Wet Wipe Nonwoven Cross-Cutting
A wet-wipe web reaches the cutoff as a lubricated, compressible fold or stack rather than a dry single layer. Added lotion changes friction and fiber mobility, while folded plies can shift or spring apart, so the knife must be reviewed with the actual saturation and fold geometry.
Updated
Where This Cutting Application Appears
Cross-cutting folded wet-wipe logs
Separate a continuous folded web into individual or grouped wipes after lotion application.
Cutting stacked travel-size wipes
Portion multiple thin plies where alignment must be preserved through compression and release.
Trimming saturated nonwoven tails
Remove irregular starts or ends during setup and splice recovery without dragging the folded web.
Folded-Web Cross Cutting process boundary
folded-web cross cutting for wet wipe nonwoven webs is planned around separation across the material flow or part axis to establish a controlled repeat length or finished end; it is not longitudinal width conversion, shaped contour production or particle-size reduction.
Folded-Web Cross Cutting setup checkpoint
For wet wipe nonwoven webs, confirm target length, datum or registration reference, feed indexing, support on both sides, cut timing and post-cut transfer.
Folded-Web Cross Cutting acceptance checkpoint
For wet wipe nonwoven webs, evaluate length distribution, squareness or cutoff angle, both cut faces, deformation, registration drift and stacking or discharge consistency.
Define the Required Cut Result
- Complete separation through every wet ply
- Consistent wipe length despite fold movement
- Low fiber pullout and no long connecting tails
- Clean discharge without product sticking to the working surface
Problems to Diagnose Before Changing the Knife
The folded web moves with the knife
Check lotion level, hold-down timing, surface friction, cutting angle and support on both sides.
Lower plies remain connected
Review compressed stack thickness, penetration, backing condition, stroke parallelism and local fold overlap.
Fibers form long tails at exit
Inspect edge wear, nonwoven direction, blade lift, cutting speed and whether saturated fibers are stretching.
Cut wipes adhere or bunch at discharge
Compare lotion chemistry, blade finish, release motion, guides and accumulation after the cutting point.
Knife Forms That May Be Considered
| Possible knife form | When it may be considered | What must be confirmed |
|---|---|---|
| rotary cutoff knife | A synchronized rotary edge may suit continuous folded web when phase, compression and counter-surface are controlled. | Confirm rotor interface, cutting width, timing, rotation, anvil or lower edge and maximum saturated fold build. |
| serrated straight knife | Progressive tooth engagement may suit a thick folded log, but tooth pull can increase lint or strand tails. | Confirm pitch, depth, direction, stroke and accepted wet samples before choosing a serrated profile. |
Information to Send for Technical Review
You do not need to know the exact blade name. Send the available workpiece, machine, current-knife and cut-result information so the application can be reviewed against a drawing or sample.
- Nonwoven fiber and bonding construction
- Dry basis weight, thickness and machine direction
- Lotion chemistry category and saturation range at cutting
- Fold pattern, ply count and compressed stack thickness
- Target wipe length and inspection tolerance
- Line speed, cutoff timing, hold-down and discharge layout
- Current knife, counter-surface and cleaning schedule
- Fresh rejected samples showing tails, shifted folds or sticking
Questions About This Cutting Application
Why must saturated samples be tested instead of dry nonwoven?
Lotion changes friction, compression and fiber movement. Dry tests can miss dragging and release problems seen on the line.
What causes only the bottom fold to remain attached?
Backing wear, insufficient penetration or uneven stack build may affect the lowest plies. Check defects across the cutting width.
Can deeper penetration solve connected fibers?
It may damage the backing or accelerate wear. First verify edge continuity, stack compression and stroke alignment.
Why do cut wipes bunch after release?
The compressed fold can recover while lotion promotes sticking. Review discharge guides and timing as well as the knife.
How should wet-wipe rejects be supplied?
Seal representative samples to preserve saturation, identify feed and fold direction, and include accepted pieces for comparison.
