YD Shaftless Positioning Sheeters: Reporting Cutting Quality Issues

When sheet quality changes, a clear record of the job is more useful than guessing a machine setting. Yueda's YD1300 and YD1400 positioning sheeters are described for packaging paper and board with shaftless roll handling. Shaftless refers to the roll-handling arrangement; it does not mean every part of the machine is free of mechanical shafts.

This guide explains what to record for a quality review or supplier support request. It is not a troubleshooting sequence, operating instruction or substitute for the manual supplied with the machine.

Describe the result before assigning a cause

State what changed: sheet length, edge condition, squareness, print positioning where applicable, surface marks or stacking condition. Note whether the issue is continuous or intermittent, when it first appeared, and how it differs from the accepted sample. A visible defect alone does not identify a faulty sensor, knife, drive or tension setting.

Keep representative accepted and rejected sheets labeled with job and batch references. Record dimensions using the agreed inspection method, units and sampling points so different people can compare the same evidence.

Prepare the material and job history

• Machine model and serial reference, job number, date and shift.

• Paper grade, grammage, supplier and batch number.

• Roll width, diameter and core information from the material records.

• Required sheet size and the applicable acceptance criteria.

• Whether the issue began after a roll change, format change or other documented event.

• Displayed alarm text and existing approved production or maintenance records.

Include print-mark requirements only if they apply to the confirmed machine configuration and job. Do not assume every positioning task uses the same registration method. The product specifications and the sheeter acceptance checklist can help structure the quality discussion.

Keep evidence collection within safe procedures

Collect photographs and observations only from safe, authorized positions. If a condition may be unsafe, follow the site's stop, isolation and escalation procedures. Do not reach into moving equipment, bypass guards or make knife, drive, sensor or tension adjustments to test a theory.

Inspection, adjustments and maintenance must be carried out by authorized personnel following the exact model manual and site procedures. This article does not prescribe a pressure, speed, calibration method or repair action.

Close the review with an agreed quality check

After an authorized response, the responsible production and quality staff should agree how the output will be checked against the accepted sample and job requirements. Record the outcome and any remaining questions for the next shift. Repeated issues should retain the same batch and job references so the history is not lost.

Send the machine reference, material information, defect description, relevant samples and safe photographs through Yueda's contact page for support review.
