Abstract
A novel device for clamping together a sandwich-type gel slab plate assembly includes an elongate housing having a recess on one side and two movable bars placed parallel to each other inside the recess. Due to a series of angled parallel surface segments on the lateral edges of the bars and one side wall of the recess, a vertical force against one bar translates into a lateral force against the other, urging the latter toward the other side wall of the recess, clamping the plates in between with even force along the entire length.
