Definitions

  • the present invention relates to a cover and process for the binding of a plurality of loose pages together using just a stiff strip of a binding adhesive to attach the pages together along shingled edges of the pages.
  • the binding cover of the present invention is adapted to replace various binding systems for a plurality of pages up to about 25 pages.
  • Prior binding systems for a small number of pages comprised staples, loose-leaf binders, mechanical fasteners, i.e., paper clips, prongs and fasteners as sold by Acco International Inc., Chicago, Illinois 60630, paper fasteners and washers as sold by Swingline, Inc., Long Island City, N.Y. 11101, plastic rivets, pins, slide strip binders and other jackets with built-in prongs for retaining perforated sheets. Binding by the use of performed covers having a hot melt adhesive requiring a mechanism or tool for effecting the binding operation is not considered relevant.
  • the essential difference between the present invention and the prior art is that a cover corresponding to the present invention may be utilized to bind a plurality of sheets or papers together without the use of tools, fixtures, machines, electrical power, or lapsed time for heating or cooling the adhesive.
  • the shingling prior art states that only supple adhesive zones can be used to produce bound documents.
  • the cover of the current invention consists of a stiff backing divided into a front and back portion with a strip of pressure-sensitive adhesive along the dividing line and a release material is provided to protect the adhesive prior to the binding operation.
  • the plurality of pages bound together by this binding cover reduces required storage space, allows stacking and the lay-flat feature provides for easy copying, reading, handling and page butting.
  • the present invention is directed to a backing for binding sheets together, which backing is formed of cover card stock creased across by a central fold score line to form a front and back portion.
  • the cover portions have a length which is at least equal to the length of the paper to be bound plus some marginal dimension if desired, and a width corresponding to the width of the paper to be bound plus the width of the binding adhesive which is located on the back cover along one marginal longitudinal edge at the central fold score line and extending marginally across onto the front cover plus some marginal dimension if desired.
  • the band of binding adhesive is protected initially by a strip of a release material (such as a liner) which will allow for the easy exposure of the adhesive band as needed for binding.
  • a strip of a release material such as a liner
  • a backing for binding sheets together which backing includes a flap attached along the fold line of the backing or the backing is formed of a sheet of cover card stock which has a length which is at least equal to the length of the paper to be bound plus the width of the binding adhesive along one marginal longitudinal edge at which a fold line connects the back panel to a flap which has a length corresponding to that of the backing and a width which is equal to the width of the band of binding adhesive adjacent the fold line and a narrow band of pressure sensitive adhesive is coated along the free edge of the flap for attachment of any desired additional cover member.
  • the band of binding adhesive and the band of adhesive for attaching the cover are each protected initially by a strip of release liner material which will be easily removed from the adhesive liner material which will be easily removed from the adhesive to expose the adhesive for binding.
  • the binding adhesive is preferable an adhesive with good initial adhesion and preferably a value of at least 396.9 gms per 1.27 cm (fourteen (14) ounces per one-half inch) or greater as measured by the Pressure Sensitive Tape Council (PSTC) "Quick Stick" test No. 5.
  • PSTC Pressure Sensitive Tape Council
  • the backing of the present invention is illustrated and comprises a sheet 10 of cover stock which may be a paper composition having a caliper of about 0.22 mm (0.009 inch) and a basis weight of 36.3 kg (80 pounds) per ream (50.8 cm x 66.04 cm) (ream size 20 inches x 26 inches), which sheet has been formed with a flexible fold line 11 to form one longitudinal edge of the back portion 12 and one longitudinal edge of the front portion 13 and defining the line joining said portions of substantially the same dimensions.
  • cover stock may be a paper composition having a caliper of about 0.22 mm (0.009 inch) and a basis weight of 36.3 kg (80 pounds) per ream (50.8 cm x 66.04 cm) (ream size 20 inches x 26 inches), which sheet has been formed with a flexible fold line 11 to form one longitudinal edge of the back portion 12 and one longitudinal edge of the front portion 13 and defining the line joining said portions of substantially the same dimensions.
