Abstract
A pusher bar assembly (20) having a flexible, horizontally extending pocket bar (22) of sufficient longitudinal extent to push a linear array of glass containers on a cross-conveyer transversely of the cross-conveyor into an annealing lehr. The pocket bar, which engages the containers to be pushed, is disengageably secured to a pair of aligned horizontal pusher bars (26, 28), whose adjacent ends are spaced apart from one another. The pusher bars are secured, respectively, to first and second downwardly extending beams (30, 32).
