Abstract: A transfer for elongated articles such as angles, flats, channels or rounds includes an optionally deployable rolling restraint to maintain rounds such as bars or tubes properly on the transfer during operation thereof. More particularly, the transfer is in the form of a relatively thin stacking carriage which elevates to pick up a single layer of predetermined width of such articles to transfer the same to the top of a stack being formed. The relatively thin stacking carriage pivots downwardly adjacent the top of the stack and then retracts with adjustable uprights on the stacking cradle causing the layer to be wiped off onto the top of the stack. During such retraction, the top surface of the stacking carriage must be free of obstructions to permit the layer properly to be wiped therefrom. Accordingly, a rolling restraint is provided for the stacking carriage which will move from an ambush position to a position projecting slightly above the top surface of the carriage as it elevates to lift the layer.
