Abstract
The paper reviews the progress made in the clamping of plywood, especially in the last 35 years, when wooden hand screws and wooden-frame hand-screw presses were in general use. Improved hand clamps, improved hand-screw presses, and power-screw presses have their uses for certain classes of work and comparatively small output, and inverted-cylinder hydraulic presses are necessary for special methods and classes of work. Plywood is an artistic and utilitarian product with increasing appeal for both manufacturing and construction purposes. As the market for plywood products expands, new problems will necessitate further advances in press design. Plywood presses of the future may outdistance those of the present as much as the presses of the present demonstrate improvement over the old hand presses.
