Definitions

• the subject of the present invention is a hard-cover paperback book which comprises a book block consisting of leaves joined together at their spine edges as well as a hard cover fastened to the book block.
• the cover When a conventional hard-cover book is manufactured, the cover is glued, both at the front cover and at the back cover, onto the first and the last leaf of a ready-cut book block over the entire faces of these leaves, whereby the crepe layer glued onto the spine of the block is, by means of its edge stripes, glued between the front cover and the first leaf and between the back cover and the last leaf, respectively.
• the cover can be connected with the book block firmly by the intermediate of the crepe.
• the leaves of the book block glued onto the front and the rear cover cover the inside face of the front and the rear cover and thereby give the cover a tidy appearance.
• the spine part of the cover is loose from the spine part of the book block and from the crepe fastened to same.
• the book block with particular foreleaves, to which the front and the rear cover are fastened in stead of being fastened to the first and last page of the book block.
• the aligning and the fastening of the hard cover to the book block requires special machinery, which is slow-moving in view of ensuring adequate precision of work.
• the step of providing the hard-cover books with covers makes the operation of the production line considerably slower.
• the step of providing the book with covers does not cause any retardation, but the soft cover and the book block can be aligned rapidly and precisely in the glue-binding machine.
• the soft cover is then fastened by glueing onto the spine of the book block, and usually also onto the first and last leaf of the book block along narrow glue stripes placed at the spine edges of the said leaves.
• the object of the present invention is to provide a hard-cover paperback book which eliminates the above drawbacks and which permits the manufacture of a hard-cover book by means of the glue-binding technique that has been so far used only in the manufacture of soft-cover books.
• the hard cover is made of two parts and comprises a) an inner, soft inner cover, which extends around the spine of the book block and which is, at its front and back portions, fastened to the book block along fastening stripes placed along the spine edges of the first and last leaf of the block so that the spine portion of the inner cover between the said fastening stripes is loose from the spine of the book block, and b) an outer, hard outer cover, which extends around the spine of the inner cover and whose edges extend beyond the edges of the inner cover and which is, at its front and back parts and at its spine, throughout fastened to the corresponding portions of the inner cover.
• a hard-cover paperback book is provided which can be manufactured at a high production speed by using the glue-binding technique.
• the soft inner cover is fastened to the book block before fastening the hard outer cover
• the outer face of the spine of the inner cover as glueing face for the hard outer cover.
• a sufficiently large adhering face is obtained for the hard outer cover so that the hard outer cover is fastened reliably to the inner cover and, by its intermediate, to the entire book block even at high production rates.
• the soft inner cover is fastened to the book block only at its front and back cover but not at its spine, in the finished book the spine of the hard cover is loose from the book block in spite of the fact that the spine of the hard cover is fastened to the spine of the soft cover.
• Another subject of the present invention is a procedure for the manufacture of a book in accordance with the invention, and this procedure is characterized in what is stated in claim 5.
• a hard-cover book can be manufactured simply and rapidly in a glue-binding machine, which has been so far suitable only for the manufacture of soft-cover books.
• FIGS. 1A to 1F schematically illustrate various steps of manufacture of a book in accordance with a preferred embodiment of the invention
• Figure 2 shows a finished book as viewed from the end and as spread open
• Figures 3A to 3F illustrate the steps of manufacture of a book in accordance with a second embodiment of the invention.
• Figure 4 shows a finished book as viewed from the end and as spread open.
• FIG. 1A a number of separate sheets or leaves 1 are assembled together to make a bundle (Fig. 1A) , of which the spine edge is opened by cutting (Fig. 1B) so that a block or book block 2 consisting of bundled leaves is obtained, the spine 2a of the said block being plane.
• a cold glue layer 3 is spread onto the spine of the book block, as well as narrow glue stripes 4 onto the first page la and last page lb of the book block alongside the spine edges of the leaves.
• a crepe strip 5 is pressed against the glue layer and the glue stripes (Fig. 1A) , of which the spine edge is opened by cutting (Fig. 1B) so that a block or book block 2 consisting of bundled leaves is obtained, the spine 2a of the said block being plane.
• a cold glue layer 3 is spread onto the spine of the book block, as well as narrow glue stripes 4 onto the first page la and last page lb of the book block alongside the spine edges of the leaves.
• a crepe strip 5 is pressed against the glue layer and
• crepe strip functioning as a support layer and binding the leaves firmly together at the spine.
• hot glue stripes 6 are spread onto both edge portions of the crepe strip, said edge portions being fastened by glueing onto the first and last leaf of the book block.
• a soft inner cover 7 is placed onto the book block and, by means of its front and back portions 7a, 7b, pressed into contact with the glue stripes (Fig. 1D).
• the unit formed in this way is cut at its upper, lower and front edges to the desired size (Fig. 1E) .
• the spine portion 7c of the inner cover is loose from the crepe strip 5.
• a hot glue layer 8 is spread onto the outer face of the spine of the inner cover and cold glue layers 10 are spread onto the inner faces of the front and back covers 9a, 9b of a prefabricated hard outer cover 9.
• the hard outer cover is placed onto the book block half provided with covers, and the hard outer cover is, by means of its glue layers, pressed into contact with the inner cover (1F).
• a hard-cover paperback book is obtained wherein the cover extends, in the same way as in a hard-cover book, slightly beyond the book block at its upper, lower and front edges.
• an auxiliary cover is first fixed to the book block, said auxiliary cover forming the inside portion of the finished cover and extending around the front and back sides and the spine of the book block, and that it is only hereinafter that the outer cover forming the hard cover proper is fixed. Owing td this, the entire outer face of the inner cover, including the spine, is available for glueing the hard outer cover and, nevertheless, the spine 9c of the finished cover can be made to remain loose from the book block. In this way the hard outer cover can be made to adhere so precisely and reliably that the book block can be provided with hard cover in a glue-binding machine.
• the front and back sides of the inner coyer which was in advance fastened to the book block, said front and back sides being at the final stage glued onto the inner sides of the front and back covers of the hard cover, thereby function as portions covering the inner sides of the hard cover.
• the inner cover 7 is made of an integral soft sheet, but it is also possible to assemble the soft inner cover in advance out of separate components to make an integral piece which is then fastened to the book block by glueing, or to assemble the inner cover out of separate parts which are as individual working steps fastened to the book block by glueing to make a ready inner cover.
• the inner cover 17 is composed of three separate parts, viz. a front-side folded foreleaf 18, a back-side folded foreleaf 19, and a spine strip 20.
• the spine strip is. fastened by means of hot glue stripes 21 at its edges to the outer face of both foreleaves, as is shown in Fig. 3D.
• the soft inner cover assembled in this way in advance is treated exactly in the same way as is shown in Figures 1D, 1E and 1F.
• the foreleaves forming the inner cover may be utilized as coloured leaves, map leaves or equivalent, and integral foreleaves additionally form a tidier joint between the cover and the book block.
