Printing and molding of Jinan handbag

　　（1)先将模切机的底板清洗干净，粘上双面胶，再铺上一层定量约爲500g/m2的厚纸板，使它坚固地粘在底板上(2)采用较大的模压压力，开动模切机对厚纸板中止压痕，厚纸板经过多次重压后会呈现较深的沟痕，要留意不能将纸板压裂。

　　(1) clean the bottom plate of the die-cutting machine, stick on the double-sided adhesive tape, and then lay a layer of thick cardboard with a ration of about 500g / m2, so that it can firmly stick on the bottom plate. (2) start the die-cutting machine to stop the indentation of the thick cardboard, and the thick cardboard will show deep groove after multiple times of heavy pressing. Pay attention not to fracture the cardboard.

　　(3)调小模压压力，放入纸张，压出折叠痕迹。这种折痕既要有一定的深度，使手工折叠时不易跑线，但也不能太深，使纸张被压破或折叠后分裂，或许由于折痕处塑性变形过重，招致手提纸袋在当前的运用中容易分裂，影响运用寿命。特别是在对牛皮纸中止压痕加工时，由于牛皮纸较脆，韧性不如铜版纸，更要恰外地控制模压压力。

　　(3) reduce the molding pressure, put in the paper and press out the folding trace. This kind of crease should have a certain depth, so that it is not easy to run the line when folding by hand, but it should not be too deep, so that the paper is crushed or split after folding. Perhaps due to the excessive plastic deformation at the crease, the portable paper bag is easy to split in the current use, affecting the service life. Especially in the process of stopping the indentation of kraft paper, because the kraft paper is brittle, toughness is not as good as that of copper plate paper, it is necessary to control the molding pressure exactly.

　　爲了使手提纸袋既好折，又不于压裂，需求留意以下几点。(1)垫纸要具有足够的厚度;(2)模压前先将垫纸压出沟痕;(3)正式模压时的压力要恰当;(4)沿着纸张的丝缕方向，纸张比较好折，模压压力可小些;而垂直于纸张丝缕方向，纸张比较难折，可在局部添加模压压力。

　　In order to make the portable paper bag easy to fold and avoid fracturing, the following points should be noted. (1) the pad paper shall be of sufficient thickness; (2) the pad paper shall be pressed out of the groove mark before molding; (3) the pressure during the formal molding shall be appropriate; (4) along the wire thread direction of the paper, the paper is easy to fold, and the molding pressure can be smaller; while perpendicular to the wire thread direction of the paper, the paper is difficult to fold, and the molding pressure can be added locally.
