Machine for splitting slabs by oxygen-cutting

摘要

For splitting a slab by oxyen-cutting, blow-pipes are mounted on a carriage which is free to move in translation along a girder which is part of a bench driven in translation along rails. The plane of symmetry of the carriage is constantly made to coincide with the plane of symmetry of the slab by means of two sensor runners which bear against the sides of the slab. The runners are carried by two pivotal arms mounted on the carriage and interconnected by a kinematic chain whereby these arms are maintained in a relative position which is symmetrical relative to the plane of symmetry of the carriage.
