單面蜂窩紙板在單面蜂窩機及裱糊機處均要上膠，橫向伸長大，而掛面紙（面紙張）因為直接與預熱器跟雙面機的平板烘缸接觸形成過干燥狀況，進入雙面機的冷卻部后成為蜂窩紙板送出。蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)裸露(lu)到空氣(qi)中，為達到水分均(jun)衡，水分大的(de)(de)(de)單(dan)面(mian)(mian)蜂(feng)(feng)(feng)窩(wo)(wo)(wo)側放出水分，同時產生(sheng)緊(jin)縮；而干(gan)燥的(de)(de)(de)掛(gua)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)接(jie)收水分而伸長，因此產生(sheng)上翹(qiao)(qiao)曲景象。若當上述情況相反時（實際上是(shi)與平(ping)板(ban)(ban)(ban)(ban)烘缸的(de)(de)(de)干(gan)燥才干(gan)比較粘合速度(du)過快(kuai)）則產生(sheng)下翹(qiao)(qiao)。利用單(dan)面(mian)(mian)蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)掛(gua)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)比蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)水分多3%的(de)(de)(de)紙(zhi)(zhi)(zhi)(zhi)卷時，92%成為上翹(qiao)(qiao)曲。利用蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)水分比單(dan)蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)掛(gua)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)水分多3%的(de)(de)(de)紙(zhi)(zhi)(zhi)(zhi)卷時，75%成為下翹(qiao)(qiao)曲。故抉擇原紙(zhi)(zhi)(zhi)(zhi)時，掛(gua)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)（單(dan)面(mian)(mian)機的(de)(de)(de)掛(gua)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)與蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)）的(de)(de)(de)水分穩定必須堅持(chi)3%以內。作為解(jie)決上翹(qiao)(qiao)曲，除(chu)了原紙(zhi)(zhi)(zhi)(zhi)水分之外在蜂(feng)(feng)(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)機上還要留神(shen)：

1.增(zeng)加單面蜂窩機處的預熱機與(yu)預處理(li)機的包角。

2.盡量(liang)減少單面蜂窩(wo)機的上膠量(liang)。

3.減(jian)少過橋上(shang)單面(mian)蜂(feng)窩(wo)紙(zhi)板(ban)的沉積量，盡可能堅持單面(mian)蜂(feng)窩(wo)機與雙面(mian)機的速度一致。

4.盡(jin)量減少蜂窩紙(zhi)板在裱糊(hu)機處的(de)上膠量。
