Definitions

  • This invention relates to a book or booklet including a leafblock and a cover part comprising at least a front cover and a back cover and possibly a back and formed of sheet or web material which is board, cardboard, paper or the like by folding and bringing the material layers fitted against each other to adhere to one another, whereby the cover part is formed by folding a one- or multi-layer sheet or web material blank in one piece against itself at all free edges of the front cover and back cover and by making the at least two material layers folded against each other to adhere to each other by means of adhesive material.
  • the invention also relates to a book or book cover or a folder comprising at least a front cover and a back cover and possibly a back and formed of sheet or web material which is board, cardboard, paper or the like by folding and bringing the material layers fitted against each other to adhere to one another, whereby the cover or folder is formed by folding a one- or multi-layer sheet or web material blank in one piece against itself at all free edges of the front cover and back cover of the cover or folder and by making the at least two material layers folded against each other adhere to each other by means of adhesive material.
  • the invention relates to a method of making a book or booklet cover or a folder of sheet or web material which is board, cardboard, paper or the like by folding and making the material layers fitted against each other adhere to each other, whereby a one- or multi-layer sheet or web material blank in one piece is folded at all free edges of the front cover and back cover of the cover or folder against itself and the at least two material layers folded against each other are made to adhere to each other by means adhesive material.
  • books are divided into two groups, hard-bound or hard-covered and paperbacks, respectively, according to how they are bound.
  • the front cover and back cover of hard-covered books are formed with a rigid core of cardboard which is lined both inside and outside. Outside lining is done by folding the edges of the lining material around the edges of the cardboard core and by glueing together the lining material and the cardboard core. The inner lining again is glued onto the cardboard core to lie on the edges of the outer lining. Inside lining is done only in a further process, that is, at a casing-in stage when combining the leaf part and the cover of the book.
  • the books hve been bound so that the back part of the book contains a sleeve or other structure between the cover and the leafblock or bookblock formed by leaves bound together, to keep the back part of the cover off the back part of the book's leaf part.
  • the cover edges thus produced are very wear-resistant. However, binding requires many different work steps.
  • Paperbacks again are bound by glueing together the book leaves at their back part to form a bookblock or block and by glueing together the bookblock and the back of a cover part made of board.
  • An improvement on this earlier paperback is described in Patent Publication EP-A-0077795.
  • a sleeve is used in the back or spine of the book which when flattened is slightly wider than the back. An open fold is thus left on both sides of the back allowing the book to be opened so that it also remains open and the back part of the cover will not tend to break.
  • a problem with paperbacks has been the tendency of cut board edge surfaces at the cover edges to fray and crack up.
  • Two other examples of the prior art are published in DE-A-2420926 and in US-A-4615541.
  • the object of the present invention is to achieve a method of making books as advantageously as paperbacks but wear-resistant like hard-covered books.
  • the product's degree of processing can be raised to a level replacing the production of hard covers.
  • the method in accordance with the invention can be applied with conventional machines of the packaging industry used for manufacturing casings used to package various consumption articles. These machines can be used for folding and glueing book covers in accordance with the invention. Finished covers can then be delivered for binding into a leafblock, the leaves of which have been printed and bound into a bookblock at the printing house. In this way, the book is made at considerably more advantageous costs than when using traditional methods.
  • Covers in accordance with the invention which have properties of hard covers can be made by using a cover blank in one piece and there need not be any separate stiffening core part in the cover. Sufficient rigidity is obtained by means of edge folds and by glueing two folded layers of the cover blank against each other. Folding of the edges also results in durable edge surfaces which do not break or crack up easily.
  • a product comparable to a hard-covered book can be made by using a book-making process intended for paperbacks. The result is a cover with high wear resistance.
  • suitable applications for a cover in accordance with the invention for example, text books, manuals, telephone directories etc.
  • a cover in accordance with the invention can also be made for conventional production processes specialized in hard cover production. Traditional cost burdens relating to cover production are hereby avoided.
  • a previously known hard book cover is formed of a cardboard core 1 of the front and back cover, of a back 2 and of a covering material or lining 3.
  • the cardboard used may be, for example, about 2 mm thick grey so-called woodpulp board.
  • the back board is usually of a thickness less than 50 % of the cover cardboard thickness.
  • the lining material used can be paper, cloth, plastic and their combinations and mixtures.
  • the lining material sheet 3 to be glued onto the outer cover surface is of such a large size that the lining can be folded over the free edges of the cardboard core. The cut cardboard edge surface is thus hidden.
  • An inner lining (not shown in the drawings) is glued onto the inner cover surface.
  • the inner lining is done at the casing-in stage when combining the leafblock and the cover.
  • the book's so-called flyleaf is hereby glued at its outer side to the inner cover surface and it forms a lining for the inner cardboard surface.
