Abstract
An apparatus and method of forming air turning assemblies is disclosed along with a novel vane supporting rail structure for use therewith. The apparatus holds a pair of rails in spaced parallel relation at a clinching station at which the edges of a vane may be engaged in opposed slotted protuberances in the rails. The spacing of the rails may be increased at the station against a yieldable biasing force, the station including a deforming mechanism for deflecting the vane edges to lock the vanes to the rails. The rails include cam surfaces leading to the vane receiving slots and blocking walls at the trailing ends of the slots to facilitate introducing the vane edges into the slots.
