector and an element for centering the blank on the die. The fixed plate also has to movable bridles in the plane of the die, facing one another on an axis perpendicular to the direction of movement of the blank for keeping it on the face of the die. Specif., each bridle may consist of a sprung wedge carrying an S-shaped piece having its lower end turned in towards the die and its upper end turned out.
