SUPPLY ROLL HAVING FUNCTION MARKING, METHOD FOR HANDLING FLAT AND/OR STRIP MATERIAL WOUND ON SUPPLY ROLLS, AND SYSTEM FOR HANDLING FLAT AND/OR STRIP MATERIAL

摘要

The invention relates to a supply roll (5). The supply roll (5) comprises a roll core (6), flat and/or strip material (8) which is supported by the roll core (6) and wound in a plurality of layers, and at least one function marking (2). The at least one function marking (2) is formed on an external free end region (7) of the flat and/or strip material (8) in a defined relative position such that information about the relative position of the free end region (7) can be optically detected by means of the at least one function marking (2).
