METHOD AND ARRANGEMENT FOR SYNCHRONIZED POSITIONING OF AT LEAST ONE ESSENTIALLY CONTINUOUS MATERIAL WEB

A method for synchronized positioning of a web for manufacturing products. The method includes feeding the web into a production apparatus at a first speed; processing in the production apparatus, with the web being fed forward at a second speed; and detection of each synchronization mark for positi...

Beschreibung
Zusammenfassung:	A method for synchronized positioning of a web for manufacturing products. The method includes feeding the web into a production apparatus at a first speed; processing in the production apparatus, with the web being fed forward at a second speed; and detection of each synchronization mark for positioning the respective motif in a predetermined position on each product. The method includes the following steps: generation of a reading of the actual value of a virtual master function upon the detection, which includes a cyclic clock where the number of cycles per product includes an integer; comparison between the actual value and the expected value of the virtual master function; and stretching of the web in response to any deviation between the actual value and the expected value, with the aim of minimizing the deviation.
