Patent ID: 8573013

Claim:
A flexer station ( 50 ) for the pre-treatment of metal sheets ( 1 , 2 ) to be rounded in a rounding apparatus ( 4 ), wherein in the flexer station a target impact position (x) of a metal sheet on a measurement plate ( 38 ) is ascertainable as a reference for the adjustment of at least an adjustable element ( 20 , 9 , 7 ) of the flexer station, and wherein the impact position (y, y′) of the metal sheet on the measurement plate is determined by means of a sensor arrangement ( 45 , 38 ) during the motor-driven passage of the metal sheet through the flexer station, by means of which a signal showing the impact position is provided, by means of which the impact position or a value derived therefrom is representable on a display device ( 25 ) and/or by means of which an element of the flexer station determining the pre-treatment of a metal sheet through the latter is adjustable by means of a controller ( 5 ) and an actuator in such a way that a deviation from the target impact position in the direction of the passage of the metal sheet is diminished for the subsequent metal sheet.
