Abstract
A system for mounting a hubless glassmaster onto a spindle of an orders measurement device includes a magnet and a hub made of a magnetic material. The hub is designed to fit on the spindle of the measurement device. The magnet is placed on a top surface of the glassmaster and the hub is centered and placed on the bottom surface of the glassmaster opposite the magnet. The magnetic forces between the magnet and the hub hold the hub securely to the glassmaster as it is mounted onto the spindle and rotated in the measurement device. In a preferred embodiment, the hub is first placed in an alignment fixture and the glassmaster and magnet are placed on top of the hub to secure the hub to the glassmaster. The glassmaster assembly is then removed from the alignment fixture for mounting. The system allows both hubbed and hubless glassmasters to be tested on the same orders measurement device without having to affix a hub permanently onto the hubless glassmasters with adhesive.
