Twisting Device and Method for a Hairpin Winding

A device (1) for twisting hairpin ends of a coil formed from hairpins for an electric machine, the device comprising:

• a plurality of coaxially arranged twisting rings (2.1;
• 2.2;
• 3) comprising:
• two outer twisting rings (2.1;
• 2.2) and, therebetween,
• at least at least two inner twisting rings (3),
• wherein the twisting rings (2.1;
• 2.2;
• 3) have, in each instance, at an axial end facing hairpin ends, a plurality of pockets (6;
• 6.1;
• 6.2) distributed over a circumference for receiving a hairpin end, respectively, and
• wherein the twisting rings (2.1;
• 2.2;
• 3) are twistable in opposite directions relative to one another, wherein the twisting rings (2.1;
• 2.2;
• 3) have couplings (4.1;
• 4.2) by which twisting rings (2.1;
• 2.2;
• 3) with like rotational direction are connectable.
