Chose a suitable slitting machine

Firstly, material type:

With adhesive: like double sided tape, foam tape, masking tape, etc.

Without adhesive: like paper, film, label stock, non woven, etc.

Unwind part:

Unwind base: for jumbo roll diameter within 800mm recommend connected unit;?

If jumbo roll diameter is over 800mm, separate unwind base will be recommended.

Unwind shaft

With shaft: regular type, cost-effective

Shaft-less unwinder: two chucks fix jumbo roll; operation is easy, but cost is higher.

Knowledge of Slitting Blades:

1)razor blade: for thin film, such BOPP, etc.

Advantage: lower cost and easy to set up.

2)shear blades: widely used, high accuracy

3)air score blade: mainly for adhesive tapes, non-woven, etc. more difficult to set up.

Edge Trimming Methods

1)Surface trim spool winder: for adhesive tapes

2)servo trim spool winder: for non-adhesive material or low-adhesion material, and not easy tear type

3)centrifugal fan trimming: non-adhesive paper, thin film, etc.

Rewind Unit

Rewind O.D. Specifications:?

450mm, 650mm, 800mm and 1200mm

Rewind Shaft:

Air shaft: suitable for materials with very even thickness.

Differential shaft: separately control tension, when material thickness is not average,?

Web Guide Control System:

Unwind EPC: only unwind base move?

Process EPC: unwind base not move, only the middle part is moving, used more for coating machines
