Coiling device for a large range of metal strip thicknesses

A coiling device, comprising:

• a coiler having a coiling mandrel for coiling a metal strip which is fed in a feed direction (x) to the coiler,
• a coiling swing arm having a rear pressure roller and a deflection plate,
• a swing arm drive configured to line up the coiling swing arm with the coiling mandrel and to
• drive the coiling swing arm away from the coiling mandrel, and
• an upper duct flap arranged upstream of the coiler as seen in the feed direction (x) and configured for the purpose of guiding the metal strip to the coiler,
• the coiling swing arm also has a front pressure roller in addition to the rear pressure roller, and the coiling device comprises a flap drive operable for positioning the upper duct flap such that, when the coiling swing arm is lined up with the coiling mandrel, the upper duct flap being movable from a first position between the coiling mandrel and the front pressure roller of the coiling swing arm to permit the metal strip to be deflected around the coiling mandrel only by the rear pressure roller and by the deflection plate of the coiling swing arm to a second position upstream of the front pressure roller of the coiling swing arm as seen in the feed direction (x) to permit the metal strip to be deflected around the coiling mandrel by the front pressure roller, the rear pressure roller and the deflection plate of the coiling swing arm.
