Description

COMPACT BOOK BINDING MACHINE

FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION

Traditional book manufacturing included a number of individual stages to bring about the finished products, that involved a great deal of planning and individual processing, including printing the book block, cover, trimming the pages to size, binding and pressing the cover onto the book block. The book binding process is preceded by a manual and lengthy set up process for each individual books to account for book dimension, where the individual process for example printing press, binding machines are individually set up to accommodate the specific dimension of a book and stages of book binding. Current technological advancement and

development in particular with printing technology has led to the production of printing on demand systems (herein referred to as 'POD'). And cost effective short runs of books, booklets, photo albums and etc (range from a single copy and up to few hundred copies).

Development of POD systems requires automation for each of the different stages in the book manufacturing process. Typically POD systems produce soft cover bound books that comprise a stacked plurality of text printed pages (herein referred to as a book block) having one edge which is referred to as the spine with a cover of a suitable cover stock that is generally thicker (heavier) than the text pages comprising the book block.

A milling station is used to prepare the spine of the book block to be milled and/or roughened by a driven blade so as to improve the spines' ability to accept the adhesive that would bind the cover to the spine of the book block. Prior to the application of adhesive the pages of each book block are usually jogged by specially developed machines so as to insure that the edges of the pages are properly aligned with one another.

Then, the book block is transported to an adhesive application station where adhesive is applied to the spine. The book block was then moved to a binding station at which the cover had been positioned and the spine of the book block with adhesive applied thereto was brought into engagement with the inside of the cover at a desired location and the cover was clamped to the book block proximate the spine so as to adhesively bind the cover to the book block. The adhesive application station may be provided with a rotary adhesive application wheel or drum that is at least partially immersed in a bath of cold or hot melt adhesive that may then applied to the spine of the book block.

The cover, which is usually pre-printed, has a front portion that overlies the front of the book block, a back portion that overlies the back of the book block, and a center portion spanning across the spine of the book block. During the binding process a suitable adhesive is applied between and/or directly on the spine of the book block and/or the inside face of the center portion of the cover, as described above. The cover is then folded around the front, spine, and back of the book block and is firmly clamped to the book block proximate the spine during assembly. In this manner, the adhesive is firmly pressed between the spine of the book block and the inner face of the center portion of the cover to properly adhere and/or couple the cover to the book block while simultaneously adhering and/or coupling the pages to one another .

Optionally, the bound book may then be transferred to a trimming station at which excess margins were trimmed from one or more and preferably from three sides of the book so as to produce a book of a predetermined finished size . SUMMARY OF THE INVENTION
