Abstract

The screen provides protection for an operator who is required to use his hands in an enclosure where pressing operations etc. take place. The control system allows access to the enclosure during non-bazardous phases of the machine operator but ejects any obstacle rapidly once a potentially dangerous working phase commences. The guard screen is rectangular and in its closed position shuts off the access space at the enclosure (1) front by pivoting (3) along its lower edge, the upper section of the access area being closed off by a transparent flexible screen (5) preventing hands being trapped as the guard rises. The guard (2) is driven pneumatically (6) from a linearly and double acting operating shaft and crank converting the motion from linear to circular, the closure rate and strength being adjustable (9).
