then.Usually, the folding trace line of compacting is to adopt special impression device to carry out in the process of making this compound package material.At first adopt impression device on paper, to suppress required folding trace line, drench multiple plastics surface layer then on the surface of paper, again through making required packaging material at last with series of processes such as aluminium foil are compound.Existing impression device comprises protruding roller of impression and the recessed roller of impression, and the outer surface of protruding roller of impression and the recessed roller of impression all is the face of cylinder.The impression bar that has some projectioies on the outer surface of the protruding roller of impression, the impression groove that has some depressions on the outer surface of the recessed roller of impression, the impression bar is corresponding one by one with the impression groove.Protruding roller of impression and the recessed roller of impression are installed on the frame by bearing, and their axis is parallel to each other, direction of rotation.Have certain interval between protruding roller of impression and the recessed roller of impression, paper can be passed through from this gap.Protruding roller of impression and the recessed roller of impression are in rotation process, and the impression bar on the protruding roller of impression progresses in the impression groove of the correspondence on the recessed roller of impression, leaves the impression groove more gradually, moves in circles successively.After paper passes through between protruding roller and the recessed roller of impression from impression, by corresponding impression bar and the required folding trace line of impression groove extrusion.Fig. 4 is the impression bar 3 on the protruding roller 1 of existing impression and the cross sectional representation (enlarged drawing) of the impression groove 4 on the recessed roller 2 of impression.As shown in Figure 4, the cross section of impression bar 3 is rectangle substantially, and the cross section of impression groove 4 is rectangle substantially.The cross section of impression bar 3 has top margin 5 and 6, two sides 6 of two sides are parallel to each other, and all vertical with top margin 5.In the process of processing top margin 5 and side 6, at first form the wedge angle of one 90 degree in the top margin 5 and the intersection of side 6, then this wedge angle has only been carried out chamfering one time, through only having formed a hypotenuse 11 after the chamfering, this hypotenuse 11 intersects with top margin 5 and side 6 respectively.Fig. 5 adopts the cross sectional representation (enlarged drawing) of above-mentioned impression device to the folding trace line 17 of paper 12 compactings, and Fig. 6 is the D portion enlarged drawing among Fig. 5.Because the thickness very little (generally in 0.24～0.41mm scope) of paper 12, in the process
