SU925681A1 - Method of stichless binding of inner books - Google Patents

Description

The invention relates to printing and its production, namely, bookbinding and bookbinding, and can be carried out in enterprises producing books and magazines by the method of glueing. The known method of loose-leaf bookbinding of book blocks includes the folding of sheets, picking up notebooks, mechanical processing of the spine of the block and adhesive bonding of the spine. Mechanical treatment of the spine of the block includes its milling. When the cutter enters the processed material and leaves it, the quality of the processed surface is much worse than in the steady state. (Milling the middle of the block). This phenomenon is observed when milling any material for a book block due to the low stiffness of the paper and the lack of communication within the material (separate notebooks and sheets), the unevenness of the quality of processing is particularly pronounced. All) The consequence of such processing is that the shear sheets have different micro unevenness, the adhesive bond is unequal and the book block is easily destroyed when reading. The aim of the invention is to improve the quality of the bonding of the block. The goal is achieved by the fact that in the method of loose-leaf book stitching, including folding sheets, completing notebooks, mechanical processing of the spine of the block and adhesive bonding of the spine, before the mechanical treatment of the spine of the block, an adhesive layer is applied. The essence of the invention is as follows. After folding and compiling notebooks to the spine of the block with the help of a special device,

glue cocraa. At the same time, the process of cutting the root of the block and improving the processing conditions of the block significantly improves the cut quality of the root, as in this case the notebooks and the sheets of the block are interconnected by glue and represent a monolithic system. In addition, milling on the adhesive film changes the dynamics of the milling process and allows an equal height and roughness to be achieved along the thickness of the block. It should be noted that by applying adhesive to the lattice area of the block, milling performance can be improved by increasing the feed rate of the block to the mill, as well as improving the quality of other types of mechanical processing, such as rounding the root and masking. Using this method of processing a book block improves the conductors for improving the quality of glue bonding of a block. Claims method of loose-leaf book binding; blocks, including folding sheets, completing notebooks, machining the block root and adhesive bonding of the root, different from the fact that, in order to improve the quality of bonding, before machining, the block grille applies an adhesive layer.
