Processing method for minitype hardcover round back book

Abstract

The invention provides a processing method for a minitype hardcover round back book, which comprises the following processes: matching a section; placing the section in an adhesive binding machine; conducting back milling and groove pulling on the section, wherein the groove depth produced by the groove pulling is 0.2-0.5 mm; brushing certain glue on a spine of the book being subjected to the back milling and the groove pulling, wherein the brushing of glue is conducted in twice, the thickness of the first glue is 0.35-0.55 mm, and the thickness of the second glue is 0.5-0.75 mm; heating and rounding formation, wherein the heating temperature is 38 DEG C, the heating time is 32 S, and then the book is formed by rounding; finally, conducting paper bottom gauze packaging. through the adoption of the method, the minitype book is allowed to be kept to be bound firmly during round back threadless deluxe binding, so that pages are not fell apart; meanwhile, the binding of a plurality of minitype books can be conducted by one same perfect adhesive binding machine, so that the work efficiency can be improved and the cost is saved.

Description

technical field [0001] The invention relates to a method for processing books, in particular to a method for processing miniature hardcover round endorsements. Background technique [0002] Round-back hardcover is made after signatures are sewn, which is a common process for hardcover books. The advantage of this technique is that the signatures have high fastness, are easy to pick up and round the ridges, and the circles are full after writing. The disadvantage is that thread locking is labor-intensive and time-consuming, and requires a large amount of cotton thread, which is high in cost; And through the processing of the new technology of wireless hardcover, the signatures, like wireless perfect binding, use the perfect binding machine to mill the back and brush the adhesive, and then enter the hardcover process. [0003] Since the perfect binding process is used for round-back hardcover, it depends on the thickness and plasticity of the adhesive layer. The commonl...

Problems solved by technology

However, this production process has very high requirements on the time after perfect binding. Once the PUR glue and water are cured, the rounding and ridges will not be possible, and in-line production is required. Therefore, the current use of PUR for wireless round back hardcover still has limitations. Not suitable for mass production

[0004] At the same time, the processing method of round back wireless hardcover of books is generally applied to signatures of normal size such as 16K, 32K and 64K signatures. For some miniature signatures such as signatures whose size is much smaller than 64K The processing method of round-back wireless hardcover in the prior art will cause the book to be unreliable and easily cause the pages to fall off
