Abstract

Procedures with its performing device, to extend and stretch plastic films of the removed sleeve, made by the blowing process in order to distribute thickness tolerances in the peripheral direction of the sleeve, taking place the blowing and the winding or the subsequent treatment of the film in stationary devices and the extension plane of the film band being tilted back and forth around the axis of the sleeve in a reversible manner in each case after at least approximately 360ºC, characterized in that the sleeve band, once extended, it is deflected around a deflection axis that is reversible together with the plane of expansion run with respect to it and arranged in a plane perpendicular to the extensor rotary axis, and is then driven around other deflection axes arranged in planes parallel to the plane containing the first axis of deviation, and which are likewise tilted in a re Versible around the extensor rotary axis, decreasing the tilting angles of the deflection axes with increasing distance from the place of extension, and the successive deflection axes running alternately at least those closest to and further from the extensor rotary axis, and because, finally, after being driven around the last of the deviation axes, it is evacuated in a constant direction in another plane perpendicular to the extensor rotary axis.
