First please confirm your material type:
With adhesive: like double sided tape, foam tape, masking tape, etc.
Without adhesive: like paper, film, label stock, non woven, etc.
Here’s a sneak peak of a slitting rewinding machine
Unwind Unit:
Unwind base: for jumbo roll diameter within 800mm recommend connect type;
If jumbo roll diameter is over 1000mm, separate unwind base will be recommended.
Unwind shaft
With shaft: regular type, cost-effective
Shaft-less unwinder: operation is easy, two chucks fix jumbo roll, just cost is higher.
Slitting Slit-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,
it’s a must to install differential shafts
Web Guide Control System:
Unwind EPC: unwind base move
