Embodiment Construction

[0021] figure 1 A machine 10 for the tobacco processing industry is shown in which a web 11 of printable or printed material, such as a paper web, is endlessly processed. The machine 10 includes a sensor device 14 with an optical camera 15 which is arranged in the machine 10 to capture images of the printed side of the material web 11 . The camera 15 is preferably a line scan camera, but may also be an area scan camera. Such as figure 2 As shown, the line scan camera 15 preferably extends over the entire width of the material web 11 . It is also possible for the camera 15 to extend over only a part of the width of the material web 11 . The printed side of the strip of material 11 is at figure 1 In the example of , it points upwards, that is to say towards the sensor device 14 . In addition, the machine 10 also includes a machine control mechanism 16 and a cutting mechanism 17 for cutting the strip of material 11 along a periodically repeating cutting line 34, see figur...

Abstract

The invention relates to a machine for the tobacco processing industry and a method for obtaining the position of a strip of pre-printed material in the machine. In a method for detecting the position of a pre-printed material web (11) in a machine (10; 21) of the tobacco processing industry, the endlessly processed material web (11) is detected and identified by means of an imaging sensor device (14) The method is characterized in that a freely definable pattern is used as the printed pattern to be recognized, which pattern is arranged on the material In the region of the strip (11) that is visible from the outside on the finished product.

Description

technical field [0001] The invention relates to a method for detecting the position of a pre-printed material web in a machine of the tobacco processing industry, wherein the periodically repeated printed pattern on the endlessly processed material web is acquired and recognized by means of an imaging sensor device and thereby Determine the position of the material web relative to the machine cycle time. Furthermore, the invention also relates to a correspondingly configured machine for the tobacco processing industry. Background technique [0002] In the prior art, in order to detect the position of the pre-printed material web in a machine of the tobacco processing industry, contrasting printed markings predetermined by the manufacturer are printed on the material web. These printed markings are generally arranged in such a way that they overlap the finished stick-shaped product by material overlapping, so that they do not interfere with the visual impression of the produ...
