Case Making Gauges are hand or machine-fed machine used to assemble the covering material, boards and inlays of case-bound edition books. It is constructed of stainless steel and aluminum so that it can be easily washed and cleaned. All parts that contact the work are made of Teflon or Teflon treated aluminum. The entire mechanism can be removed for washing by loosening the two thumbscrews at the pivot points and rotating the clips over the pivots. The unit can be lifted off the pivots and taken away for cleaning. The gauges are suitable for library binding as well as edition binding work. Thumbscrews adjust the friction between the carriages and the guide rails and prevent the inlay guide blades from moving freely when the gauge is lowered.
