Definitions

  • the present invention relates to binding elements for holding a plurality of perforated sheets or the like, and methods of forming and assembling the same into a stack of perforated sheets. More specifically, the invention pertains to spiral type binding elements and their assembly and insertion into a stack of perforated sheets.
  • binding elements have been utilized to bind a stack of perforated sheets or the like.
  • Numerous types of binding elements include a spine, from which a plurality of fingers extends which may be assembled through perforations in a stack of sheets.
  • This spine may be linear, with or without a longitudinally extending hinge. Alternately, the spine may be formed by sequential bending of a wire, as with wire comb or hanger type binding elements.
  • binding elements which are of a wire comb or hanger-type design are disclosed, for example, in U.S. Patent 2,112,389 to Trussell and U.S. Patents 4,832,370 and 4,873,858 to Jones, while machines for assembling such binders are disclosed in U.S. Patent 4,031,585 to Adams, U.S. Patent 4,398,856 to Archer et al., U.S. Patent 4,525,117 to Jones, U.S. Patent 4,934,890 to Flatt, and U.S. Patent 5,370,489 to Bagroky.
  • Other binding devices are disclosed, for example, in the following references: U.S. Patents 2,089,881 and 2,363,848 to Emmer, U.S.
  • Patent 2,435,848 to Schade U.S. Patent 2,466,451 to Liebman, U.S. Patent 4,607,970 to Heusenkveld, U.S. Patent 4,904,103 to Im, U.S. Patent 5,028,159 to Amrich et al., U.S. Patent 4,369,013, Reexamination Certificate Bl 4,369,013 and Re. 28,202 to Andugaard et al.
  • Machines for assembling plastic comb or finger binding elements are disclosed in patents such as U.S. Patents 4,645,399 to Scharer, U.S. Patent 4,900,211 to Vercillo, U.S. Patent 5,090,859 to Nanos et al., and U.S.
  • An alternate type of binding element is a spiral binding element, which includes a plurality of spaced, continuous, consecutive loops, as shown, for example, in FIGS. 1 and 2. The end of the spiral binding element is spiraled into the consecutive perforations in the stack of sheets to advance the consecutive loops into the perforations. Because spiral binding elements have no longitudinally-extending, continuous spine, a spirally bound stack of sheets may be folded back on itself without any resulting separation in the sheets due'to the spine being sandwiched between the sheets. Spiral bindings provide a relatively permanent book structure in that no additional sheets may be readily added to the book.
  • Spiral binding elements are typically made of wire or a polymeric material having a round cross-section. While each of these types of spiral binding elements has its advantages, each likewise has its disadvantages.
  • Spiral binding elements made of round metallic wire are typically relatively flimsy, and may be easily damaged and deformed by the application of an outside force exerted on the consecutive loops of the element. This damage may occur prior to spiraling it into a stack of sheets, rendering it difficult or impossible to spiral into the perforations in a stack or sheets. Alternately, such damage can occur to the binding element in a bound book, resulting in difficulties in use of the book and damaging the appearance of the bound book. Further, this flimsiness itself can cause difficulties in accurately spiraling the element into consecutive perforations in a stack of sheets.
  • polymeric spiral binding elements are relatively durable in that the application of an outside force to the element will typically only elastically, as opposed to plastically, deforms a polymeric element.
  • Polymeric spiral binding elements may also be formed in various colors, providing the user with options regarding the physical appearance of the resulting book.
  • Polymeric coils are sometimes viewed as being inexpensive looking and not sufficiently attractive for formal / 3 presentations.
  • polymeric spiral binding elements can be unstable to environmental effects, such as excessive heat, which can cause the coils to relax and can result in a change in the pitch and/or diameter of the spiral binding element. As a result, it can be difficult or even impossible to spiral the binding element into a perforated stack of sheets.
  • Machines for spirally binding sheets of paper generally involve one of two processes. Either the machine advances a preformed spiral binding element into the stack of sheets or the spiral binding element is formed at the binding machine itself, and advanced into the perforations in the stack of sheets as the element is formed.
  • a device that has been used to guide the feed of a spiral binding element into engagement with prepunched holes in a stack of sheets is a coiling tool.
  • One such tool arrangement for forming a metal wire into a spiral binding element and immediately feeding the spiral binding element as it is formed is described in U.S. Patent No. 3,592,242 to Sickenger.
  • the coiling tool includes a mandrel that is surrounded by a slotted member. Metal wire enters the slotted member at one end of the tool in the form of a wire which, as it turns, feeds successively through the series of punched holes in the sheet stack.
  • polymeric spiral binding elements are typically extruded and then wrapped around a heated mandrel to cool.
  • a polymeric spiral binding element as it is spiraled into a stack of sheets is relatively expensive, and requires the use of a relatively large machine.
