Aligning and stacking arrangement

An arrangement for aligning and stacking laminations and for transporting formed stacks of laminations, the laminations being provided with a circular inner and/or outer circumference and having stamped patterns defining a plurality of stampings distributed about the circumference of the laminations at equal centering angles, the arrangement comprising:

• a stack forming means for receiving laminations fed individually thereto including at least two stack forming elements mounted so as to be selectively separable, said stack forming elements being disposed one above the other in a longitudinal direction of the stack forming means so as to form an upper stack forming element and a lower stack forming element,
• means selectively displaceable into and out of an intermediate stack forming area which surrounds the stack forming means at least in an area of the upper stack forming element for selectively engaging said upper stack forming element so as to maintain said upper stack forming element in a fixed position when said lower stack forming element is displaced to a lowered position and for forming an intermediate stack of laminations including a first ring member rotatably mounted at the intermediate stack forming area, a second ring member fixedly mounted at the intermediate stack forming area, means for selectively rotating said first ring member relative to said second ring member, a plurality of intermediate stack forming members displaceably mounted in said second ring member for a radial displacement, and means arranged at said first and second ring members for causing a displacement of the intermediate stack forming members upon a rotation of said first ring member, and
• means for rotating only said lower stack forming element through stepwise predetermined increments when said lower stack forming element is in the lowered position with the predetermined increments being constituted by a whole number multiple of the central angle of the stampings.
