Method for transferring a metal coil

1. A method for transferring a metal coil on a transfer path between a first coil position and a second coil position, comprising:

supporting the metal coil during the transfer on the transfer path in segments using a plurality of support rollers, and simultaneously unwinding the metal coil

forming an unwinding cradle expanding in a direction of the transfer path by changing positions of one or more support rollers disposed adjacent to each other;

wherein the metal coil is supported by two support rollers disposed on a first frame part in the first coil position and is moved in a direction of the second coil position from said first coil position while said frame part is simultaneously tilted and lowered.

2. The method of claim 1 , comprising pivoting the first frame part on a second frame part, wherein the tilting and lowering movement is generated by a pivoting movement of the first frame part around an axis and a simultaneous pivoting movement of the second frame part around a different axis.

3. The method of claim 1 , wherein the metal coil is supported during the transfer in an alternating sequence by two or by three support rollers.

4. The method of claim 3 , wherein each of the two support rollers disposed on the first frame part are driven by an actuator unit at the same rotational speed.

5. The method of claim 1 , wherein each of a first support roller and a second support roller is disposed on a swivel arm and rotationally driven by a respective actuator unit,

the method comprising setting a rotational speed for each of the first and second support rollers based on a velocity element derived from a pivoting movement of each of the first and second support rollers around a respective axis.

6. The method of claim 1 , wherein the metal coil is supported in the unwinding position by means of an adjustable support roller.

7. A system for transferring a metal coil on a transfer path between a first coil position and a second coil position, comprising:

a plurality of support rollers configured to support the metal coil during the transfer of the metal coil on the transfer path in segments using the plurality of support rollers, during simultaneous unwinding the metal coil,

an unwinding cradle expanding in a direction of the transfer path, the unwinding cradle formed by changing positions of one or more support rollers disposed adjacent to each other,

a first frame part supporting two support rollers for supporting the metal coil in the first coil position, the first frame part configured to be simultaneously tilted and lowered for moving the metal coil from the first coil position toward the second coil position.

8. The system of claim 7 , wherein the first frame part is configured to be pivoted on a second frame part, wherein the first frame part is configured to pivot around a first axis during a simultaneous pivoting of the second frame part around a second axis, the pivoting of the first frame part around the first axis providing the simultaneous tilting and lowering of the first frame part.

9. The system of claim 7 , wherein the metal coil is supported during the transfer in an alternating sequence by two or by three support rollers.

10. The system of claim 9 , comprising respective actuator units configured to drive the two support rollers at the same rotational speed.

11. The system of claim 7 , comprising a swivel arm supporting a first support roller and a second support roller, each of first and second support rollers being rotationally driven by a respective actuator unit, and

a controller configured to set a rotational speed for each of the first and second support rollers based on a velocity element derived from a pivoting movement of each of the first and second support rollers around a respective axis.

12. The system of claim 7 , comprising an adjustable support roller configured to support the metal coil in the unwinding position.
