Abstract

A method for the continuous in-register embossing of a stretchable film is provided where a repeating printed image or a laminate may be formed by way of the stretchable film in an embossing station. The embossing station may include a rotating embossing roll having an embossed image and an associated rotating counter-roll. The printed image length of the film may be stretched longitudinally before the embossing contact with the embossing roll to a length greater than or equal to or smaller than or equal to the embossed image length or the circumference of the embossing roll. The maintenance of register of the embossing may be achieved by way of a relative speed between the circumferential speed of the embossing roll and the web speed of the film in the embossing station.
