Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spine binding method for Western-bound books, and more specifically, to a spine binding method that does not use binding thread.

When binding together the contents of a Western-bound book after alignment and collation, thread binding or wire binding is used to bind the contents after alignment and collation, and thread binding or wire binding is used to bind the contents using thread or wire. Perfect binding in which only adhesive is applied is commonly used.

In the former case, with flat binding, the distance between the binding position and the spine is the same as with Japanese-bound books, and as with saddle stitching, it is not suitable for welfare when the content is thick. The problem of breaking in and tightening is added, and the workability is poor. In addition, in the case of unscrupulous people, the cut-in type is not suitable for thick contents, and the to-shize perfect binding type creates scratches partially and applies adhesive. There were some disagreements such as being excluded.

The purpose of this paper is to eliminate the above-mentioned drawbacks of the conventional paper, and its features are that the stacked paper sheets are pressed against one side or both sides, and the back surface of the stack is pressed. He fluffed the fluff, applied cooking liquor to the back part, and then performed an operation to entangle the fluff before the cooking liquor applied to the part dried, and then fluffed the back part ( This invention provides a spine binding method that does not use binding thread, in which the cooking liquid is dried and solidified by applying ultrasonic vibrations.

An example of this generation illustrated in the drawings will be described below.

In the spine binding method of this invention, as shown in FIGS. 1(a) and 1(b), first printed paper (including blank paper) 1
Cut the sheets to the required size without folding them, stack them together in a certain number, and align at least two sides. Next, as shown in Figure 2 (a) and (b), Although the configuration is not shown, for example, a pressure lip 2 of a manual or power pressurizer using a screw, lever, or fluid pressure applies pressure from one or both sides perpendicular to the paper surface of the printing paper 1 to apply pressure between the printing papers. After the Ichinoseki surface was exposed by lifting, the edge 4 of each printing paper forming the back part 3 was fixed to the shaft 5, and countless triangular stones were excavated with a triangular punch on the circumferential surface. Eye 6
The fluffing is performed using the fail roller 7 which has been formed with a fluff pattern.

Further, as shown in FIGS. 5(a) and 5(b), a roller is disposed in a cooking liquid storage gutter 8 to which a liquid cooking liquid (described later) is constantly supplied to the fluffed back surface. After uniformly applying IIkw6 liquid with brush 9, the fluff is thoroughly entangled with the fluff before the cooking liquor dries using metal brush lO, which moves from side to side and to the front edge.

After doing this, the pair of diaphragms 12a and 12b to which ultrasonic vibration is applied is moved to the (ultrasonic) vibration generator 11.
If necessary, the back vibrating plate 12c is used to apply vibration (ultrasonic waves) to the vicinity of the back part as shown in FIG. It sinks and solidifies, forming a binding layer 13 on the back portion 3 as shown in FIG. 5, and perfect binding is completed.

Further, as the above-mentioned cooking liquid, for example, caustic soda or sodium citrate is used. The pulp used for the pulp is bast *fibers, culm 11 fibers, and broken skins (peaches, hemp, etc.). Wood soda pulp produces paper that is light, bulky, opaque, and has a uniform texture.

Dissolved pulp is produced by carefully refining and bleaching pulp made by adding water and cooking it in a cooking liquor containing caustic soda and sodium sulfide as its main ingredients, and using N wood (softwood wood), L wood (Buddha statue wood), miscellaneous wood, etc. as raw materials. The special feature of the kraft pulp method is that the waste liquid is concentrated and used as a cooking chemical, and sodium sulfate is added to make up for the shortage.

Sodium sulfate is reduced in the leg cords created by carbonization of wood components and becomes sodium sulfide. The cooking liquor used is a mixture of fresh liquor (white liquor) made in the pharmaceutical process (recovery process) and an appropriate amount of cooking waste liquor (black liquor). At the end of the cooking process, it is ejected into a blow tank (t or diffuser) to separate it from waste liquid, and the pulp is collected and washed. Iori is burned to create sulfite ganu, which is sent to a pharmaceutical tower (height 50-457) filled with limestone, and water is dropped from the top of the tower to form bisulfite Ca (H80m)* solution. do. Add free sulfuric acid to it, fc mH@SO3+ nC
a (H8Os) m +H*0 becomes the cooking liquor.

In addition to the calcium base, magnesium and ammonium may also be used. After the binding process of the printing paper 1 is completed through the above process, as shown in Figure 6, after turning the printing paper 1 on its back as in the conventional book binding or temporary book binding process. The bookbinding is completed by performing processes such as finishing cutting for edge decoration and applying the exterior.

It should be noted that drying can be carried out more quickly if hot air is blown onto the back surface in addition to the above-mentioned (ultrasonic) vibration application.

As described above, the present invention applies pressure to one side or both sides of the stacked sheets of paper to make the back side part fluffy, and then applies cooking liquid to the back side part, and then applies a cooking liquid to the back side part. Before the applied cooking liquid dried, we performed an operation to entangle the fuzz, and then applied (ultrasonic) vibration to the back of the cup to dry and solidify the cooking liquid before binding. In addition to the simple binding equipment, there is no need for binding threads or wires, which saves resources, and the binding is perfect and does not come off even when pushed apart.
