Cooling apparatus and method for cooling a continuous strip

A cooling apparatus for cooling a continuous strip,

• wherein the cooling apparatus comprises a cooling drum with a cylindrical cooling surface that extends in a circumferential direction and has a rotation axis concentric to the cooling surface and extending in an axial direction,
• wherein the cooling apparatus further comprises a guiding device for guiding the continuous strip in a plurality of windings around the cooling surface,
• wherein the guiding device comprises a plurality of first guiding rollers and a plurality of second guiding rollers,
• wherein each one of the plurality of first guiding rollers respectively forms a set with an associated one of the plurality of second guiding rollers to guide the continuous strip in a transition from a first winding to a consecutive winding of the plurality of windings,
• wherein at least one of the plurality of the first guiding rollers of each set is arranged for receiving the continuous strip from the first winding in a first winding direction and for directing the continuous strip in a first transition direction,
• wherein at least one of the plurality of the second guiding rollers of each set is arranged for receiving the continuous strip in a second transition direction and for directing the continuous strip into the consecutive winding in a second winding direction,
• wherein the at least one of the plurality of second guiding rollers of each set is offset with respect to the at least one of the plurality of first guiding rollers of the respective set in the axial direction and in the circumferential direction,
• wherein the first transition direction is different from the first winding direction and the second transition direction is different from the second winding direction.