  • the sheet material along a zone adjacent the fold line 11 has a flexural rigidity of at least 2.26 x 10 ⁇ 4 newton-meter (0.002 inch-pounds) thus providing a backing which has a stiffness sufficient to allow easy handling during the binding process and gives the bound document security in use.
  • the central fold line must not be so stiff as not to allow easy closure of the cover, therefore, it should have a flexural rigidity of less than 3.4 x 10 ⁇ 3 newton-meter (0.03 inch-pounds), it may be preferred to keep the entire backing within these limits. Stiffness and flexural rigidity are determined by test No. 409 of the Useful Methods tests published by the Technical Association of the Pulp and Paper Industry (TAPPI).
  • a narrow band of pressure-sensitive adhesive 15 is coated over the zone along a longitudinal edge of the back portion 12 adjacent to the central fold score line 11.
  • the adhesive extends slightly across this fold line 11 and the adhesive 15 is covered by a protective release material such as a liner 16, a strip having a coating of silicone with a release value of between 10 and 25 grams per 2.54 cm.
  • the adhesive is a very tacky pressure-sensitive adhesive which is in contact with the shingled edges of the sheets to be bound therein. Stress can occur during the final stages of the binding process which will cause the shingled edges to move, therefore, the adhesive must have good quick stick qualities, to allow the pages to stay attached after the initial adhesive contact, with minimal pressure and dwell time.
  • a suitable adhesive for use with this binder is a normally tacky pressure-sensitive iso-octyl acrylate/acrylic acid copolymer in a 95.5:4.5 ratio.
  • This pressure-sensitive adhesive has good initial adhesion which can be measured by the "Quick Stick” test 5 of the PSTC (Pressure Sensitive Tape Council).
  • the dimensions of the back portion 12 and front portion 13 of the backing are dependent on the length of the paper to be bound and the length is at least equal to the length of the paper to be bound but may be provided with an additional marginal dimension of, for example, 0.6 cm (0.25 inch).
  • the width of the back portion corresponds to the width of the loose pages to be bound plus the width of the binding adhesive but may be provided with an additional marginal dimension of, for example, 0.6 cm (0.25 inch).
  • the front portion is illustrated as having a dimension equal to the dimensions of the back portion although the front portion could be narrower for a flap to which a transparent film or other cover stock could be joined to form the booklet cover.
  • the covers are preferably made for use in bindings containing a maximum of 25 sheets of paper 23.
  • the folded pages are then slid along the inside of the front cover portion to the central fold score line 11, as illustrated in Figure 4, and the back cover portion is then closed so that the binding adhesive is pressed into contact with the shingled edges of the sheets. After the adhesive has been pressed into the shingled pages the folded sheets are released and allowed to lay straight.
  • the cover portion 13 is then opened to the first page and the shingled pages 23 are again pressed into the adhesive, taking care to run a finger along the page edges, as illustrated in Figure 5.
  • a document can be tested to determine whether the adhesive used provided an adequate binding for the sheets. the following test was established to assess the peel strength of a page to the binding adhesive when removed at a 45° angle.
  • the document or booklet 30 illustrated in Figure 6 is first cut to provide a section 31 of the booklet 7.6 to 10 cm (3 to 4 inches) wide at the bound edge and 15.24 cm (6 inches) long.
  • This cut section is then placed on a fixture 35 illustrated in Figure 7, which fixture comprises a horizontally disposed portion 36 and an angled portion 37 disposed at 45° to the horizontally disposed portion 36.
  • the document sample 31 is opened to expose the third sheet 39 and the remaining pages and the sheet 39 are then clamped along the upper marginal edge 40 of the angled portion by a clamp 41.
  • the horizontal portion is then placed in the lower jaw 50 of an Instron tensile tester, made by Instron Corp.
  • An acceptable average value for this peel test of a booklet would be at least 40 grams with at least 70 grams and above being preferred.
