A device for introducing patterns by radiating a wound continuous substrate. The device provides patterning during continuous roll-to-roll movement without material slippage and with minimal distortion by providing a dancer roll between a processing drum and an unwinder roll on one side, and a winder roll on the other side, for tautly guiding the continuous substrate along a contact surface of at least half of the circumference of the processing drum in order to drive the continuous substrate without slippage. The dancer rolls are adapted to tautly guide the advancing substrate web and returning substrate web with a constant force, and an equilibrium is adjustable between a defined counterforce and the constant action of force on the dancer roll by a stabilization device, and is maintained constant by a controller based on measured deflections of the dancer roll by controlling the rotational speed of the unwinder and winder rolls.
