Definitions

  • the present invention relates to a material specially designed for production of a substantially rectangular book cover suitable for a certain range of book formats, knowing that in the present text, the term "book cover” is general in scope, including including notebook protectors or other similar applications and that even the term rectangular is not restrictive to the geometric shape of the rectangle but includes any related format, in particular square, suitable for cover three faces with a three-dimensional element of the book type.
  • the protection of a book is carried out in covering the outside faces of the book cover, namely the two flat and back, of a sufficiently strong covering material, for example kraft paper or plastic.
  • a sufficiently strong covering material for example kraft paper or plastic.
  • the user takes a sheet of said material, having a more dimension important as the format of the book, lay the book flat and open so central on the sheet and by cutting and folding operations form flaps coming towards the interior face of the dishes of the books.
  • These flaps are preferably fixed between them by an adhesive tape or possibly with the inside of the cover plate, so that the book cover stays put.
  • the precuts (30,31) there are five precuts (30,31), namely a central precut (30) and four lateral precuts (31) arranged symmetrically with respect to the central precut (30); said five pre-cuts delimit six stripes (A, A, B, B, C, C), divided on both sides and on the other from the central precut (30).
  • the user begins by cutting in the material for book cover to delimit the flaps (E, F, G) intended to come on the internal faces of the dishes (12,13) of the book; more precisely he realizes on both sides of the central precut (30) four V-shaped notches delimiting two lower and upper portions (J, L), each extending the back of the book.
  • the goal set by the applicant is to offer a material book cover which overcomes the aforementioned drawbacks.
  • the sheet protective has a single precut delimiting a band for the front cover and a single strip for back cover and the second dish of the book.
  • the sheet protective has two precuts defining a band for the cover of a first cover, a strip for the back cover and a strip for the cover of the second dish.
  • the concept of covering a book dish includes not only the covering of the outside face of said dish but also the formation flaps on the internal face of said dish.
  • the pressure-sensitive adhesive is an adhesive repositionable or removable, i.e. an adhesive that can be removed without damage to the cover of the book after a limited time (repositionable) or unlimited (removable).
  • each strip formed in the protective sheet depends on the configuration of the book, for a range of determined formats.
  • the material of the invention has a total width L (which corresponds to the sum of the widths of the two plates, of the back of the book and of two flaps) given.
  • L which corresponds to the sum of the widths of the two plates, of the back of the book and of two flaps
  • I 1 and I 2 we preferably have I 1 between 0.6 and 0.55L and I 2 between 0.4 and 0.45 L.
  • the central strip has a width d which is between 0.05 and 0.3 L, the other two lateral strips having the same width.
  • the central strip of the protective sheet has visible transverse and / or oblique marking lines.
  • the lines of transverse markings are intended to facilitate centered placement of the back of the book, symmetrically with respect to the material.
  • the lines of oblique marking they are intended to facilitate the layout of the cutouts for form the flaps. These can be pre-printed lines on the right side of the protective sheet or possibly on the reverse side if the sheet is transparent or translucent.
  • the material 1 is intended for cover book 2, specifically to be placed on the outside of the cover 3 of the book, which consists of the back 4 and the two dishes 5, 5 '.
  • This material 1 is constituted by the assembly of two sheets, namely a first sheet 6 called the covering sheet whose reverse side 6 a is coated with an adhesive 7 sensitive to pressure and a second sheet 8 called protective which is in a non-stick material or whose reverse side is coated with a non-stick material.
  • a first sheet 6 called the covering sheet whose reverse side 6 a is coated with an adhesive 7 sensitive to pressure
  • a second sheet 8 called protective which is in a non-stick material or whose reverse side is coated with a non-stick material.
  • the non-stick material of the protective sheet 8 is applied against the pressure-sensitive adhesive 7 of the cover sheet 6.
  • the two sheets 6, 8 have the same dimension and are rectangular, of width L and height h, corresponding to a format or a range of book formats 2.
  • the protective sheet 8 has two cutouts 9, parallel between them and parallel to the two short sides 10 of the rectangle, said cutouts 9 being arranged symmetrically on either side of the axis DD 'of the material 1, being spaced from one another by a distance d .
  • the ratio between this distance d and the width L of the material 1 is of the order of 0.05 to 0.3.
  • the two cutouts 9 delimit in the protective sheet 8 three bands, namely a central band 12 and two lateral bands 13,13 '.
  • the two cutouts 9 are preferably total, that is to say that they extend over the entire height h of the protective sheet 8 between the two 11 long sides of the rectangle. They can however be partial provided that they allow easy detachment from the central strip 12 relative to the two lateral strips 13,13 ', and its removal from the sheet cover 6 in the assembly.
  • the implementation of the material 1 for book cover comprises the following steps, which are illustrated in Figures 1 to 10.
  • the user places the material 1 on a flat support, the right side of the protective sheet 8 being apparent ( Figure 1). He applies book 2 to protective sheet 8, plus i precisely it applies the back 4 of book 2 in a manner substantially centered on the central strip 12 of the protective sheet 8. He is helped in this by the presence of the two cutouts 9, the edges formed between the back 4 and the dishes 5.5 'of cover 3 of book 2 to be parallel to the two cutouts 9 and at equal distances from them.
