Claim:
1. An apparatus ( 1 ) for winding-up a metal strip ( 2 ) into a coil ( 3 ), comprising a clamping pair ( 22 ) formed of a deflection roller ( 23 ) and a pressure roller ( 24 ) and located in front of the coil ( 3 ) in a material flow direction ( 10 ) so that the strip ( 2 ) is retained under tensional stress with respect to the coil ( 3 ) and is so bendable that the strip ( 2 ), which is provided with a corresponding pre-bend, is firmly wound into a coil ( 3 ), characterized in that a first bending roller ( 35 ) that is pressable against the deflection roller ( 23 ), is arranged in front of the clamping pair ( 22 ) in the material flow direction ( 10 ) and a further bending roller ( 36 ) that is adjustable relative to the deflection roller ( 23 ), is arranged behind the clamping pair ( 22 ) in the material flow direction ( 10 ), wherein the pressure roller ( 24 ) and first and further bending rollers ( 35 , 36 ) are so displaceable relative to the deflection roller ( 23 ) that an end region ( 45 ) of the strip ( 2 ) is additionally curved to form the pre-bend dependent on an end diameter ( 48 ) of the coil ( 3 ).
