Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention may be better understood from the following non-limiting description of a preferred embodiment, in which:

(2) FIG. 1 is a perspective view of a book block adapted to be bound to a book cover by one embodiment of the present invention;

(3) FIG. 2 is a perspective view of a book cover for binding the book block of FIG. 1, with adhesive members; and

(4) FIG. 3 is a side elevation of a bound book with the cover of FIG. 2.

DETAILED DESCRIPTION OF THE DRAWINGS

(5) It should be noted that although the present invention is intended to be applied to bind heavy gloss paper such as that used for printing photos, it may be used to bind all types of paper.

(6) Referring to FIG. 1, a book block 10 comprises a plurality of loose sheets being bound together. Preparation of the book block 10 includes the initial steps of collating and aligning the loose sheets intermediate the front and back fly sheets 14 and 16 to form a loose aligned pile. A wire or thread 11 is then used to securely stitch the loose pile together via a stitching machine along spine edges 52 of the pile.

(7) The book block 10 is to be bonded to a book cover 20 to form a book. Turning to FIG. 2, the book cover 20 has front and back panels 22 and 24 which are joined by a spine panel 26. The book cover 20 includes two cardboards 28 and 30 and a spine 32, all of which are within a case 34. In the present embodiment, the case 34 includes an inner layer made of a paper liner 36 and an outer layer made of a fabric 38.

(8) The spine panel 26 includes a spine 32 flanked by two hinge areas 44 and 46 which are made of pliable material. The spine 32 is configured so as to suit book blocks of various thickness. It is contemplated that the spine 32 is provided in three sizes, namely 7 mm, 9 mm and 12 mm. The spine 32 is capable of accommodating a book block having a thickness smaller than itself. In the case of binding a book block that is substantially thinner than the spine 32, the spine 32 will bow outward to a certain degree upon completion of the binding process.

(9) To enable bonding of the book block 10 to the cover 20, first and second adhesive members 40 and 42 are applied to the spine panel 26. Each of the adhesive members is a strip of acrylic mass adhesive having a thickness of substantially 0.05 mm and a width of substantially 12 mm. This involves having the cover 20 in an unfolded state with the front, spine and back panels 22, 26, and 24 respectively juxtaposed on a plane, and adhering the first and second adhesive members 40 and 42 onto the hinge areas 44 and 46, respectively. As shown in FIG. 2, the spine 32 is intermediate the first and second adhesive members 40 and 42 which lie alongside and are parallel to one another.

(10) Each of the adhesive members 40 and 42 has a backing material 48, 50 which preserves the adhesive members 40 and 42. When needed for use, the backing material 48, 50 is peeled off each of the adhesive members 40 and 42. The removal of the backing materials 48 and 50 exposes the adhesive on the adhesive members 40 and 42 respectively and hence the next step should be carried out reasonably quickly.

(11) Referring now to FIG. 3, the next step is to bring the front fly sheet 14 into contact with the front panel 22 in such a way that a margin of the front fly sheet 14 overlaps the first adhesive member 40. This involves aligning the edge 52 (refer back to FIG. 1) of the book block 10 with the first adhesive member 40 and placing the book block 10 onto the front panel 22 in such a way that the margin indicated by A-A (see FIG. 1) of the front fly sheet 14 makes contact with the first adhesive member 40. As this happens, the book block 10 is rested on top of the front panel 22.

(12) To complete the binding process, the back fly sheet 16 is to be put into contact with the back panel 24 so that a margin indicated by B-B (refer FIG. 1) of the back fly sheet 16 overlaps the second adhesive member 42. This involves turning the back panel 24 towards the book block 10, aligning an edge 54 of the back panel 24 with an edge 55 of the front panel 22, and folding the back panel 24 onto the back fly sheet 16. To consolidate the bond between the adhesive members 40 and 42 and the respective fly sheets 14 and 16, the first and second parts of the spine panel 26 are to be pressed on firmly.

(13) It should be noted that each of the front and back fly sheets 14 and 16 is made out of synthetic paper with a minimum thickness of 14 millimeters. This configuration can prevent the fly sheets 14 and 16 from being torn as a result of bearing the weight of the book block 10.

(14) Now that a preferred embodiment of the present invention has been described in some detail, it will be apparent to a skilled person in the art that the binding method may offer at least the following advantages: 1. it is easy to apply enabling provision of a do-it-yourself type of service; 2. it produces a book which is aesthetically pleasing with no exposure of any binding components; and 3. it is economical to implement.

(15) Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. For example, the method of the present invention need not be carried out in a particular order. The book block may be adhered to the back panel first before bonding the front panel to the book block, as one variation. All such variations and modifications are to be considered within the scope and spirit of the present invention the nature of which is to be determined from the foregoing description.

INDUSTRIAL APPLICABILITY

(16) The binding method of the present invention is industrially applicable in that it enables provision of a do-it-yourself type of service for the production of a book which is aesthetically pleasing without exposing the binding components.
