4. A cutting and welding method for welding a tail of a first metal coil strip to a head of a second metal coil strip, comprising:
providing a cutting head on a first carriage movable on a guide extending transversely across the first and second coil strips;
providing a welding head on a second carriage movable independently of the first carriage on the guide transversely across the first and second coil strips;
clamping the tail of the first coil strip and the head of the second coil strip in respective clamping jaws;
parking the first and second carriages side-by-side on the guide in a first parking position adjacent and completely beyond first lateral edges of the first and second coil strips;
cutting the tail of the first coil strip and the head of the second coil strip and subsequently welding the tail of the first coil strip to the head of the second coil strip by sequentially moving the first and second carriages completely across the first and second coil strips and parking the first and second carriages side-by-side on the guide in a second parking position adjacent and completely beyond second lateral edges of the first and second coil strips;
providing the cutting head as two spaced apart cutting heads on the first carriage disposed in fixed positions at predetermined distance from one another in a longitudinal direction of the first and second coils strips and simultaneously cutting the tail of the first coil strip and the head of the second coil strip with respective ones of the two cutting heads.
