Abstract
The disclosed supply roll (5) comprises a roll core (6); flat material and/or strip material (8) being carried on the roll core (6) in a multitude of windings; and at least one functional marker (2). The at least one functional marker (2) is placed in a specified relative position at an externally arranged free end section (7) of the flat material and/or strip material (8) such that information about the relative position of the free end section (7) is optically identifiable by way of the at least one functional marker (2).

A method for handling flat material and/or strip material (8) wound onto a supply roll (5), comprising:
- applying at least one adhesive marker (3) in a position onto an externally arranged free end section (7) of the flat material and/or strip material (8) on a supply roll (5), wherein the at least one adhesive marker (3) comprises a transparent window (24) through which an end edge (18) of the externally arranged free end section (7) is visible;
- positioning the supply roll (5) on a retaining mandrel (15);
- optically identifying the position of the at least one functional marker (2);
- aligning the free end section (7) based on the optical identification step;
- and
- extracting the free end section (7) from the supply roll (5).
The method of 9, with wherein the at least one adhesive marker (3) is attached to the free end section (7) and to a layer (11) of the flat material and/or strip material (8) adjacent to the free end section (7), such that the at least one adhesive marker (3) fastens the free end section (7) to the adjacent layer (11).
An apparatus (100) for handling flat material and/or strip material (8) wound onto supply rolls (5), the apparatus comprising:
- a device (50) to apply at least one functional marker (2) in a position onto an externally arranged free end section (7) of the flat material and/or strip material (8) on a supply roll (5), wherein the at least one functional market (2) comprises a transparent window (24) through which an end edge (18) of the externally arranged free end section (7) is visible;
- at least one installation position (EB) for the rotating reception of supply rolls (5) of flat material and/or film material (8);
- a handling device (10) for mounting the particular supply roll (5) into the at least one installation position (EB);
- an optical detection device (30) for identifying a position of the at least one functional marker (2);
- and
- one or more devices for aligning the free end section (7) of a particular supply roll (5) based on the optical detection such that the free end section (7) of a particular supply roll (5) in the installation position (EB) has a predefined position.