  • the centering of book 2 must also be do with respect to the long sides 11 of the material 1.
  • the user draws location lines 14 on the protective sheet 8, to mark the location of the edges upper 15 and lower back 4 of the book and also to mark the oblique cut lines to form the flaps 16.
  • the user cuts the two sheets 6, 8 assembled along the reference lines 14 which he has just traced (FIG. 3) and he removes the excess portions 16 which, in the example illustrated, have a form of isosceles trapezoid.
  • the user detaches the central strip 12 from the protective sheet 8, detachment which can occur thanks to the presence of the two cutouts 9 (FIG. 4). It thus releases a central zone 17 from the reverse side 6a of the covering sheet 6, coated with the pressure-sensitive adhesive 7. It picks up the book 2 and reposition the back 4 of the latter in the same position as it had adopted during the drawing of the marking lines 14 (FIG. 5). It detaches from the assembly a first lateral strip 13 so as to release the reverse side 6 a of the covering sheet on which this lateral strip 13 was applied (FIG. 6). It rotates the book 4 so that the flat 5, facing, comes to apply on said reverse side 6a thus released.
  • the pressure-sensitive adhesive therefore ensures the bonding of the covering sheet 6 over the entire surface of the back 4, over the entire outer surface of the first dish 5 and on the interior surface part of this first dish 5 corresponding to the three flaps. 16. It then suffices for him to close the book 4 and carry out the operations illustrated in FIG. 6 to FIG. 9 to obtain the complete positioning of the book cover using the material 1 of the invention. Preferably it is preferable to avoid the immediate handling of the book thus covered and advantageously to place a load on the book, laid flat on one of the dishes (figure 10) so as to consolidate the bonding of the book cover on the delivered.
  • the protective sheet 8 has lines of marking pre-printed on its face side that is to say that which is directly visible to the user.
  • FIG. 11 an exemplary embodiment of such has been illustrated. marking lines on the central strip 12.
  • pre-printed marking lines 21 are arranged transversely, parallel to the two long sides 11 and symmetrically with respect to the axis median EE 'perpendicular to the axis DD'.
  • axis median EE ' perpendicular to the axis DD'.
  • Each game can in particular be of a different printing color. So it suffices to the user when positioning the back 4 of the book to verify that both sides upper 15 and lower back are arranged at or near immediate and at the same distance from two lines 21 of the same color.
  • oblique marking lines 22 arranged on the strip central 12 their only ambition is to give direction general to help the user, general direction corresponding to an angle preferably 45 °, for oblique cutting 14.
  • the pressure sensitive adhesive which is used may be an adhesive repositionable, i.e. an adhesive that can be removed from the backing against which it is applied, without deterioration of said support, after a time limited, for example a few minutes. It can be a removable adhesive, which can be removed after a much longer time, from several years.
  • the desired result is obtained, that is to say the removal of the cover sheet without altering the book and without depositing glue on the book by the implementation on the reverse side of said sheet of covering of a first lower layer of an adhesion primer and a second upper layer of a removable adhesive, having a force of coat (International Standard PSTC 1) preferably less than 5N / 25mm (5N / inch).
  • the cover sheet is made of unstretched cast polypropylene (called commonly "cast") and its reverse side has undergone a Corona treatment or by flame to obtain a surface tension greater than 44 dynes / cm (44 mN / m).
  • the first layer of the adhesion primer is based on styrene-butadiene or acrylic, thickness between 2 and 5 micrometers.
  • the second layer of adhesive is an acrylic glue, thickness between 8 and 15 micrometers. Thanks to the primary adhesion, the adhesive remains stuck on the cover sheet during removal of the book cover. This is the value of the peel strength of the glue of the second layer which gives the removable character, this value being however dependent on the surface on which the sheet of adhesive is stuck recovery; generally less than 5N / inch is acceptable for books with a rigid cardboard cover and an interior of kraft paper cover. In some cases, including soft covers, the desirable value of peel strength of the adhesive of the second layer may be even lower.
  • the size of the material 1 is chosen according to the format of the delivered.
  • the total width L was 500mm
  • the height h was 350mm
  • the width d of the central strip was 60mm
  • that of the two lateral strips was 220mm.
  • the second exemplary embodiment which is illustrated in FIG. 12 differs from the first only by the fact that the protective sheet 23 of the material 24 comprises only a single cutout 25 which delimits, in said protective sheet 23, two strips of different widths , the first 26 of width I 1 for the cover of a first dish of the book and the second strip 27 of width I 2 for the cover of the back and of the second dish of the book.
  • Cross and oblique reference lines can possibly be provided on the second strip 27, near the cutout 25 that is to say substantially at the location where the central strip in the first exemplary embodiment.
  • the user discovers the second strip 27 either by raising said strip 27 from cutout 25 to leave visible an area of adhesive for the placement of the back either by simply removing the entire strip 27.
  • the adhesive used is not necessarily an adhesive sensitive to the pressure, it can also be a reactivatable adhesive, in particular hot.
  • the reverse side of the sheet protective either in a non-stick material.
  • the character detachable from the protective sheet relative to the cover sheet can be obtained by a corrugated or embossed surface of the sheet protective, in particular when the sheets used are of the type polyvinyl chloride.
