End paper arrangement and method for forming the front and back end paper of a book

Abstract

An end paper arrangement and method for forming the front and back end paper of a book wherein the end paper arrangement comprises an inner sheet and outer sheet which are fastened on one side against each other over at least one area so that an unfastened area remains between the fastened areas. The unfastened area forms a tunnel for the spine of the book. On that side of the inner sheet which is opposite to the fastened side there is an adhesive surface on both edge parts, and there is an adhesive-free area between the adhesive surfaces. On the side of the outer sheet which is opposite to the fastened side, there is an adhesive surface on both edge parts, and there is an adhesive-free area between the adhesive surfaces. The method performs the assembly set forth in the arrangement.

DETAILED DESCRIPTION

(14) FIG. 6 shows an end paper arrangement 30 for the forming of the front and back end paper of a book. The end paper arrangement 30 comprises an inner sheet 33 and an outer sheet 35, which are fastened on their one side against each other over at least one area so that an unfastened area remains between the fastened areas, in which unfastened area the inner sheet 33 and outer sheet 35 form a tunnel 39 for the spine of the book.

(15) On that side of the inner sheet 33, which is opposite to the fastened side, there is an adhesive surface 32 on both edge 25 parts, and there is an adhesive-free area 38 between the adhesive surfaces 32.

(16) On that side of the outer sheet 35, which is opposite to the fastened side, there is an adhesive surface 36 on both edge parts, and there is an adhesive-free area 137 between the adhesive surfaces 36.

(17) In the end paper arrangement 30, the adhesive surfaces 36 on the side opposite to the fastened side of the outer sheet 35 are protected by means of a uniform protective sheet 37, such as siliconised paper.

(18) In end paper arrangement 40, FIG. 7 which is alternative to the end paper arrangement 30 (cf. FIG. 6), each of the adhesive surfaces 36 on the side opposite to the fastened side of the outer sheet 35 can be protected by means of their own at least one protective sheet 37, such as siliconised paper.

(19) At the tunnel 39, there can be an area 99 containing hot melt on at least one side that points away from the tunnel 39in other words in the position indicated by FIG. 6 or either at the adhesive-free surface 38 above the inner sheet 33 and/or at the adhesive-free surface 137 of the outer sheet 35, which area 99 containing hot melt is advantageously strip-like.

(20) Each of the siliconised papers 37, 31 or part of them can have a flap 41.

(21) In the method for the forming of the front and back end paper of a book: a bundle 15 of sheets 65 are placed over the end paper arrangement 30, 40 (cf. FIG. 8 or 14) and fastened to the end paper arrangement 30, 40 (cf. FIG. 9, FIG. 15 and FIG. 16); the bundle 15 is glued from its first outermost sheet to the adhesive surface 32 opposite to the fastened side of the inner sheet 33 of the end paper arrangement 30, 40 and from its second outermost sheet to the adhesive surface 32 opposite to the fastened side of the inner sheet 33, which adhesive surface 32 is on the other side of the adhesive-free area 38 (cf. FIG. 9); the end paper arrangement 30, 40 and the bundle 15 are trimmed to the same line T (cf. FIG. 10); the first cover of the covers 22 of the book is glued from its 30 inner side to the adhesive surface 36 opposite to the side fastened to the outer sheet 35, and the second cover is glued from its inner side to the adhesive surface 36 opposite to the side fastened to the outer sheet 35, which adhesive surface 36 is on the other side of the adhesive-free area 137 (cf. FIG. 11); in which case the outermost sheets of the bundle 15 form the front end paper 51 and back end paper 52 of the book 23 (cf. FIG. 5 13). In the book 23, there is a space for movement at the spine edge of the covers 22 and bundle 15 thanks to the end paper arrangement 30, 40. This prevents the tearing off of the bundle from the covers 22 and enables the manufacture of high-quality hardbound books 23 so that the front end paper 51 and back end 10 paper 52 can be printed at the place of use using a freely selectable and printable grade, material and colour.

(22) According to the first embodiment of the method, the sheets 65 in the bundle 15 are fastened to each other before placement over the end paper arrangement 30, 40. The sheets 65 are fastened to each other most advantageously by gluing, most preferably by means of hot melt such as EVA hot melt or PUR adhesive.

(23) In addition to this, the sheets 65 and end paper arrangement 30, 40 can be fastened to each other after placement on top of each 20 other by piercing by means of a number of piercing devices 64.

(24) According to the second embodiment of the method according to the present invention, the sheets 65 in the bundle 15 are not yet fastened to each other when placed over the end paper arrangement 30, 40, but the fastening to each other is only carried out after the placement of the sheets 65 and end paper arrangement 30, 40 on top of each other by piercing by means of a number of piercing devices 64 (see FIG. 16).

(25) The piercing devices 64 used are best staples. The staples are stapled most preferably in the direction of the tunnel 39. The sheets 65 can be folded with respect to the center line of the book 63, in which case the staples are best stapled to the folding line.

(26) The piercing devices 64 are most preferably fastened at the tunnel 39, most advantageously in a cross direction with respect 35 to the direction of the tunnel 39 in the middle of the tunnel 39 or otherwise in the center area. In this case, a movement area 66 is formed for the piercing devices 64 between the covers 22 of the book 63 and the end paper arrangement 30, 40, enabling the movement of the piercing devices with respect to the covers 22 of the book when the sheets 65 are browsed and when the covers 22 of the book 63 are opened or closed. When the book 63 is browsed, the tunnel 39 reduces the stresses exerted on the adhesive bonding (label adhesive 36) between the cover 22 and outer sheet 35.

(27) FIG. 14 and FIG. 15 present that the book 63 has three sheets 65. In practice, the number of the sheets 65 can be other than 3. The book 63 can have at least two sheets 65 (for example if the book 63 is a restaurant menu), but there can be more sheets 65, for example 3 to 20 sheets.

(28) The invention should not be understood to be limited only by the below claims, but the invention is to be understood to include all their legal equivalents and the combinations of the embodiments presented.
