Rubber bookbinding machine processing lock money book

The edition of the album and the atlas. The design of the pass-through version is many. Simply using the glue-stitching processing method, the back-to-page version after milling, and the loss of the pass-through screen, are relatively difficult to read. And simply use the sewing line to set the processing method. Connected version, pass version of the screen are no loss, flipping effect is not bad, but after the sticky card and manual package. It takes time and effort to ensure the appearance of the appearance. Consistent. Therefore, we thought that the use of glue to pack the machine to lock the thread after the processing of the book on the cover, and the actual effect is also very good, now the specific approach and should pay attention to the links described below.
1. After laying the lock line on the back of the book, it should be noted that the thread must be tightened when the sewing thread is processed. Otherwise, the inner pages of the book can easily be pulled out.
2. The glue booked on the machine's milling back. The slotted table descends so that it does not touch the back of the book.
3. The glue pot temperature of the machine is set slightly lower than the normal use temperature (about 20°C or so) for the purpose of making the hot melt adhesive thicker to increase the thickness of the glue layer. The characteristic of hot melt adhesive is that the glue liquid is thin when the temperature is high. The glue layer is thin, and the glue liquid is thick when the temperature is low. Thick glue layer.
4. The offset paper with a basis weight of 70 g/m′ is cut into long strips of length equal to the size of the hair book and slightly wider than the thickness of the book. It is also possible to print paper.
5. The book is sized on a rubber book, but it is not spliced ​​directly on the rubber wheel after milling and backing, and the pre-cut offset paper is manually spliced ​​into the location of the book and attached to the back of the book. This processing requires the back of the book to be flat, with a thick and even layer of glue, and a gap between the signatures. Fill in, otherwise black holes will appear in the final cut.
6. Remove the dry-molded book from the unbonded part of the offset paper and prepare the upper cover.
7. The temperature of the glue pan is adjusted to be slightly higher than the normal use temperature of the glue book, which is about 10C higher than that of the normal glue book, so that the glue liquid is thin and the glue layer is thinner, and the trimmed cover is set aside for use.
8. According to the normal bookbinding package operation procedure, the rubber book was once covered by the rubber wheel and covered on the cover.
9. Three sides after cutting the packaging factory.

At this point, the binding of the stapled binding book is completed with the processing of the cover on the machine. However, one thing to note is that if it is the first time after the white paper jammed on the loop cover, the first time the glue is not changed, the white cardboard must be indented. The second time the glue should be slightly thicker. The general principle is that the thicker the cover material, the thicker the glue layer should be. In addition, the empty book (empty glue) that was removed after the first glue application must be repaired before the upper cover. The specific method is to raise the temperature of the hot plate of the flat-ironing machine, and push the appropriate amount of empty glue book Pressure hole: Observe the melting of the hot melt adhesive from the edge surface of the back of the book, and remove the glue immediately after it is opened, and then dry it. If the back of the book is skewed, it can be corrected with the handbook on the ironing board.
The picture book processed by this method. The map book, the appearance is correct, from the sky. Check the book back. The glue layer and the signatures are smooth outside and the inside is serrated and very beautiful. After opening, the page is flat. Complete and effective.
