MACHINE AND PROCESS FOR BINDING OF BOOKS FOR LAY FLAT LOOK

The following specification describes the invention TECHNICAL FIELD:

The present invention relates to method whereby prints or paper undergo process of window cutting, punching and stapling resulting in step binding and machine thereof. This process gives the bound book a lay flat look when opened. The machine enables the process of window cutting, punching and stapling in the same machine.

BACKGROUND AND PRIOR ART:

Photo albums, books and magazines are bound in a manner where multiple pages are held together in a book block. These multiple sheets of papers or folded papers are held together by different methods which includes sewing, saddle wire stitching, stapling, spiral binding, velo bind, plastic comb binding, perfect binding. In the case of spiral binding, velo binding, plastic comb binding and perfect binding the binding is accomplished with a hard plastic or metal wire holding the plurality of sheets together at the spine. In the case of plurality of paper which are sewn together the book is subjected to a binding process wherein the spine of the stitched block is attached to a hard cover using glue or other treatment.

The conventional method for the binding of plurality of pages with double sided prints is done manually with little technical assistance of the binding machine wherein the prints are stapled manually and when the book is opened a slight radius in the middle of two prints is present. This hampers the vision in the print detail, as the print cannot be viewed properly at the point of radius. The plurality of pages when bound together by stapling, sewing or perfect binding causes the pages to be held firmly together at the spine which causes the book to form an arcuate configuration near the spine when opened resulting in difficulty in viewing the text or picture adjacent to the spine. At times prints are made away from the spine so that its view of images is not obstructed on opening of the book which results in reduction of printable area. The reader is further required to exert additional force on the page in the direction of spine to extend the page outward to view such text or image which could damage the binding or result in tearing of pages. This causes difficulty in reading and could lead to loss of valuale information and durability of the book

In manual binding the prints are stapled manually which results in lack of perfection and the book cannot open flat resulting in lack of full view of book, photograph or album.

Therefore it has become necessary to develop a method which would give the books a lay flat look when open and are also firmly held at the spine.

Therefore it has become necessary to develop machines which would give the books a lay flat look when open and which are cheap and can be installed easily.

. Accordingly, an object of the present invention is to provide for a method which would give the books a lay flat look when open and are also firmly bound at the spine.

It is an object of the present invention to provide for machine which would give the books a lay flat look when open and are firmly bound at the spine.

It is an object of the present invention to provide for method and machine and apparatus which are economical and easy to use, giving a product which has high visible quotient, durability, accuracy and finesse in binding and of superior quality.

SUMMARY OF THE INVENTION:

The present invention provides for method to bind the book in a manner such that the book gives a lay flat look when open and a machine for accomplishing the said process. The process could be applied to a variety of documents including albums, catalogue, photographs and papers.

The pages are introduced to a window cutting process wherein spaced rectangular slits are opened parallel to the spine of the bundled pages at regular intervals. The slits are made at a predetermined space from the spine end of the page such that there is sufficient space for stapling and binding.

The pages, if they form part of a photo album, catalogue or such can undergo the process of thermal lamination in a separate machine through know known methods and machine.

The pages are introduced to a punching assembly in the machine whereby holes are created at a predetermined interval in the space between the window cutting slit and the spine such that there is sufficient space for the stapling process. The holes are punched in a manner such that for the first half of the plurality of pages the holes are punched with a regular reducing distance from the spine. For the second half of the plurality of the pages the holes are punched in a manner which is at an regular increasing distance from the spine to the last page of first half which results in V shaped spine such that the pages at the centre of the book form the lower tip of v and the pages at the ends form upper two tips of v. The pages are then introduced to the stapling assembly wherein the pages get aligned with a pin and firmly attached by stapling. The plurality of pages is transported from one assembly to the other manually. The book is then trimmed at the edges, cover affixed by know processes and ready for use with a lay flat look.

the paper becomes heavier and unwieldy than earlier resulting in difficulty in arranging and matching the window cutting or slits of the paper in one line and level which is achieved by die hole punching 14, in which a die cause holes to be punched on the papers at a predetermined spacing on the prints in a forward and reverse action and vice-versa. This can be achieved manually or through a method. The die punching 14 processes can be regulated with a digital control panel. The machine process in a manner that the load of multiple pages gets balanced and load keeps on shifting to the other pages. In an embodiment of the machine for carrying out the process, a digital program also achieves the purpose in a seamless manner. The operator is required to enter the number of pages with different parameters including the length of the page, distance required from the spine 12 to the window cutting, die punching and stapling. This process results in the giving a finesse at edges with the window cutting 1 1.
