Seed Tape Roll Slitting Blades
Use roll slitting when a wider carrier web is divided into parallel seed-tape lanes. Confirm whether seeds and adhesive are applied before or after slitting; the knife path must be evaluated against the actual seed pattern.

Where This Cutting Application Appears
Supplied workpiece and state
Confirm the actual carrier: paper, tissue, cellulose-based laminate or another customer-approved construction; record layer count, fibre direction, adhesive pattern, seed species, seed spacing, seed profile, carrier thickness, moisture and roll orientation. USDA describes seed tape as seed embedded in a paper-based planting aid, but that does not define every commercial construction or a MEIRENTE tool.
Installed process checkpoint
Map cutter positions to the web edge, centreline and seed rows; record fibre direction, web tension, tracking, cutter pitch, adhesive state and rewind layout.
Output and inspection stage
Measure lane width and seed-to-edge clearance across the roll; inspect fibres, delamination, adhesive transfer, seed contact and roll-edge build.
Roll Slitting process boundary
Confirm that the actual customer operation matches this process name, supplied product form and approved drawing before evaluating a replacement tool.
Roll Slitting setup checkpoint
Record product direction or pattern, conditioning, retained piece, installed interface and downstream handling before a controlled trial.
Roll Slitting acceptance checkpoint
Use customer-approved dimensions and visible-defect limits on labelled samples from the same supplied state and line settings.
Define the Required Cut Result
- Measure lane width from the approved web datum
- Measure seed-to-edge clearance at registered sample positions
- Inspect both edges for fibre pull, delamination and adhesive transfer
- Record seed contact and rewind defects separately from slit quality
Problems to Diagnose Before Changing the Knife
Lane width drifts relative to seed rows
Compare web tracking, registration, cutter pitch, runout and the selected datum.
Paper fibres or laminate layers pull at the edge
Review fibre direction, moisture, support, overlap or clearance and edge entry.
Adhesive builds up or a seed contacts the knife path
Map the adhesive and seed pattern before changing the tool or cleaning interval.

Acceptance Criteria for a Controlled Trial
Agree how the trial will be judged before changing the knife or machine setting.
- Measure lane width from the approved web datum
- Measure seed-to-edge clearance at registered sample positions
- Inspect both edges for fibre pull, delamination and adhesive transfer
- Record seed contact and rewind defects separately from slit quality
Knife Forms That May Be Considered
| Possible knife form | When it may be considered | What must be confirmed |
|---|---|---|
| Existing shear or score-slitting set | For a line already designed around the documented web-support method. | Confirm shaft, holder, overlap or penetration, runout and rewind tension. |
| Existing razor or straight-edge slitting holder | Only when the carrier construction and machine safely support that method. | Confirm support, entry angle, exposure, seed exclusion and guarding. |
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.
- Carrier material, layer count, fibre direction, coating and adhesive pattern
- Seed species, profile, spacing, orientation and acceptable seed-contact exclusion zone
- Tape thickness, width, moisture, roll build and supported or unsupported condition
- Target geometry, datum, tolerances and accepted fibre, adhesive or seed-damage limits
- Existing machine, holder, shaft, counter-surface and interface drawings
- Web speed, tension, tracking, registration, trim handling and rewinding method
- Current tool plus labelled accepted and rejected samples from the actual roll
- Trial quantity, cleaning constraints, packing format and annual demand

Questions About This Cutting Application
Can a knife form be selected from the workpiece name alone?
No. Confirm the supplied state, actual cutting motion, installed interface, current tool and accepted and rejected samples.
Should seeds be present during the slitting trial?
Use the actual production stage; applied seed and adhesive may change the risk and result.
Can seed spacing be inferred from tape width?
No. The customer must supply the pattern and exclusion zones.
