Robot tool and method for coil packaging

A robot system for coil packaging, comprising:

• two industrial robots, each of the robots being provided with a robot arm having a coupling robot piece configured to interface with a robot tool, said coupling robot pieces being configured to be able to convey actuating power from power supply lines of said industrial robots;
• the robot tool has two opposing ends, each of the opposing ends being provided with a coupling tool piece configured to interface with said robot arm in a direction of an axis extending between said opposing ends to allow for coupling of the robot tool to the robot arm in the direction of the axis extending between said opposing ends and configured to be able to convey actuating power from power supply lines of said industrial robots, a roll holder shaft configured to hold a roll of packaging material, the roll holder shaft at one end being rotatably mounted substantially midway between said opposing ends and projecting substantially perpendicular to the axis extending between said opposing ends, and at least one motor configured to be able to drive, prevent and/or brake rotation of the roll holder shaft by said actuating power.
