Application and Industry usage

Doctoring Rewinding Machine is a technique heavily used by (CONVERTERS INDUSTRY). The converter industry normally refers to companies who print, coat and laminate materials. A typical converter is a company that produces (FLEXIBLE PACKAGING) material for packaging food. This may involve purchasing large rolls of plastic film such as (BIAXIALLY ORIENTATED POLYPROPYLENE) (BOPP) which is then printed to the customer's design and coated with cold seal adhesive for use on high speed packaging machines. This material is printed and coated in wide, large diameter rolls for maximum efficiency. The rolls are then slit, using a slitting machine, into smaller rolls of the size to be used on the packaging machine.

For metal coils, the slitter consists of three main parts: an un coiler, slitter, and recoiler. The material is fed from the un coiler, through the nip between the two circular cutting wheels (one on top and another underneath), and then re-wound in slit pieces on the re coiler.

When the term "slitter and Re winder" or "Doctoring Rewinding Machine" is used to describe the machine, the three parts are referred to as the unwind, the slitting section and the rewind. Slitter and Re winders are normally used to slit plastic films, paper and metal foils. The unwind stage holds the roll stably and allows it to spin; it is either braked or driven to maintain accurate tension in the material. Some machines have a driven unwind which reduces the effect of inertia when starting to unwind heavy rolls or when the material is very tension-sensitive.

The slitting section has three main options:

• Razor slitting, which is ideal for thin plastic films - the system is very simple and quick to set. Although the razor blades are low cost, they need to be frequently changed to ensure a good quality slit edge.

• Rotary shear slitting. Male and female circular knives engage to give a scissor cutting effect. This system is used widely on paper, films and foils. Although the knives take longer to position, they stay sharp longer than razor blades. The setting time can be reduced by using an automatic knife-positioning system.

• Crush cut slitting. A male knife runs against an anvil. The system works well with certain materials including non-woven and foams.
The rewind section also has options. The main type is centre winding using differential rewind shafts. These shafts are becoming universal on most slitting machines. The differential shafts ensure an even tension across the full width of the material. Closed-loop control of the winding tension using feedback from load cells provides the total tension-control system required for running tension-sensitive materials. Precise and accurate tension control is the key to good roll slitting. Modern machines use AC vector drives with closed-loop feedback from AC motors. When used with the correct control algorithms, they produce excellent results with the minimum of maintenance.
