1, What is wireless adhesive bookbing?
Adhesive bookbinging refers to a bookbinging method in which each page of the printed product is fixed on the spine of the book with glue. Different from the previous wired bookbinging, wireless bookbinging does not use wire, no wire, but glue the book block. The core of the wirelessly bound book can be used for both paperback and hardcover, and is the main bookbinging method for books with a larger print number.
Here is an interesting story, wireless bookbinging in foreign countries have a name is: perfec bookbinging, that is, perfect bookbinging. It can be seen how outstanding the advantages of this bookbinging method are in the production process.
2. Operation mode of wireless adhesive installation
The operation mode of wireless adhesive installation is different from that of riding nails, and the inner page and cover need to be pre-treated respectively, and finally combined by bonding.
The process flow is roughly: page, into the book, milling back, wool, upper side glue, book back glue, bag cover, molding, glue cooling, double, slitting, cutting finished products, stacking finished products, testing finished products, bundling.
3, The advantages of wireless bookbinging
(1) Because the wireless bookbinging process is simple and more adhesive equipment is used, it is fast and time-efficient.
(2) The bid can be opened at 160 degrees, and if PUR glue is used, it may be close to 180 degrees.
(3) The maximum thickness of the glue can reach about 7 cm, and there is a great degree of freedom for matching pages.
4, Wireless packaging precautions
(1) After soaking and drying the glue in the hot melt glue, it is impossible to open the book to the end, and it is impossible to read the 3mm part of the bookbinging area. Therefore, the center position of the inner page should be deviated from the stitching 2 ~ 3mm.
(2) Hot sol packed books should not use more than 157 grams of paper, because the paper is too thick, it may cause the spine of the adhesive degumming break.
(3) The thickness of the tender bookbinging is usually between 3 mm and 30 mm. If the book block is too thin, it cannot be used on this machine. If the book block is too thick, it will easily cause the glue to disstick and break when reading. In general, the thinner the paper, the greater the thickness allowed for wireless adhesive.
(4) The book with the cover hole, because the cover incision must be handled first, and then the hot sol is easy to be squeezed and deformed after clamping, so it is not suitable to use wireless bookbinging, but it can be considered to use the lock wire bookbinging method.
