In electric motors working with alternating current (AA/AC)[1], the parts of the rotor and stator that conduct magnetic flux are made of layered sheets to avoid fuco currents. In order to make rotor and stator sheet packages, 0.35 - 1.5 mm thick, single or double-sided insulated sheet metal sheets are cut into strips on scissor benches.[2] The sheet metal strips formed in this way can be used immediately without the need for any further processing in the construction of strip core transformers and machines.[2] The hair strips coming out of the scissors are given to the die-cutting press, which works in series. 500000 kp presses with 300 - 500 cuts per minute remove the stator and rotor sheet profiles in a series of cuts one after the other.

Since the rotor and stator sheet profiles[2] are cut in such a way that they fill the gaps of each other (with mold), the amount of scrap pieces at the end of production is very low. Large diameter rotor and stator sheet packs are usually removed in one cut. For this, the previously prepared disc-shaped hair is placed on top of each other. Sheets of sheet placed in this way are cut in a single move in the die-cutting press. The necessary grooves for the placement of the windings are made on the machines. If the amount of parts to be processed is not large, the grooves are opened one by one in the automatic slotting machine. For large quantities of parts and large diameter sheets, automatons that can open 5-6 grooves at a time are used. The hair from the slotting machines is weighed on special counter scales, layered on top of the stacker and combined into a hair pack under a pressure of 5-10 kp/cm².