  • Such machines use a plurality of mandrels, typically on the order of five, around which heated filaments are consecutively wound, cooled, removed, and then spiraled into the stack of sheets.
  • polymeric spiral binding elements require cooling time, the process relatively slow. That being the case, polymeric spiral binding elements are generally extruded, and then cooled. The preformed coil length is then spiraled into the stack of sheets.
  • a machine that advances a preformed spiral binding element into a stack of sheets is disclosed in, for example, U.S. Patent No. 4,378,822 to Morris, which discloses the assembly of books on a commercial scale.
  • Morris discloses driving a spiral coil between a mandrel and a drive wheel, both of which are disposed along one edge of the stack of sheets to be bound.
  • the mandrel guides the coil only until the coil actually commences to spirally engage the punched holes of the sheets. Accordingly, a critical difficulty in this type of arrangement is reliably guiding the spiraling free end of the coil along the length of the papers and through the punched holes in the sheets, particularly in view of the fact that spiral binding elements are generally relatively flimsy.
  • guide members may be disposed along the length of the punched hole edge of the sheets to assist in directing the movement of the spiral wire as it spirally winds through the holes in the sheets.
  • U.S. Patent no. 5,785,479 to Battisti et al. which is assigned to the assignee of this application, is one attempt to provide a desktop spiral binding machine.
  • the disclosed device includes a movable cartridge for feeding the spiral coil.
  • U.S. Patent No. 5,934,340 to Anthony, III, et al. also assigned to the assignee of this application, similarly discloses a desktop binding machine. Each of these units feeds a preformed coil through a stack of sheets and crimps the coil ends to complete a single book at a time.
  • binding elements can consume relatively large volumes of space and, therefore, result in relatively high costs associated with the real estate in packaging a feed magazine into the automated machine, as well as such packaging, shipping, and storage of the binding elements themselves.
  • the invention comprises a spiral binding element wherein the wire has a cross-sectional area that is preferably substantially rectangular, but may be any cross- section that provides increased strength over traditional round cross- section spiral binding elements. Such a spiral binding element provides more strength and durability than traditional, round cross-section wire binding elements. Further, the wire may be formed of a polymer and/or metal.
  • the invention further comprises a spiral binding element wherein the consecutive loops of the element are disposed substantially adjacent.
  • the compact spiral binding element not only takes up considerably less space than expanded elements, it is highly resistant to entanglement with other such elements.
  • efficiencies are realized not only in formation, packaging, shipping, and storing pluralities of the elements, the elements readily lend themselves to automated and semi- automated binding processes.
  • the compressed structure has increased strength over similar, but expanded binding elements, regardless of the cross-section of wire used or the material used.
  • the consecutive loops of the binding element can be separated or expanded to obtain the desired pitch before the binding element is delivered to a binding machine, or they can be separated immediately before the binding process.
  • One such method and apparatus for separating the consecutive loops comprises passing a cam surface between the consecutive loops, or rotating the spiral binding element over a cam surface disposed between the consecutive loops.
  • the separated, consecutive loops of the spiral binding element may then be directly spiraled into the perforations in a stack of sheets.
  • the binding element itself may be a discrete length of binding element, or it may be a continuous length of binding element that is then cut to the desired length.
  • the spiral binding element may be formed from a quantity of wire using structure similar to spring formers as the binding element is spiraled into the stack of sheets. Such formers could control both the pitch and diameter of the loops of the spiral binding element.

  • FIGS. 10A-C are enlarged, fragmentary, plan view of alternate camming surfaces in the arrangement of FIG. 7.
  • FIGS. 1 and 2 a spiral binding element 20 constructed according to the teachings of the prior art.
  • the binding element 20 is formed of a wire having a round cross-section, and comprises a plurality of successive, loops 22 that are spaced to correspond to the spacing of the perforations of a stack of sheets to be bound (not shown, but known in the art).
  • the spiral binding element 20 of the prior art is typically made of metal wire, comprises metal wire, or is formed of a polymeric material, such as polyvinylchloride.
  • a binding element 32 is formed of a wire 30 having a substantially rectangular cross-section, as shown in FIGS. 3 and 4. It will be appreciated that, while a substantially rectangular cross-section is presently preferably preferred, any cross-section that provides increased strength over round may be utilized. While the cross-section of the wire 30 may be any appropriate dimensions, a currently preferred embodiment has dimensions with a ratio on the order of 1 to 3, thickness to width. A binding element 32 having such a substantially rectangular cross-section is significantly stronger than a binding element (such as is shown in FIGS. 1 and 2) having a round cross-section in general, and, particularly, having a diameter that is the same as, smaller than, or even larger than the thickness of the rectangular cross-section element.
  • a binding element 32 constructed in accordance with these teachings is more resistant to damage in formation, packaging and shipping, spiraling into a stack of sheets, and in an assembled book.
