1. If the single corrugating is on the glue surface, the gap between the pressure roller and the corrugating roller is too small. When the paper is bonded with the inner paper, the inner paper and the corrugated paper will be crushed and broken. If the temperature of the corrugating roller and pressure roller is high, the corrugated paper will be cracked greatly. At the same time, the inner paper will be squeezed and cracked, forming a fracture phenomenon. The common phenomenon is that the inner paper has black lines.

2.楞型設(shè)計(jì)不合理：R和r的配合不能適合厚紙的需求。這類情況容易在E楞和B楞上出現(xiàn)，生產(chǎn)高克重的瓦紙時(shí)，瓦楞不容易成型會(huì)增加瓦楞棍壓力，從而導(dǎo)致瓦紙破裂損傷致里紙現(xiàn)象。

2. The corrugation design is unreasonable: the matching of R and R can not meet the demand of thick paper. This kind of situation is easy to appear in e-corrugation and b-corrugation. When producing high gram weight corrugated paper, the corrugation is not easy to form, which will increase the pressure of the corrugating rod, resulting in the breaking and damage of the corrugated paper.

3.新輥高速里紙破裂：表面光潔度不好，表面粗糙導(dǎo)致壓力不均勻引起破裂。

3. New roll high-speed inner paper cracking: poor surface finish, surface roughness, resulting in uneven pressure, resulting in cracking.

4.接紙時(shí)里紙破裂：接紙機(jī)和制動(dòng)器配合對(duì)瓦紙的張力控制不及時(shí)，當(dāng)原紙水分過(guò)大，張力過(guò)小導(dǎo)致瓦楞成型不良，從而引起破裂。

4. The inner paper is broken when receiving paper: the paper receiving machine and the brake do not control the tension of the corrugated paper in time. When the water content of the base paper is too large and the tension is too small, the corrugating forming is not good, resulting in cracking.

5.無(wú)接紙機(jī)的：瓦楞紙張力相對(duì)過(guò)大。

5. No paper machine: corrugated paper tension is relatively large.

6.瓦楞偏心嚴(yán)重失衡。

6. Corrugated eccentric serious imbalance.

7.小卷芯時(shí)里紙破裂：在制動(dòng)*小的情況下，有可能紙架頂針不平衡機(jī)械抱死，導(dǎo)致原紙張力過(guò)大而破裂。

7. The inner paper is broken when the core is small: when the brake * is small, it is possible that the paper holder thimble is unbalanced and mechanically locked, resulting in the rupture of the base paper due to excessive tension.
