ABSTRACT:
An apparatus for use in transporting a sheet stack comprises a wedge-shaped sheet stack holder with a cantilever arm extending from the back of the wedge. A suspending tether is joined to the cantilever arm. A primary tendon extends between the suspending tether and a lever joined to the stack holder. A secondary tendon extends between the suspending tether and the cantilever arm, passing over a clamp on the arm. When the lever is retracted, the stack support is suspended by the suspending tether and the primary tendon. When the lever is extended, the stack is supported by the suspending tether and the secondary tendon, thereby driving the clamp closed. The surface of the stack support arm comprises a dimpled air table.
