Abstract
An arrangement for aligning and stacking laminations for electrical equipment and for transporting formed stacks of laminations with the laminations being fed individually in the same position to a stack former which maintains the relative positions of the laminations. The laminations include a circular inner or outer circumference and a plurality of stampings distributed about the surface of the laminations at equal centering angles. The stack former is provided with an appropriate circular circumference and a guide which can be introduced into at least one stamping. The stack former is rotatably mounted relative to its longitudinal axis and is provided with a rotary drive which operates in a stepwise manner with the rotary steps of the drive being equal to the central angle of the stampings of the stamping pattern or a whole number multiple thereof.
