Abstract

A two-pocket folding machine has a case formed by a top case portion hinged to a bottom case portion. The case has a top pocket and a bottom pocket, with each pocket including a first plate and a second plate. The top case portion includes the first plate of the top pocket, with the top pocket first plate being fixed to the top case portion. The bottom case portion includes the first plate of the bottom pocket, which is fixed to the bottom case portion. A moving assembly includes preferably a pair of movable panels, with the second plate of the bottom pocket and the second plate of the top pocket being fixed to the movable panels and moving with the moving assembly. The moving assembly is displaced along a predetermined trajectory with respect to the top and bottom case portions during opening and closing of the top and bottom case portions such that the second plates are parallel to and close to the corresponding first plates when the case portions are closed. The first and second plates move away from each other in both the top and bottom case portions when the case portions are open to provide ready access to the insides of the pockets.
