Abstract
A wrapping apparatus, in which the supporting elements supporting a film roll are mounted on the frame of a film dispenser with bearings permitting free rotation so that the film roll supported by them is freely rotatable. The pre-stretching rollers are mutually engaged via a transmission and are likewise mounted on the frame with bearings permitting free rotation. A pendulum roller in the film dispenser and the spring force of a spring applying a load on it have been so adapted that the pendulum roller forms between the second pre-stretching roller and the deflecting roller a bend that functions as a film supply containing a varying amount of film, depending on the prevailing draw of the film to keep the drawing velocity and tension of the film substantially constant at the pre-stretching rollers regardless of the variation in the draw and velocity of the film that is caused by the shape of the article being wrapped.
