Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a signature integrated block which is carried out prior to the bookbinding of books, notebooks, catalogs, forms and the like.

[0002]

2. Description of the Related Art Conventionally, a signature is formed from a sheet or roll on which a fixed number of pages are continuously printed, and the signatures are temporarily stocked for each page group of the same series. Re-separate each signature group and use it for the loader,
In the loader, the signatures were taken out one by one from each signature group and stacked one by one to form a signature stacking block of continuous pages, which was then subjected to the bookbinding process.

[0003]

According to the above conventional example, a stock group is formed for each signature of the same through page, and signatures of the same through page (for example, pages 1 to 16) from the first stock group are formed. The group is re-separated, and then the signature group of the same through-page (for example, pages 17 to 32) is re-separated from the second stock group, and the same re-separation is repeated for the loader. The signatures are taken out from the group one by one, and the signatures are piled up. The signature accumulation block of the continuous pages (for example, pages 1 to 96) is completed for the first time in the bookbinding process. The formation of the Ding integrated block is extremely complicated and inefficient, which imposes a heavy burden on personnel and labor, resulting in a high cost.

[0004]

Therefore, according to the present invention, a plurality of signature forming lines are installed in parallel, and the signature forming lines are connected to the sending side of each signature forming line. To provide a method for forming a signature stacking block, in which a stacking line is arranged to form a folded stacking block of through-pages in which the above-mentioned signatures are aligned to each other and which can be directly connected to a bookbinding process. is there.

[0005]

For example, in the first signature forming line, the first signature of the same through page (for example, pages 1 to 16) is formed, and in the next second signature forming line, the same signature page (for example, 17 to 32).
2nd signature of page) and each signature is formed in the same manner, and the 1st to nth signatures thus formed are provided to the signature stacking line, and the signature stacking is performed. In the line, a second signature is sequentially stacked on the first signature, a third signature is sequentially stacked on the second signature, and finally a predetermined number of signatures are sequentially stacked in a page order. An integrated block is formed, which can be immediately subjected to the bookbinding process.

Therefore, the work of forming the signature stacking blocks stacked on the through-pages can be significantly simplified and the labor can be saved, and the work efficiency can be greatly improved to reduce the cost.
