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(ban)送出。蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)裸露到空氣中，為達到水(shui)(shui)分(fen)(fen)(fen)均衡，水(shui)(shui)分(fen)(fen)(fen)大的單面(mian)蜂(feng)窩(wo)(wo)(wo)側放出水(shui)(shui)分(fen)(fen)(fen)，同時(shi)(shi)產(chan)(chan)生(sheng)緊縮；而干(gan)燥的掛面(mian)紙(zhi)(zhi)接收(shou)水(shui)(shui)分(fen)(fen)(fen)而伸長，因(yin)此(ci)產(chan)(chan)生(sheng)上(shang)翹(qiao)曲景象。若當(dang)上(shang)述情況(kuang)相反時(shi)(shi)（實(shi)際上(shang)是與平板(ban)烘缸的干(gan)燥才干(gan)比(bi)較粘合(he)速度(du)過(guo)快(kuai)）則產(chan)(chan)生(sheng)下翹(qiao)。利(li)用(yong)單面(mian)蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)的掛面(mian)紙(zhi)(zhi)比(bi)蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)的面(mian)紙(zhi)(zhi)水(shui)(shui)分(fen)(fen)(fen)多3%的紙(zhi)(zhi)卷(juan)時(shi)(shi)，92%成(cheng)為上(shang)翹(qiao)曲。利(li)用(yong)蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)的面(mian)紙(zhi)(zhi)水(shui)(shui)分(fen)(fen)(fen)比(bi)單蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)的掛面(mian)紙(zhi)(zhi)水(shui)(shui)分(fen)(fen)(fen)多3%的紙(zhi)(zhi)卷(juan)時(shi)(shi)，75%成(cheng)為下翹(qiao)曲。故抉(jue)擇原紙(zhi)(zhi)時(shi)(shi)，掛面(mian)紙(zhi)(zhi)（單面(mian)機(ji)的掛面(mian)紙(zhi)(zhi)與蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)的面(mian)紙(zhi)(zhi)）的水(shui)(shui)分(fen)(fen)(fen)穩定必須堅持3%以內。作為解決上(shang)翹(qiao)曲，除了(le)原紙(zhi)(zhi)水(shui)(shui)分(fen)(fen)(fen)之外在蜂(feng)窩(wo)(wo)(wo)紙(zhi)(zhi)板(ban)機(ji)上(shang)還要(yao)留(liu)神：

1.增加單面蜂窩(wo)機(ji)處的預熱機(ji)與(yu)預處理機(ji)的包角(jiao)。

2.盡量減少(shao)單面(mian)蜂窩機的上(shang)膠(jiao)量。

3.減少過橋上單(dan)面蜂(feng)窩紙板(ban)的(de)沉積量，盡可(ke)能堅(jian)持單(dan)面蜂(feng)窩機與雙面機的(de)速度一(yi)致。

4.盡量減少蜂窩紙板在(zai)裱糊機處的上(shang)膠量。
