(54) METHOD OF STRAPPING BOOK BLOCKS

The invention relates to printing production, namely, bookbinding and binding, and can be carried out in enterprises producing books and magazines using the method of glueing and sewing.

There is a known method of fastening book blocks, which consists in applying sheets of composition on an adhesive base from two sides, folding sheets, compiling notebooks into a block, adhesive binding of notebooks into a block and trimming the block with three c-ioron tl 1.

On a sheet of paper before folding

they are applied on two sides of the adhesive composition, they are located symmetrically with the fold lines and at a distance from one another equal to the size of the trimmed folds.

The existing method of fastening book blocks does not allow automating the process of applying strips of the composition on the adhesive base, which reduces the bonding performance.

The purpose of the invention is to increase bonding performance.

The goal is achieved by the fact that according to the method of bonding

book blocks, consisting in applying from two sides to sheets a sheet, los of a composition on an adhesive base, folding sheets, completing notebooks into a block, adhesive bonding of notebooks into a block and trimming the block from three sides, the composition on a glue base is applied to the parallel edges of the sheet , and the binding of notebooks in the block produces 10 tons of these edges.

FIG. 1 shows schematically the application of the adhesive composition on a paper web; in fig. 2 - applying adhesive composition on paper

15 sheet; in fig. 3 - sheet after folding (. Notebook, in Fig. 4 - the spine of the block after applying glue; Fig. 5 - view of the radicular zone, made by the proposed method,

20 when revealed.

FIG. The 1 and 5 positions are marked with a paper web 1, strips of glue 2, a device for applying glue, a sheet of 4 paper, a notebook 5, a base adhesive layer 6, a sheet 7 in the block.

The essence of the proposed method is as follows.

 On the edges of the paper web 1

30 strips of 2 glue are applied using device 3 (Fig. 1). The application of the adhesive composition can also be carried out on the edges of the paper sheet 4. Then the sheets are folded f in FIG. The dotted lines in Figure 2 show the folding lines of sheet L. As a result of folding, notebook 5 is obtained, in which glue strips are located on one of the fold-free sides (Fig. 37. This side of the notebook is the root zone of the future block. After folding and trimming the folds onto the back The main adhesive layer is b (Fig. 4). When bending the sheets 7, the proposed construction of the spine of the block (Fig. 5 allows the adhesive layer between the sheets to easily change its position without destroying the glue in the spine area of the block. Performing loose-leaf bonding in the proposed method will significantly simplify the technological process of manufacturing
