  • Vacuum clamping system for assembling cabinets
    Patent number: 5667208
    Abstract: A clamping system is provided for assembling the wall panels of wooden kitchen cabinets and the like, including a frame that is normally supported for sliding movement on an assembly table toward an assembling position relative to a workpiece arranged on the table. The frame is vertically displaceable between a normal elevated transport position and a lowered clamping position relative to the assembly table, and a normally-activated device prevents displacement of the frame from the elevated position to the lowered position. A first suction cup is carried by the frame for connecting to the frame a panel that is to be fastened to the workpiece, and a second suction cup is carried by the frame that is operable, when the displacement preventing device is deactivated, to connect the frame to the assembly table, thereby to clamp the panel to the workpiece.
