Abstract (en)
[origin: EP0258209A2] In a device for punching sheet metal (43) by means of individually operatable stamping dies arranged in rows, the sheet metal (43) gripped by holding clamps (17) of a cross slide should be able to be punched at any point without rotation. For this purpose at least two holding clamps (17) in the cross slide are adjustable between at least two working positions which are separated by a distance, measured transversely to the rows of dies, equal to at least the width of the punch head (3). <IMAGE>
