Abstract

The machine is designed to form turbine blades by a process of rolling combined with forging by reciprocating devices actuated by two similar toothed segments acting in unison. The segments are each pivoted for rotation about horizontal axes. The teeth on each segment mesh with a straight rack in the same horizontal plane. The appts. includes a releasing device to enable the hot formed component to be removed after forging.
