ABSTRACT:
A pair of shifting supports for supporting a shiftable shear housing in a flying shear machine for cutting traveling stock comprises a parallel crank mechanism which, together with a crank mechanism of a pair of shearing drives, is incorporated in a motive power transmission mechanism provided on a base and driven, together with a pair of shifting drives, by a common driving power source, the cranks of the parallel crank mechanism rotating one or two revolutions per revolution of a main shaft for shifting drive of the pair of shifting drives, a movement approximating a straight-line motion along the travel direction of the stock being imparted to the shiftable shear housing in at least a shearing interval of the forward stroke of the reciprocating movement thereof caused by the pair of shifting drives.
