Definitions

  • the present invention relates to a folder for use in thermal binding.
  • the present invention relates to such a folder formed from a flexible resilient plastics sheet material.
  • Thermal binding of a stack of papers into a folder is a convenient method for an end user to produce bespoke books or pamphlets.
  • Thermal binding folders are made of paper or light card and have a spine containing a strip of hot melt adhesive, see e.g. WO-A-95/06566.
  • Such folders tend not to be very durable or have a long life expectancy, since due to their fibrous nature, they can be easily torn or creased and separation of the bound papers from the folder can occur due to delamination of paper or card from which the folder is formed.
  • thermal binding cover which is durable, (ie. provides a bound folder which is resistive to tearing) and which is also capable of securely retaining the stack of bound papers for a long period of time.
  • a folder for thermal binding having a channel shaped spine containing hot melt adhesive, the spine being formed from a resilient plastics sheet material.
  • a folder including a spine to which front and rear cover sheets are connected, the spine, front and rear cover sheets being integrally formed from a resilient sheet plastics material, the spine being formed to define a channel having a bottom wall and opposed side walls, the front and rear covers being connected by respective fold-lines to upper edges of the side walls of the channel to define hinge connections, a hot melt adhesive located within the channel, the hot melt adhesive extending along the bottom wall and preferably at least partially along the side walls, said fold-lines being formed to substantially remove the inherent resilient bias of the sheet material about said hinge connections.
  • the channel is formed by folding the sheet material, the plastics material being adapted, for example by heat treatment, to retain the channel shape.
  • the hot melt adhesive is fused with the plastics material of the spine so as to provide a strong bond between the hot melt adhesive and said plastics material.
  • the hot melt adhesive is applied to the spine at a temperature in excess of the softening temperature of the hot melt adhesive.
  • the hot melt adhesive has a softening temperature of about 140°C and is applied to the spine at a temperature of about 170°C.
  • thermo binding folder the method including the steps of:
  • a method of producing a bound book having a folder as defined above containing a plurality of pages including producing the folder as defined above, placing a stack of sheets into the folder with one edge of the stack located within the channel defined by the spine, applying heat to the spine at a second elevated temperature in order to cause softening of the hot melt adhesive, the hot melt adhesive at said second elevated temperature being capable of adhering to the individual sheets comprising said stack, controlling application of heat at said second elevated temperature so as to avoid changing said modified memory position.
  • said first elevated temperature is chosen so as to cause surface fusing between the hot melt adhesive and said plastics material forming the spine and said second elevated temperature is chosen to be less than said first elevated temperature such that softening of the hot melt adhesive at said second elevated temperature does not affect the fused connection between the hot melt adhesive and the spine.
  • a folder 10 formed from a sheet of resilient plastics material so as to include a spine 12, a front cover sheet 14 and a rear cover sheet 16.
  • the spine 12 is formed to define a channel 18 having a bottom wall 19 and opposed side walls 20, 21.
  • the spine 12 is preferably formed by folds 22, 23, 24 and 25 to define the channel 18. Folds 22 and 25 also define hinge connections by which rear and front cover sheets 16, 14 are connected to upper edges of side walls 20, 21 respectively.
  • the spine 12 is formed by folding the sheet material about folds 23 and 24 and during the folding process changing the memory of the plastics so as to retain the channel shape.
  • the thus formed channel is subsequently filled with hot melt adhesive 28.
  • the adhesive 28 fills the channel so as to cover the bottom wall 19 and extend at least partially upwardly opposed side walls 20, 21. In this way, after the hot melt adhesive has set, it assists in restraining the sheet material from bending about folds 23, 24 and assists the spine to maintain its channel shape and helps render the spine relatively rigid.
  • the folds 24, 25 and 22, 23 are spaced apart by a relatively short distance to define the height of the opposed side walls 20, 21.
  • the height of side walls 20, 21 is preferably between 1 to 10 mm, more preferably is about 5 mm and helps resist deformation of the channel sides by bending in use.
  • the height of the opposed sides is preferably the same irrespective of the width of the channel bottom 19.
