Method for winding a winding material, computer program product, controller and winding machine

A non-transitory computer program product encoded with a computer program which, when executed by a controller of a program-controlled apparatus, causes winding of a winding material from a supply device onto a winding body, having a non-circular cross section, of a winding machine, the computer program comprising:

• program code for providing the winding material from the supply device;
• and
• program code for winding the winding material provided from the supply device onto the winding body via at least one deflection roller;
• wherein an actual winding tension of the winding material is set to a setpoint winding tension depending on a position-dependent compensation signal, stored in a storage unit, for compensating a changeable free length, resulting from the non-circular cross section of the winding material, of the winding material between the at least one deflection roller and the winding body;
• and
• wherein the position-dependent compensation signal is calculated depending on a respective determined position of the winding body for a simulated winding cycle consisting of a number of rotations of the winding body and is stored in a table of the storage unit.

A controller for a winding machine, comprising:

• a regulation unit which is configured, utilizing at least one of (i) drives and (ii) a setting unit, the controller being configured to:
• operate such that provide a winding material provided from a supply device;
• and
• operate such that the winding material provided from the supply device is wound onto the winding body via at least one deflection roller;
• wherein an actual winding tension of the winding material is set to a setpoint winding tension depending on a position-dependent compensation signal, stored in a storage unit, for compensating a changeable free length, resulting from a non-circular cross section of the winding material, of the winding material between the at least one deflection roller and the winding body;
• and
• wherein the position-dependent compensation signal is calculated depending on a respective determined position of the winding body for a simulated winding cycle consisting of a number of rotations of the winding body and is stored in a table of the storage unit.

A winding machine for winding a winding material, comprising:

• a supply device for providing the winding material;
• a winding body having a non-circular cross section;
• and
• a controller having a regulation unit which is configured, during winding of the winding material provided from the supply device onto the winding body via at least one deflection roller, to set an actual winding tension of the winding material to a setpoint winding tension depending on a position-dependent compensation signal, stored in a storage unit, for compensating a changeable free length, resulting from the non-circular cross section of the winding material, of the winding material between the deflection roller and the winding body, and being further configured to calculate the position-dependent compensation signal depending on a respective determined position of the winding body for a simulated winding cycle consisting of a number of rotations of the winding body and is stored in a table of the storage unit.
