Rotary arm rewinding machine


This method is more suitable for coiling a more fragile polymer coated film, film-foil structure (as opposed to coiling polymer coated paper and paperboard). In order to be able to transfer and maintain tension from another fully loaded core in the axial direction without disturbing the tension, each mandrel of the swivel rewinder is driven by a DC motor. The boom rewinder is capable of adapting to inline slitting, which is already common after the application of new electronic controls.
In the case of a rewinding machine that produces a non-cutting reel and slits and rewinds before use, the in-line slitting allows the reel coming out of the swivel rewinding machine to be applied. The boom rewinder has a variety of different reel delivery systems available from different machine manufacturers. The rewinding process should:
(1) Provide the ability to have online slitting if needed.
(2) Minimize and eliminate the waste transportation of the core and outer layers of the finished reel regardless of the diameter and line speed.
(3) Reproducible reel transport regardless of line speed. Rewinders with shaftless boom winding characteristics are available from some machine manufacturers. Its advantage here is that it does not require a steel shaft or an aluminum shaft, only the core of the paper that is clamped onto the mandrel. As the extrusion process continues to advance in speeding up the production line, additional important issues have arisen. The problem is material handling. Fortunately, there are many companies that specialize in material handling to provide these systems. They should:
1. Remove the full roll of coated material from the swivel rewinder.
2. Pull the shaft out of the reel (if there is an axis).
3. Reload the new core onto the shaft.
4. Apply an adhesive to the core.
5. Reinstall the winding position of the shaft-input rewinder with the core.
6. Arrange the rolled roll and take it to the next destination.
This is done automatically, without the assistance of a machine operator. These systems are needed because it is impossible for humans to keep up with changes in high line speeds.
