ABSTRACT:
A pusher mechanism for attachment to the carriage, saw guard, or other appropriate point of a rotary-blade stone slab saw. Using either signals from a controller of a modern slab saw or self-generated sensor information, the pusher is actuated at a precise time in the cutting process and applied an outward pressure on the severed slab to ensure that the slab is directed away from the saw blade. While a pneumatic cylinder is typically used, either hydraulic, electro-mechanical, or mechanical mechanisms may also be used to accomplish the push-away function.
