Achieving a customized converting solution with a minimum of effort

The drive's axis control block provides the basic functionality for motion control tasks: Enabling or disabling the axis, error handling, synchronous operation and much more.

Axial winders in machines used for processing continuous material webs consist of a drive axiswhich unwinds or rewinds the material to be processed. The speed and torque can be adapted to the diameter to achieve maximum tension precision and constancy. The Converting Toolbox can be used to realize axial winders for different applications and a wide variety of materials.

Accumulators enable a roll change while the machine is still in operation. When a wound roll is to be changed, it is braked down and the machine process is supplied by emptying or filling the accumulator. After the change, the accumulator returns to its initial state.

Whether stiff (direct) or flexible (through the material) – coupled axes are used in numerous applications. Load sharing between the drives is required if rigid or flexible coupling is used.

Automatic roll change ensures top levels of productivity, as there is no need for interruptions caused by braking and acceleration processes for the roll change. The expiring web is spliced to the new web while the machine is still running. The old web is then cut off from the expiring roll and the rest roll is moved to the changing position, where it can be easily replaced.

Tension control is used to keep the material tension constant and to control the tension when required to prevent the material web being damaged or even torn. Various open or closed control techniques for various measuring systems are implemented in the function.

Traversing drives are coupled to winder drives. They ensure that the material to be wound is positioned with utmost precision on a core, for example, to achieve a defined edge structure of the coil. Traversing drives are mainly used for winding flat material.

Rotary knives are used to cut or perforate continuous material webs. They are attached to one or more rotating rollers. During cutting, the cylinder's circumferential speed is adapted to the material (synchronous range), format adjustment is carried out outside of the cutting range (format range).

Flying saws are used to cut endless material webs into sections. The saw – mounted on a driven slide - moves at the same speed as the material, which is returned to its starting position after the cutting process has been terminated.

Disturbance compensation improves tension precision, especially with low speeds and small loads. It counteracts system-related periodic disturbances, thereby reducing speed ripple.