  • a book cover can be made of relatively thin board, which is generally used in different package cases.
  • cover blank 4 all edges of cover blank 4 are provided with horizontal and vertical scorings and/or groovings 5, 6, which separate the cover side laps 7 from the remaining part of the blank.
  • Back part 8 is also separated from the cover part by groovings 9.
  • the back part groovings can be made either when making the cover or later in the production process of the bookbindery.
  • the corners of the blank are chamfered at the corners of edge groovings 5, 6.
  • a book cover as shown in Figure 2b is made of the blank by folding all side laps 7 of the blank along groovings 5, 6 against the inner surface of the cover blank and by glueing together the opposed two board layers.
  • the folded edges 7 stiffen the whole periphery of the finished cover. They also have the effect that the cut board edge surfaces will not be edge surfaces in the finished cover. This prevents ply separation and tearing of cover edges as well as other changes in the board cross-section when using the book.
  • book manufacture takes place on a traditional adhesive binding line used in the manufacture of paperbacks.
  • the bookblock must be cut to its final product size before binding it into the cover.
  • Figures 3a and 3b show a similar solution where a sleeve 10 is also used to have a loose back in the finished book.
  • sleeve 10 is glued to the inner side of the cover part.
  • the sleeve width when flattened is preferably slightly more than the width of the book back, whereby a fold is formed on either side of the back to make it easier to open the book.
  • Figures 4a and 4b is a variation of the solution shown in Figures 2a and 2b.
  • all edges of the cover are folded.
  • parts 11 to be folded around the vertical cover edges are so wide that they extend to the connection point between the back and cover.
  • Side seamings provide the whole cover periphery with folded edges and a durable periphery is obtained. This prevents ply separations in the board and other such changes of the board's cross-sectional shape when the book is in use.
  • the cover is double and sturdy. The book can be made either on an adhesive binding line or on a hard-cover line.
  • the solution shown in Figures 4a and 4b can be improved further by using a sleeve 10 in the back as shown in Figures 6a and 6b to prevent the back from breaking.
  • the folded parts may either end at the connection point between the cover and back or they may extend under the sleeve.
  • Figures 6a and 6b show a variation wherein parts 11 to be folded to the inside and which extend to the back are chamfered at their free vertical edges 12. This makes it easy to round off the back, because the seam will not tend to break the topmost board layer during mechanical rounding-off, where depending on the material one may use heat as a factor promoting rounding-off.
  • the edge chamfer of the bent parts distributes the risk of breakage during bending of the board evenly to every part of the back structure.
  • the book is given the same appearance as a rounded-off hard-covered book.
  • the book is made on a hard-cover line if the back is rounded off. If no rounding-off is done, an adhesive binding line may be used, whereby the bookblock is run to its final product size before casing-in.
  • part 11' which is folded around the vertical edge of the first cover, is so wide that it extends over the back to the second cover, all the way to the folded edge of the second cover.
  • the part to be placed at the back part is separated by groovings 13.
  • the cover is thus stiffened by one fold part and the back part is seamless.
  • the second cover can also be made without any part to be folded.
  • Figures 8a and 8b show still another variation, wherein the cover corners are rounded off following the rounding-off of outer side corners done in the bookblock.
  • all the side fold alternatives and sleeve structures described above may also be used.
  • the rounded-off corners provide the weakest cover parts with mechanical wear resistance. Rounding off can be done mechanically on hard-covered products. Earlier this was possible only with plastic products or as a multi-stage process with traditional hard covers.
  • Figure 9 shows a blank configuration, according to the invention, having two groovings 9, 9' at a distance from each other on both sides of back part 8.
  • Foldable side laps 7 are dimensioned so that they cover the whole area of both the front cover and the back cover, except the surfaces between each grooving pair 9, 9' of the back part. At these surfaces there are gaps 14 between the side laps. This results in a thinner part at the bending point of the front cover and back cover which makes it easier to open the book.
  • the inner cover surfaces may be lined with paper. If desired, different kinds of openings may be easily made in the covers by punching, through which openings, for example, part of the book's flyleaf can be seen. In this way various additional effects can be made to alter the book's appearance.
  • the invention can be applied not only when making book covers and books but also when making folders.
  • the material used for covers and folders may also be cardboard or paper, besides board.
  • the sheet material may also be multi-layered and also a combination of these materials.
  • a board-plastic laminate for example, may also be used.
  • Paper may be used, for example, in the application shown in Figure 7, whereby the paper folded double in the finished cover is equal to the thickness of unfolded board.
  • the layers can be adhered to each other by heat-sealing the plastic-coated laminate surface against itself.
  • the invention may also be applied to booklet-type products having no proper back part.
  • the blank may be either sheet material or web material drawn directly from the roll.
