Zusammenfassung:	ABSTRACT In the case of a device to permit the monoaxial length change of film webs in machine direction, which comprises at least one processing gap delimited by two rolls via which a film web is routed in machine direction, whereby the first roll in film transport direction exhibits a first peripheral speed and the second roll in film transport direction exhibits a second peripheral speed, in order to produce film webs with low transverse neck-in as well as reduced edge build-up and to improve the flatness of the film web.
