联合国国际贸易中心包装高级顾问约翰·塞林先生最近在参观了上海纸箱厂和纸盒一厂等有关单位后,认为我们先轧出瓦楞芯纸,然后上胶,再用手工进行裱糊这种生产工艺落后,容易造成瓦楞的变形和倾斜,影响了纸箱的强度。他建议,应在现有的设备基础上加以革新,设法采用牛皮卡纸和芯纸同时成卷进给的加工方法,在芯纸成型的同时就裱糊到牛皮纸上,以固定住瓦楞的形状。这样既可提高纸箱强度,减少纸箱的用纸克重,也可方便操作,减轻劳动强度,值得我们研究。现选译 Kopper 公司生产的400型无托纸器单瓦楞机,以供参考。
John Selin, senior consultant for packaging of UNITC, recently visited the Shanghai Carton Factory and the first carton factory and other related units, that we first out of corrugated medium, and then glue, and then hand-made paper production Technology behind, easily lead to corrugated deformation and tilt, affecting the strength of the carton. He suggested that it should be based on the existing equipment to be innovative, try to use kraft paper and core paper at the same time into the feed processing method, in the core paper molding at the same time the paper to kraft paper, to fix the corrugated shape. This will not only improve the strength of the carton, reduce the weight of the carton paper, but also easy to operate, reduce labor intensity, it is worth our study. Kopper is now the choice of translation and production of 400-type single paperless single corrugator, for reference.
