Patent

CA 2317875

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.

Dans un appareil de fabrication de récipients d'articles de presse à partir d'ébauches de récipient se trouve une pluralité de goupilles de blocage internes d'ébauches disposées de façon à positionner une ébauche de récipient avant le formage à la presse. Les goupilles de blocage peuvent tourner afin d'absorber l'énergie cinétique des ébauches de récipient à mesure qu'elles sont acheminées vers l'appareil et elles éliminent le rebond des ébauches. Dans un autre aspect de l'invention, on prévoit un procédé de formage de plaques utilisant l'appareil amélioré comprenant les goupilles de blocage internes.
