用单面机生产两层瓦楞纸板,经分切后尺寸长短不齐或不正有多种原因:1、模切机的压力辊压力偏小,产生走纸不畅。可就低不就高地加压力解决。2、原纸含水量、高预热量少。胶量多而车速过快,生产的瓦楞纸板含水量高,瓦楞的硬度达不到,而且单面机生产车速远远超过模切机的车速,造成 With single-sided machine to produce two layers of corrugated cardboard, after cutting the size of the missing or not the size of a variety of reasons: 1, die-cutting machine pressure roller pressure is too small, resulting in poor paper. Can be low on the high pressure to solve. 2, paper moisture content, high preheat less. Plastic volume and speed too fast, the production of corrugated cardboard moisture content, the hardness of corrugated reach, and single-sided machine production speed far exceeds the speed of die-cutting machine, resulting in
