The beginning of a web material fed to a processing device and stored in the form of a roll on a core is provided with a machine readable code which represents an identification code for the web material as well as property data relevant for the processing of the web material. The identification code and the property data are read in at the beginning of the processing of the web material and only web materials with valid identification code are admitted for processing. The processing device is adjusted to the web material used by way of the read in property data. At termination of the processing, the identification code and the updated property data of the web material are again recorded in machine readable code onto the beginning of the remaining web material so that they are again available for the next processing procedure. Alternatively, the identification code and the property data can also be stored in a storage element activatable by electromagnetic waves which is mechanically connected with the web material. In this manner, the use of unintended web material types can be stopped. The manual entry of property data can be obviated and a higher user-friendliness achieved. Furthermore, incorrect manipulations are substantially prevented.
A method for processing a web of material stored in the form of a roll in a processing device, comprising the steps of connecting an identification code in machine readable form with the web of material or with a core onto which the web material is wound, reading off the identification code at the beginning of the processing, analysing the code by way of an administration arrangement that cannot be manipulated by the user, and blocking processing of the web material in the processing device by the administration arrangement when the latter was unable to detect a valid identification code.
Apparatus for the processing of a web of material stored in the form of a roll wound onto a core and having a machine readable identification code thereon, comprising a web processing device, a processor based control unit for the latter, a machine reader arrangement for reading the machine readable identification code off the web of material or the core;