  • Another test method is a 180° shear test to establish whether the adhesive has sufficient shear strength to a document page.
  • This test is done on an Instron tensile tester, see Figure 9, after preparation of a booklet sample as illustrated in Figure 6 wherein a 2.54 cm (one inch) wide sample 60 is cut from the finished booklet. Placing the top front page of the sample toward the operator, the operator positions the third sheet 61 from the sample 60 in the top jaw 51 of the Instron tensile tester and all of the remaining pages in the bottom jaw 50. Then calibrate the test equipment with a crosshead speed of 12.7 cm (5 inches) per minute, chart speed at 10 inches per minute, gauge length at 12.7 cm (5 inches) and use the Gram Cell at 1000 grams full scale.
  • the strip of adhesive can be formed on the backing by coating a series of strips of adhesive to the desired width along the fold line, by applying a continuous strip of adhesive, or by applying an adhesive which has been previously coated onto a release liner and is then applied as a tape to the cover.
  • spots, strips, or a continuous strip over an area adjacent the fold line, preferably on both sides thereof, are considered to constitute a band of adhesive.
  • the cover portion 13 is a flap with a band of adhesive 26 and a removable liner 27 positioned along the edge opposite the fold line 11.
  • the binding adhesive 15 includes an additional or extended portion 17 which may extend across the fold line 11 onto the front cover portion 13 which extended adhesive has a width of about Pi ( ⁇ ) times the paper thickness.
  • a removable liner 16 is applied onto the adhesive 15 and may have a low adhesion coating on both sides to also contact the small band of additional adhesive 17.
  • the cover stock is a paper composition having a caliper of about 0.28 mm (0.011 inch), which sheet has been formed with the fold line 11 along one longitudinal edge to join the back portion 12 to a front flap 13 of the same longitudinal dimension but substantially narrower.
  • the cover stock is flexible and has a stiffness or flexural rigidity as determined by the Technical Association of the Pulp and Paper Industry (TAPPI) Useful Methods test 409 of between 6.78 x 10 ⁇ 4 and 5.65 x 10 ⁇ 5 newton-meter (6 x 10 ⁇ 3 and 5 x 10 ⁇ 5 inch pounds).
  • TAPPI Technical Association of the Pulp and Paper Industry
  • Such a material provides a backing which is flexible but yet has a stiffness to give a bound document sufficient rigidity to hold the pages and to be placed on a shelf.
  • the dimensions of the back portion 12 of the backing illustrated in Figure 10 has a length which is dependent on the length of the sheets or pages 20 to be bound and is at least equal to the length of the pages to be bound.
  • the width of the back portion 12 corresponds to the width of the loose pages 20 to be bound plus an extended width including the width of the band of binding adhesive 15 and the width of the flap 13 minus the width of the band of adhesive to bind the back page or ⁇ t, where t is the thickness of the back page.
  • the width of the binding adhesive is determined by the product of the maximum number of pages to be bound plus 1 times the paper or page thickness (t) times pi ( ⁇ ).
  • R min the minimum radius of the wrapped back portion 12 and pages before they strike the flap
  • the backing is preferably made for use in binding 10 to 25 sheets and includes a band of adhesive along the score line having a width equal to (t equals the sheet thickness, X° equals the minimum degree of shingling or 180°, and N equals the maximum number of pages to be bound).
  • the amount of shingling is limited by the curvature of the adhesive strip.
  • the fingers clamping the pages adjacent edge 28 are released and the wrapped backing is allowed to open.
  • a finger should then be run along the edges of the pages to press them more firmly against the adhesive 15.
  • the flap may then be raised and the release liner 27 removed from the adhesive band 26.
  • a cover 29 may then be placed upon the pages 20 and aligned as desired. The flap is then folded against the top surface of the cover 29 and the band of adhesive 26 will adhere the cover 29 in place on the flap 13.
  • a bound document can be tested to determine whether the adhesive used provided an adequate binding for the sheets in the same manner as described above.
