Abstract

The web stretching method entails feeding a first (Br) and a second (Bl) web strand next to one another and offset parallel to one another by a defined spread dimension. At least one of two deflection devices (5,6) is adjustable from a first position into a second new position in which the first web strand covers a different travel distance than in the first position but maintains its direction of feed so that the spread dimension is adjusted but the wrap angle of the second web strand is not altered through the adjustment of the deflection device. An independent claim is included for a web stretching device by which the aforesaid method is put into practice.
