ABSTRACT:
A belt-roller crystal pulling mechanism is described. The belt-roller comprises a single driven belt having a vertical run, and a set of pivotally mounted follower rollers for urging the growing crystal in contact with the belt. The pivot mount enables bends or buckles in the crystal to go through the belt and rollers without causing wiggle at the growth interface which might otherwise cause the growing crystal to break free from the meniscus.
