Abstract
Abstract Apparatus for transferring material such as hot billets or slabs cut from a continuous casting machine comprises a carriage having pivotable dogs that engage a plurality of lengths of the billets or slabs and move them laterally as the carriage advances. The carriage then retracts and the dogs pivot to inoperative positions. When the carriage is ready to advance again the dogs pivot into operative positions.
