Before the confrontation of the book, the pages of the book should be paged in order, stacked and folded afterwards, and flattened with a flattener. The glue was used to glue the machine and the adhesive ratio was Henkel A8065-1. Glue: White glue: Water 2nd: 3:3.
The positioning of the device should be used when confrontation, such as the inner page of three posts a total of 6 pages, followed by the first post: empty 1 + closed 20 text 1 + empty 2; second post: empty 1 + text 2+ text 3 + Empty 2; Third post: Empty 1+ Text 4+ Three+ Empty 2. Firstly, the third placard is empty 1 upwards, and it is placed on the positioning backing: give the second placard empty 2 glue, and on the empty 1 of the third placard, mark the edge of the line and the bottom of the bottom rule to locate the backing. The two right-angled edges are aligned; the empty 2 of the first frame is glued, and the empty line 1 on the second frame is aligned with the two right-angled edges of the positioning frame. At this point, the inner page is completed. More times can repeat the above order. We will stack the inner pages of the back and forth and stack them every five times, press and pressurize the flattening machine, and then place the flattened inner pages neatly in a uniform order, and apply glue on both ends of the spine, with a width of about 20mm. After the split wait for the cover.
The cover also needs to be glued, but there are no glues in the three marks at the spine, and it can't be glued to the spine of the inside pages of the book. Its main function is to open the book when the book is opened and to seal the four spine. Can open an irregular trapezoidal hole, the role of this hole can make the book full open four pages, the size of the hole should be determined by the thickness of the book, too large or too small will affect the reading effect. Every step in the production process must be carefully handled, and some negligence may affect quality. In order to effectively prevent the glue from sticking at the spine of the cover and the spine of the inner page during sizing, before the gluing, a sponge can be attached to the lower part of the gluing machine's paper feeding table, which can effectively prevent the glue from being uploaded. The non-adhesive part should be slightly wider than the width of the three traces. At the same time, positioning rules should be placed on the feed table to ensure that the cover jam can be perpendicular to the drum axis during the gluing process.
After the back surface has been coated with glue, lay it flat on a countertop, align the inner core of the copy with the mark on the front side and the bottom edge, and use the right hand to press the mark to fold it up so that the cover wraps around the inner core. When folding the lines of the Laos, the force should be even, so that the entire line of the line is turned upright, and the trace angles are smoothed to make the edges and corners clear. The semi-finished book formed by the cross-cutting is flattened and fed to the flattener every five times. After it is fully dried. Cut the finished product and round the corners. The rounded corners and the adjacent edges smoothly transition without obvious cuts and burrs. Cards with special-shaped requirements must be die-cut.
