Condition - 1 { Paper wrinkles tension warp
If you're facing issues with paper wrinkling, tension, and warp, it's essential to determine the underlying causes to address them effectively. Such issues could be due to worn brake shoes, which can lead to excessive web tension and cause paper wrinkling and warping. Alternatively, slipping brakes may also cause similar issues. To resolve these problems, it's crucial to make the necessary brake adjustments or repairs, ensuring proper tension and avoiding paper wrinkling.

Moreover, elephant-skin paper with significant caliper variations can also contribute to paper tension issues. This paper type often has uneven thickness throughout its surface, causing tension problems during production. In such cases, trimming off the outer layer of bad paper can help eliminate the issue and improve the overall quality of the output.

Carriage misalignment is yet another possible cause of paper tension and warp, where the roll stand arms are not parallel or correctly aligned to the splicer, resulting in uneven tension distribution. To address this issue, parallel the roll stand arms for proper level and alignment to the splicer.

Finally, preheater and preheater's wrap/fixed idler rolls can also contribute to paper tension problems. Ensuring that the preheater and its wrap/fixed idler rolls are correctly aligned can help avoid tension issues during production.

In conclusion, identifying the root causes of paper wrinkling, tension, and warp is crucial in addressing these issues effectively. Don't hesitate to take the necessary actions, such as brake adjustments or repairs, trimming, and alignment, to improve the quality of your output.