  • the hot melt adhesive is preferably applied at a first elevated temperature which is sufficiently high to cause at least partial fusing between the contacting surfaces of the spine and the hot melt adhesive.
  • Application of the hot melt adhesive at the first elevated temperature is controlled such that the memory of the plastics material is not changed.
  • the spine is cooled rapidly immediately after application of the hot melt adhesive. This restricts fusing to the surface region of the plastics material forming the spine and prevents the temperature throughout the plastics material rising to a sufficient level to cause softening and changing of memory of the material.
  • the folds 23,24 are formed such that the outer face 19 a of the bottom wall 19 is substantially flat, ie. the folds 23,24 do not project outwardly beyond the face 19 a .
  • the outer face 19 a is able to sit in face to face contact with the hot plate of the thermal binding machine and thereby ensure rapid heat transfer from the hot plate to the hot melt adhesive in the channel.
  • Folds 22, 25 are formed so as to substantially remove the inherent resilient bias of the sheet material. This enables the respective rear and front covers to be hingedly moved about their respective folds without unduly distorting the relatively rigid spine. Accordingly the spine maintains its shape and is not adversely distorted by movement of either the front or rear cover sheet about their respective folds prior to binding.
  • the sheet plastics material is preferably a thermal plastics capable of retaining a memory position such as polypropylene, or polyethylene, other suitable plastics materials are polystyrene, a polyester or rigid polyvinylchloride. Co-polymers of the above plastics materials may be used.
  • the thickness of the sheet material preferably ranges from about 300 ⁇ up to 2000 ⁇ .
  • the channel of the spine may be formed by heat deformation techniques in which case folds 23, 24 would be omitted.
  • the hot melt adhesive used in connection with polypropylene is based upon an ethylene vinyl acetate co-polymer.
  • the molten hot melt adhesive is preferably applied to the spine at a temperature of about 170°C.
  • Binding of sheets into a folder 10 to form a bound book 30 having pages 31 is achieved by taking a stack of sheets and locating the stack within the folder 10 such that an edge of the stack is located within the channel 12a.
  • the filled folder 10 is then placed in a thermal binding machine (not shown) and the hot melt adhesive 28 is heated to a second elevated temperature (ie. a binding temperature) at which it softens and penetrates the sheets so as to bond thereto.
  • the second elevated temperature is selected to be lower than the first elevated temperature so as not to affect the fused bond between the hot melt adhesive and the spine. Accordingly a strong bond is maintained between the hot melt adhesive and the spine.
  • the second elevated temperature is controlled so as not to affect the memory of the plastics material forming the channel 18.
  • the plastics material forming the spine 12 maintains its memory for retaining the shape of the channel 18.
  • the bound spine 12 thereby has opposed side walls 20, 21 which are restrained from moving about folds 23,24 and so is relatively rigid, ie. the side walls of the spine tend to maintain their positions relative to the bottom wall 19 irrespective of the amount by which the cover sheets 14,16 or pages 31 are moved in during opening of the book and there is only a slight bending of the spine primarily within the region of the bottom wall 19.
  • plastics material for the spine its sheet thickness and the hot melt adhesive are preferably chosen to permit said slight bending of the bottom wall 19 as this enhances the durability of the bound book. Absolute rigidity of the bottom wall of the spine is not preferred.
  • the marginal portions of the page sheets are protected from excessive folding and so fibrous sheets such as paper, or even coated paper, maintain their integrity in the region of the spine and so can be successfully retained.
  • the second elevated temperature is preferably about 140°C.
  • thermal binding folder of the present invention it is possible to bind sheet materials to form a permanently bound book.
  • Such books could be used for example as registers for recordal of permanent information.
  • such books have only been produced by traditional stitch binding techniques.
  • the hot melt adhesive is elevated to its binding temperature by heat conduction from a hot plate thermal binding machine.
  • the hot melt adhesive may contain metal particles and be exposed to an electrical field so as to be heated by induction.
  • a hot melt adhesive responsive to ultraviolet radiation may be used.
