Embodiment Construction

[0029] Such as figure 1It can be seen that the first embodiment 1 of the device according to the invention for the perforation of the film 2 comprises at least one cutting element 3 and at least one counter-cutting element 5 , through which the contact of the cutting element and the counter-cutting element with the film 2 results in an Make punch holes in. Preferably, the cutting element 3 is arranged on a cutting roller 7 with a direction of rotation 7 a or on another rotatable holding device, and the counter cutting element 5 is arranged on a corresponding cutting roller 9 with a direction of rotation 9 a or on another rotatable holding device device, wherein the axes of rotation 7b and 9b are oriented parallel to each other. In addition if figure 1 As indicated, on the cutting roller 7 , in particular at least two cutting elements 3 are distributed uniformly around the periphery, and on the counter-cutting roller 9 there is a corresponding number of counter-cutting elemen...

Abstract

Disclosed are a device and a method for perforating films. The device comprises a cutting edge and an opposite cutting edge, wherein the opposite cutting edge includes a pattern, which cooperates with the cutting edge along an action line in a manner that a film is perforated in the contact areas of the cutting edge and the opposite cutting edge. In the method using the device for perforating films, the cutting edge is used in cooperation with the pattern of the opposite cutting edge so that a ratio of perforation to non-perforation of the film is defined by the distribution of the pattern along the action line. Thus, a punching slot or the like can be provided on the opposite cutting edge, so that a simple cutting edge which can be replaced inexpensively when worn is used.

Description

technical field [0001] The invention relates to a device for perforating a film and a corresponding method using the device according to the invention. Background technique [0002] Films are known to be suitable for labeling of containers such as bottles. For this purpose, for example, a rolled film web, a film tube or another suitable web-shaped material is uncoiled and provided with transverse perforations at predetermined separation points. The individual labels are then produced, preferably directly before labeling, by separation along the perforations. [0003] A device for transversely perforating web-shaped material is known, for example, from DE 20 2006 015 561 U1. The web-shaped material is guided through between two rotating rollers, wherein on one of the two rollers there are two slotted perforating knives offset by 180°, the two slotted The perforating knife presses the film against the further roller and perforates the web-shaped material there. In this cas...
