ABSTRACT:
An arrangement for manufacturing pressed shapes and similar structures in which loading and unloading arms are driven by displacement drive mechanisms. These displacement drive mechanisms have at least two displacement cylinders with strokes that are shorter than either the displacement path of the loading arm or the displacement path of the unloading arm. There is no force transmission from the cylinders to the loading and unloading arms to provide for minimum use of driving power during acceleration intervals when the loading and unloading arms move from a stationary position to a displacement speed.
