CD1100 Full Servo Underpad Production Line

An underpad is a flat absorbent product, not a diaper without tapes

CD1100 forms and cuts underpads. Sheet width and length, core distribution, backing material, folding direction and pack presentation drive the layout. Waist, leg-cuff and side-tape stations used on adult diapers should not be carried into the scope unless the signed product actually requires them.

Material handling that belongs in the trial

The equipment is configured around the customer's finished product and selected inputs. For CD1100, the material trial should help the team confirm sheet dimensions, core distribution, folding and downstream pack presentation while the webs move through wide-web unwinding, heavier core formation, tension control, chassis assembly, cutting and pack transfer.

• Topsheet nonwoven: confirm grade, width, basis weight, winding direction and splice behavior.
• Fluff core (SAP blended): record supplier grade, target dosage or basis weight, and the approved lot.
• PE film: confirm grade, width, basis weight, winding direction and splice behavior.
• Upper & Lower tissue: confirm grade, width, basis weight, winding direction and splice behavior.
• Release paper: check width, release or peel behavior, winding direction and final position.
• hydrophilic topsheet: confirm grade, width, basis weight, winding direction and splice behavior.
• fluff pulp and SAP: record supplier grade, target dosage or basis weight, and the approved lot.

Technical specifications for CD1100

Use the CD1100 figures as a starting point for layout and trials. The proposal should resolve missing fields and explain the conditions behind speed, efficiency and underpad width and absorbent-core control.

Put each quality check close to its defect source

A useful quality plan measures the product after the station most likely to create the defect. It also states who checks it, how often it is sampled and what happens when the result moves out of range. On CD1100, underpad width and absorbent-core control deserves its own trial condition. HAINA and the production team should agree how to confirm sheet dimensions, core distribution, folding and downstream pack presentation, what is measured and what evidence closes the test.

• Name the gauge, camera or inspection method for each critical feature.
• Set sampling frequency and tolerance ownership.
• Record the correction made after an out-of-range result.
• Keep accepted and rejected samples from the same production window.

Control system and line boundaries

A useful CD1100 proposal shows where each adjustment lives and which items remain optional. The four operating areas below also define responsibility for underpad width and absorbent-core control.

Documents and samples that prevent scope gaps

A CD1100 factory test is more useful when its inputs and inspection methods are agreed before the machine is built. The same documents should show how the team will confirm sheet dimensions, core distribution, folding and downstream pack presentation during later recipe changes. HAINA uses this information to keep the CD1100 quotation and the underpad width and absorbent-core control test on the same product basis.

1. Provide one signed taped adult diaper, pull-on pant or underpad sample for every planned size or pack.
2. List material suppliers, grades, roll data, adhesives and permitted substitutes.
3. Mark the critical product checks: core distribution, finished dimensions, tape or seam position, fold symmetry, pack compression.
4. Confirm utilities, floor plan, material loading, waste removal and downstream ownership.
5. Write the production trial around underpad width and absorbent-core control, including duration, sampling and stop records.

Common questions about CD1100

Project fit and next technical step

For CD1100, technical quality comes from traceability: the product defines the process, the process defines the checks, and the test records the result. HAINA should close the project on that basis rather than on a single brochure figure.
