ABSTRACT:
An apparatus for assembling air turning vane and rail structures of the type having a plurality of turning vanes consisting of longitudinally spaced apart curved airfoil plates disposed between a pair of parallel upper and lower plate-like rails, and used to promote laminar air flow in heating, ventilating and air conditioning ducts, compresses an array of vanes between a pair of rails to interlock upper and lower transverse edges of the vanes with the upper and lower rails. The apparatus includes a work table for holding the lower rail of a vane and rail structure to be assembled, and lower and upper laterally disposed comb-like vane guides disposed above the work table provided with laterally spaced apart, vertically aligned pairs of slots, each adapted to receive a vane in an upstanding position above an intended fastening location in the lower rail. A ram plate driven downwardly by a linear actuator presses downwardly on an upper rail placed in position above the upper transverse ends of the vanes, causing the upper transverse ends of the vanes to lockingly engage with the upper rail, and to couple downward translational motion of the ram plate and upper rail into downward motion of the lower transverse edge walls of the vanes, causing the latter to lockingly engage the lower rail.
