ABSTRACT:
A process and apparatus for the measurement of the dimensions of footwear lasts and for determining reference directions for measurement and manufacture are described. Horizontal and vertical projection tracings are made from a master last, by a mechanical sensing-following mechanism combined with an optical projection system. Deviations from desired positions are rectified by displacing the last, in at least two directions. The location and magnitude of deviations can be marked on the last.
