Abstract
A method and an apparatus are directed to stretching plastic films. The plastic film is held at at least two opposite longitudinal sides by a plurality of holding means and the holding means are guided along stretching paths at both longitudinal sides of the plastic film. In order to increase productivity, several plastic films are held, mutually spaced one on top of the other, by the holding means and are simultaneously stretched. The holding means, in terms of their number and/or design, are constructed and arranged such that several plastic films can be simultaneously stretched mutually spaced one on top of the other.
