Fifth, sticky additional page

1. Sticky additional pages. According to the position of the attached page sticking and inserting, the sticky additional page can be used manually or mechanically, but up to now,
This process has not yet been fully mechanized.

Sticky pages by hand. The use of adhesives to connect inserts to signatures is generally done by hand. If the additional page is pasted before or after the signature, it can also be done mechanically. If the additional page is stuck, inserted in the middle of the folding or any position, the folding frame should be opened from the middle, or the folding seam should be cut to stick the insert.

Machine sticky page. Instead of manually sticking a single page to a book, use a sticker sheet machine. The process of sticking a single page machine is shown in Figure 3-4. When sticking a page, the signature that needs to be adhered to a single page is placed on the conveyor chain, and a brush is applied to the edge of the signature crease through the brush wheel 3, and a single page (such as a lining page) is bitten by two-wheeled teeth. It is placed on a folding placard and conveyed by the conveyor chain to the pressure-adhering roller 5 so that the lining page and the folding placard are firmly adhered and then transferred from the conveyor belt to the hopper, and finally the manual receipt is neat and the bonding work is completed.

ZA01 type sticky single page machine can bond single page and double page. The maximum size of the adhesive page is 450×290mm, and the minimum size is 100×70mm. The maximum production capacity is 3000 to 6000 posts/h.

2. Sticky additional pages quality requirements. According to the national industry standard CY/T28-99, the quality requirements for sticky additional pages are as follows.

(1) According to the nature of the paper, the lining and interleaf should be vertical (that is, the fiber direction of the lining page and the interleaf paper is parallel to the back of the book) because the fibers of the cross grain are not easy to be even and easy to produce many wrinkles.

(2) The booklet insert size tolerance ≤ 2mm.

(3)Adhesion to the adhesive should be moderate, and the lining, loose pages and illustrations of the book block adhesive should not be sticky or sticky, and they should be firm and flat.

(4) Sticky mouth requirements are shown in Table 3-1.
