Solutions to common problems of wireless glue binding

Some problems will be caused after the wireless glue installation. Today, I will talk about the solutions to these problems. 1. After the book is glued, the inner pages are simply separated and scattered, the cover is not firmly bonded or the thickness of the glue is uneven. 

A. Whether the selected glue matches the paper. High-speed glue for general paper is sufficient, and high-speed hot-melt glue with stronger adhesion is required for packaging copper paper. B. Check whether the small milling cutter is worn or cracked. C. Whether the clamping table is adjusted too high, it will cause the back glue to squeeze out, so that the back glue is small and the adhesion fastness is not high.

B. Check whether the small milling cutter is worn or cracked.

C. Whether the clamping table is adjusted too high, it will cause the back glue to squeeze out, so that the back glue is small and the adhesion fastness is not good.

D. Whether the set temperature meets the melting point of the glue.

E. Check whether there is too little glue in the back glue box and the side glue box.

2. The book's spine is wrinkled from the glue binding.

A. Check whether the thickness of the front cover matches the thickness of the bound inner page. The width of the bound inner pages is too thick, and the cover used is too thin, which simply causes the spine of the book to wrinkle.

B. Check the unevenness of the clamping surface. Scheduling the way too high will also cause the spine to wrinkle.

     C. There is too little glue, there are bubbles, and the amount of glue in the backing box is too small or the temperature of the glue in the box is low, the glue is not completely melted, and bubbles occur, resulting in uneven glue on the back of the bound book. There will also be wrinkles on the back of the book.

D. Check whether the sun milling cutter and small milling cutter are worn or cracked.

3. The book cover is asymmetrical and skewed from the glue binding.

You can handle it by locating the left and right sides of the scheduling block on the scheduling cover.

4. The spine of the bound book back is square at one end and round at the other end.

Check the back of the bound book. If the back of the book is round at one end, turn the handwheel of the gripping table at the round end of the book in the direction of "square" as indicated on the label.

5. How to bind the hardcover.

Since the hardcover is a thick cover, it cannot be placed on the clamping table, but the inner pages can be glued alone. Do not place the cover on the clamping table, and apply some white oil on the cover table and its clamp ( Sewing machine oil), the inner pages can be clamped and the operation can be done (paste method). After the book binding of the inner core is completed, go to the hardcover.

6. How to bind financial tickets.

Because paper such as financial documents is very thin, it is difficult to align the inner pages. You can use a paper cutter to cut the side that needs to be bound evenly before binding.
