Method for guiding a moving web of material










Image Number 2 for United States Patent #4848632.

The invention relates to a method of guiding a web of paper or foil material in a web-guiding device, such web having print marks applied to it at least over stretches of the web, as well as to such a web-guiding device with a correcting device, the latter being adjustable when the center of the web runs off course and with a controlling system connected to an edge-sensing system, whereby the position of the print marks relative to an imaginary guide line is controllable over stretches of the web carrying print marks, and additional correction relating to the latter can be made, if required. According to the invention, print marks signals are produced by means of a print mark sensor and linked with the correction signals of the edge-sensing system, with priority of the print mark signals.
