Definitions

  • This invention relates to a method of binding books at an industrial production level and books produced thereby.
  • a well known and widely ,,!cd method of binding books industrially comprises the following sequential steps: a spine bowing step wherein the spine of a package of stacked pamphlets or loose sheets intended for forming a book is bowed or rounded under a high pressure, e.g. by passing it under pressure rollers; an adhesive and gauze or cloth application step, following said bowing step; a step wherein the so-called headband is applied to the spine over the adhesive coating, usually along with the paper backing of said gauze; and a step wherein the headband is caused to closely adhere to the spine by means of a pressure roller.
  • the book is provided with a rigid or semirigid cover which is made to adhere to the first and last pages or sheets of the stacked pamphlets, with the exception of the spine region thereof.
  • That known method is a universally employed one, but is rather critical to carry out in practice because those operations which affect the spine of the book imply work on an arcuate surface, both for the application of the adhesive and of the headband, as well as the adhesion of the latter.
  • that method not only requires the availability of a machine for bowing the book spine, but also one for working on the bowed spine and operative to drive and move along an arcuate path the adhesive-applying rollers and cylindrical pressure rollers.
  • cylindrical rollers being made to roll over the book spine, in a transverse direction thereto, grooved rollers are employed having an arched groove, which are caused to run longitudinally over the book spine.
  • Such grooved rollers can be driven without difficulty, since their axes are only required to move linearly, but their grooves must have width and depth dimensions which are exactly adjusted to fit the size of the book being processed.
  • GB - A-441 294 teaches to secure a lining provided with creases or pleats on the spine of a book by gluing it thereon while the spine is flat and to effect the rounding of the spine afterwards.
  • US-A-3 840 254 concerned with the problem of plastic memory in the adhesives, which upon rounding of the spine has the tendency to flatten the spine generating thereby local stresses.
  • the patent teaches to heat the spine after the rounding thereof to relieve the shape distorting stresses in the adhesive.
  • FR-A-934 655 teaches to effect the rounding of the spine on which previously a lining has been glued, before complete drying of the glue occurred.
  • the task of this invention is to remove the above drawback and render the use of headbands not only of decorative but also of mechanical nature.
  • the numeral 1 designates a pack or package of pamphlets intended for forming a book.
  • the package 1 has a flat spine 2.
  • To the spine 2 are applied those elements which usually bind or hold together the pamphlets or sheets which make up the package
  • a cover is made to adhere to the first and last pages of the package 1, said cover being of any desired type, e.g. a rigid or "hard” type with weakening or fold lines pre-formed adjacently the spine 2 and with a middle portion set away from the spine 2.
  • an adhesive is first applied by means of any suitable instrument.
  • two flat headbands 3 are positioned onto the flat spine 2 of the pamphlet package 1, with the optional interposition of a flat gauze 4 and an additional adhesive coating over the gauze 4.
  • the headbands 3 are then joined to a paper strip 5 which interconnects them together and overlies the optional gauze 4.
  • the headbands 3 and strip 5 have longitudinal edges 3a and 3b which protrude, cantilever-fashion, beyond the thickness of the package 1.
  • the extent of this protrusion of the edges 3a and 3b beyond the package 1 will be commensurate to the final dimensions of the spine after it has been bowed.
  • the spine 1 is conventionally bowed, in a manner known per se, by exerting a high pressure on the flat spine and the elements previously engaged therewith.
  • the selected adhesive is of the hot-melt type, simultaneously with the bowing of the spine, heat may be conventionally delivered to the adhesive such as to ensure that the selected condition of the adhesive allows full adhesion of the headbands 3, and of the gauze 4 if any, to the package bowed spine ( Figure 4).
  • the invention achieves its objects.
  • a relative sliding movement takes place between the spines of the individual pamphlets forming the package 1 and the headbands 3, to result in a headband drawing and stretching effect prior to their setting in position.
  • the headband 3 advantageously serves a mechanical retentive function as well as an aesthetical one.
  • the contact pressure applied to the headbands against the spine, as exerted during the spine bowing step, is, owing to the high pressure levels involved, adequate to ensure a permanent bond of the headbands with all the other elements and the pamphlets.
  • simple flat biasing surfaces may be employed.
  • the application of the aforementioned elements to a flat spine may be carried out at a low pressure and without inducing distortion, since the contacting is effected concurrently with the spine bowing.
  • the latter step may be carried out in a technically similar manner to conventional techniques.
  • the usual bookbinding method has been considerably simplified, by virtue of the adhesive, headbands and paper strip being, with this invention, applied to a flat spine, by means of simple standard devices, without involving any downtime for equipment adaptation.
  • the resulting bound book is better than conventionally bound ones, thanks to the perfect and stronger adhesion of the headbands to the book spine.
