Luxury hardcover new technology

1. The working process of the combination of luxury hardcover assembly process and processing luxury hardcover is: cutting sealing paper, coating seam adhesive, sleeve, pressure groove (on the copper plate) stereotypes, paint liner adhesive, adhesive liner Root material, seal adhesive, adhesive lining, flattening, natural drying, finished product inspection, packaging.
1) Cutting lined paper in luxury hardcover installation method. The ring lining and the signature are locked together, and do not adhere to the lining of the book case, so it is necessary to cut and seal the envelope paper. There are two types of specifications for envelope paper. The length of the large specification is the length of the book block, and the width is the width of the cardboard minus a width of the flap. The length of the small size is the length of the cardboard minus the width of the two edges and two cardboard thicknesses. The width of the board is reduced by two edging widths (or one) plus a cardboard thickness. The cutting specifications of the sealed paper are extremely strict and the tolerance is only 0.5mm.
2) Before applying the adhesive, the adhesive must be applied on the middle seam and the viscosity should be slightly higher. Do not apply the adhesive to the edge of the cardboard when applying it. After coating, it can be used for shelling. When it is sleeved, it should be subject to the specifications of floating ports, and must not be skewed. The well-packed book is to be pressed along the groove with a tool (press plate, etc.) so that the middle seam of the book shell and the spine part are firmly adhered, and piled up on the book board one by one until the press slot is shaped.
3) The bookcase after press-slot setting should be immediately pressed on the copper board. The role of pressure groove shaping; First, the book shell seam and spine part firmly bonded, play the role of the book shell and book block connection; Second, after the pressure groove to increase the appearance of books and grades. Pressure tank can not be hot-pressed (can not be used for heating the slot machine), hot-pressing easy to book cover hot and hot-pressing time is not easy to set, so use cold pressure method (ie, with copper plate). The time for pressing the trough is not less than 3 hours (the longer the better). When the groove is pressed, the book slot must be placed in a copper line and must not be placed or not grooved.
4) Coat the root adhesive to stick the lining material book After the pressure groove, apply the adhesive on the opposite side of the lining material and seal it with the cover of the book cover and seal it with the three seals. The adhesive used when sticking the lining material must be selected according to the texture of the material to ensure a firm bond. After the lining material sticks, it must be flattened, so that it can be bonded firmly and smoothly without wrinkles.
5) Coated Adhesives Encapsulating paper The book that adheres to the lining material and is flattened and dried is firmly sealed on the seals 2 and 3 of the book. Sealing paper has two layers and one layer. The small size of the sealing paper is used to fill the recesses and increase the pulling force of the sealing paper for the large thickness of the book cover; the large-size sealing paper is a ring lining. Role. The sealing paper should be sticky and sticky, and it must be pressed for the last time after sticking so that it can be flat and wrinkle free. The flattened books must be stacked neatly and allowed to dry naturally for 12 hours before inspection and packaging. This completes the entire process of the luxury hardcover assembly process.
One of the luxury hardcovers is the processing of inlaid gems, such as the inlays of special medals, the inlays of luxury bookcases, etc., which will not be described here.
2. In addition to the same book block and general hardcover, there is also a book block that is made into a shape of a butterfly book and is equipped with a lock and processed into a luxury hardcover butterfly book block process and processing luxury hardcover. This processing method is generally used for military maps, high-end maps, high-end celebrity paintings and so on. The butterfly book block is characterized by its strong and durable connection. The feature of opening a book page is that it does not see the stitches and holes, and the figures and pictures are not damaged by the eye holes. This kind of processing technology is used most in map processing units, because if there is a hole in the entire picture, it is very likely that a position is damaged and the integrity of the original cannot be maintained. The butterfly device can solve this problem well.
The luxurious hardcover butterfly book block process flow is: open material, folding, sticking, connecting butterfly book stickers, folding posts, flattening, affixing, sewing thread seaming, viscoelastic lining, flattening, tying, coating Adhesives, dry ingredients, cut books, three sticky.
1) The material for opening and closing has book stickers and various pieces of materials. The size of the posters should be in accordance with the size specified in the construction plan. The specifications of other pieces are as follows.
a) Fabric strips. The materials used are silk, poplin, and plain cotton. The specifications are the same length as the book block and 30-40 mm wide.
b) Paper long strips. The weight and thickness of the offset offset paper used should be slightly less than the size of the text on the book. The specifications are the same as the length of the fabric, 20-30 mm wide.
c) Fill the strips. The material used is the same texture as the book sticker and the weight is low. The specification: the length is the same as the length of the book block, and the width is 10mm.
2) Sticking strips Apply the adhesive to the middle of the strip after applying the adhesive. Claim:
a) The adhesive is selected correctly, smeared thin and uniform;
The order is stuck in the middle of the splicing, and the two sides are uniform, sticky, sticky, and flattened without sticking.
b) Folding and pasting Folding and pasting refers to the use of adhesives on the sticky joints of the cut pages, where the printed pages are folded in half, and the letters are folded on the outside to form a one-fold, two-fold page. Into a paste, and press the level of operation. Claim:
c) The book is folded and folded correctly, with a tolerance of ±0.5 mm, and it is flat and firm without wrinkles.
d) The adhesive is selected correctly, the sticking mouth width is the same as the face of the piece, the sticking agent is even and uniform, and no spilling or blooming:
e) After the book is glued, it should not be skewed with the seams of the ordering material, and the tolerance should be ±0.5mm.
3) After folded into a butterfly book, the single page will be folded and glued to the splicing, and the centerline of the sewed sliver shall be used as the basis for folding it into a butterfly book and pressing the same. The folding requirement of Butterfly Stickers is extremely strict, and the tolerance is only 0.5mm, because the sticky edge of the butterfly book core is exposed after the cutting. If not, the whole book will directly affect the appearance of the book, so the skill requirement of the operator is higher.
When the butterfly book is posted, it can be used for page matching, thread locking, flattening, book cutting, and three-viscous book block processing. After the shelling and splicing, an exquisite luxury hardcover butterfly book will be displayed on you. In front of you.
