ABSTRACT:
A device for separating shadow masks from a strip of base material includes a conveyor upon which the strip moves. Two loading plates are arranged above the conveyor and press the strip against the conveyor. The loading plates are separated by a space which is angularly disposed with respect to the axis of the conveyor. A tensioned wire is arranged in the space and a magnet raises a fully etched portion of the shadow mask over the tensioned wire as the shadow mask enters the space. The tensioned wire thus shears the partially etched shadow mask from the strip of base material.
