Abstract

An active code carrier is located inside a spare paper roll that includes a tube or core. The code carrier interacts with either a reading head, or a writing head. This enables roll-specific data to be read or updated at any time. This is particularly useful for automated roll transport and roll handling systems.

Claims

1. A spare web roll comprising:

a winding tube, said winding tube having a hollow tube interior and a tube body defined by an inner tube body surface and an outer tube body surface;

a material web wound on said winding tube and in contact with said outer tube body surface; and

a code carrier having a data memory, said code carrier being associated with said spare web roll outside of said hollow tube interior in said material web adjacent said outer tube body surface, said code carrier being activated with data outside of said hollow tube interior.

2. The spare web roll of claim 1 wherein said code carrier can be inductively coded and read.

3. A spare web roll comprising:

a winding tube, said winding tube having a hollow tube interior and a tube body defined by an inner tube body surface and an outer tube body surface;

a material web wound on said winding tube and in contact with said outer tube body surface; and

a code carrier having a date memory, said code carrier being associated with said spare web roll outside of said hollow tube interior, said code carrier being activated with data outside of said hollow tube interior after partial consumption of said material web wound on said winding tube.
