Testing a Paper Roll Slitter Rewinder With Your Own Paper
A buyer's guide to demonstrating a paper roll slitter rewinder using the buyer's own paper stock, with practical checks for slitting width, unwind diameter, and power supply during trials and acceptance.
Before accepting a paper roll slitter rewinder, insist the demonstration run on your own paper stock, not the supplier's sample. Paper grade, moisture, and coating affect how cleanly a 1,100 mm slitting width is held and how well a 1,200 mm unwind diameter feeds without tension problems.
Ask the supplier to run your material at the intended production speed and check slit edge quality, rewound roll tightness, and dust generation. Compare results across your paper grades if you run more than one. Confirm the machine is wired for 380 V, three-phase, 50 Hz and that the trial uses that supply.
For acceptance, agree on measurable criteria in advance: edge straightness, width tolerance at the 1,100 mm reference, and roll uniformity. Request that the trial include a full unwind roll at the 1,200 mm reference diameter so splice and tension behavior can be observed. Ask whether your paper can be supplied for the test and how much is needed.
Before requesting a quote, confirm with the supplier which paper grades the demonstration will cover, whether your own rolls will be used, what acceptance measurements will be recorded, and how the 380 V, three-phase, 50 Hz supply will be verified on site.
