Abstract
Cases (covers) for binding books are made in a series of sizes which differ from each other in the width of the spine and each size accommodates a range of book cores. The gauge of the present invention indicates which size case is proper and further measures the precise thickness of the core. Simultaneously, the gauge moves an edge guide of a positioning guide so that the core is located accurately centered relative to the spine area of the case and the case is also located relative to the guide.
