Abstract: An automatic stacking machine for stacking curved articles and placing them on a pallet. Individual articles are guided to a position between two vertical locating plates on top of a catch plate. Once positioned, the catch plate is removed so that the article drops onto one or more horizontal arms. A stack is formed on the horizontal arms in this manner, and the arms can be lowered to place the stack on transport plates. The transport plates hold a stack between two additional vertical plates, one of which rotates to a horizontal position to allow the plate to be pushed, while supported by the other plate, onto a waiting pallet. The pallet is mounted on a pallet frame which can be coupled to other pallet frames and is raised on a rising and lowering platform to be adjacent the stacking machine for loading.
