This is a guarding solution developed by people from Waldun Group, Teal Jones Group and Streifel Industries.
When a block is loaded on the carriage a guarding flap is opened by the use of an overhead air valve. This allows the spalt to pass through and be discarded. The valve is then closed and the flap moves back into guarding position and the shingles are processed.
The trim saw guard is the other part of the West Coast Solution. A molded clear guard and improved table prevent contact with the trim saw.
The following videos show the West Coast Solution in operation:
Below are some high resolution pictures of the guarding solution as configured on the test system.
