Abstract
In an apparatus for manufacturing pressware containers from container blanks there is provided a plurality of inertial blank stop pins disposed so as to position a container blank prior to press forming. The stop pins are rotatable in order to absorb the kinetic energy of the container blanks as they are fed to the apparatus and eliminate blank bounce. In a further aspect of the invention there is provided a method of forming plates utilizing the improved apparatus including the inertial blank stop pins.
