Description

Used by the head to locate the edge of the plate. Located on the drum, above the LECs, at the encoder end.

The strip is held is place with two cap screws and two button heads with bellville washers to give a four point hold.

On early VLF Platesetter engines, the strip is glued on the drum using epoxy. Consult VLF Engineering before replacing these strips.