  • the binding element 30 is preferably formed of metal. Further, it may be formed of any appropriate color whether it comprises metal or a polymer.
  • a binding element 40 may be formed with the consecutive loops 42 disposed substantially adjacently, as shown, for example, in FIG. 5, providing a very compact binding element 40.
  • the ends of the binding element 40 are spread from the main compressed section to illustrate how the consecutive loops 42 may be separated for binding a stack of sheets.
  • the binding element 40 is extremely strong and resistant to damage due to outside forces placed on the loops 42. Because there is substantially no space between the consecutive loops 42, the binding elements 40 will typically not become entangled when grouped and stored as a plurality, simplifying the processing and minimizing the costs associated with fabrication, storage, packaging, and usage of the binding elements 40.
  • the space necessary for packaging, storing and shipping of a plurality of such binding elements 40 is greatly reduced.
  • This compact nature and resistance to tangling further facilitates automated binding processes inasmuch as the space for storage of a plurality of such binding elements at the binding machine is greatly reduced, and the binding elements 40 can typically feed by rolling into a desired position without tanglement.
  • the length of the compact binding element 40 is considerably shortened relative to the expanded binding element (see 32 in FIG. 4). As a result, the space required for the binding element 40 itself at the binding machine is minimized, allowing for a smaller footprint binding machine.
  • binding element 40 shown in FIG. 5 comprises a rectangular cross- section
  • this aspect of the invention is likewise applicable to binding elements 50 having a round cross- section, as shown, for example, in FIG. 6, or any other cross-section.
  • round cross-section binding elements 50 may not exhibit the strength of a rectangular or other shaped cross-section binding element 40 (FIG. 5)
  • some enhanced strength will be provided over a spaced consecutive loop design, as illustrated in FIGS. 3 and 4.
  • a compact binding element 50 having a round cross-section will exhibit enhanced resistance to tangling during fabrication, packaging, shipping, storage, and usage. Similarly, this compact arrangement may be utilized with both metal and polymeric binding elements.
  • the consecutive loops 42, 52 of such compact binding elements 40, 50 may be separated either prior to assembly into a stack of sheets (to form longer lengths of the structures shown in FIGS. 3-4 and 1-2, respectively) or at the binding machine itself, just prior to spiraling the binding element 40, 50 into a stack of sheets.
  • a cam surface 60 is provided, as shown in FIG. 7, for example, and heat may or may not be applied during the expanding process. The cam surface 60 is disposed between consecutive loops 42, 52 of the binding element 40, 50 and causes deformation of the loops 42, 52 to space them apart.
  • consecutive loops 42, 52 While preferably the deformation is of a plastic nature such that consecutive loops 42, 52 permanently assume the spaced relation, it is possible that consecutive loops 42, 52 are only elastically deformed such that they are spaced only long enough to spiral the binding element into the stack of sheets. Clearly, such primarily elastic deformation would only be advisable in a binding element that is not particularly strong when spaced, such as the round cross-section binding elements of FIGS. 1-2.
  • one or the other of the binding element 40 or the cam surface rotate relative to the other such that the cam surface 60 passes along the length of the binding element 40, 50.
  • a simple handheld tool with a separating cam surface may be hand rotated about the compact binding element 40, 50, or the consecutive loops 42, 52 of the compact binding element 40, 50 may be hand rotated past such a simple cam surface.
  • the binding element 40 is rotated about it longitudinal axis as it progresses along the cam surface 60.
  • a drive roller 62 is provided, disposed adjacent the compact binding element 40 as it proceeds through support surfaces 64.
  • drive roller 62 As the drive roller 62 rotates, it advances the binding element 40 along the cam surface 60 to cause the consecutive loops 42 to separate one from the other. While a drive roller 62 is provided in the illustrated embodiment, an alternate arrangement may be provided for yielding forward motion of the binding element, and such drive arrangement may be disposed at any appropriate location.
  • the consecutive loops 42, 52 of the compact binding element 40, 50 may thus be separated and the resulting binding element spiraled directly into the perforations in a stack of sheets, allowing for relatively compact automated binding apparatus.
  • discrete lengths of compact binding elements 40, 50 may be so provided or a continuous length of compact binding element(s) may be provided which is subsequently cut to the desired length prior to consecutive coil separation, cut to the desired length at the time of separating the consecutive coils, or cut to length as the binding element is advanced through the perforations in a stack of sheets after consecutive coil separation.
  • a support structure 66 may likewise be provided as the separated consecutive loops exit the vicinity of the cam surface 60 and drive roller 62.
  • the cam surface 60 may similarly be disposed about the perimeter of a rotating or driven roller 68, as may be seen in FIGS. 8 and 9.
  • the cam surface 60 may merely be a stationary surface past which the binding element 40 progresses.
  • one or more of the cam surface 60, the drive surface of the drive roller 62 and/or structure holding the binding element 40, 50 may be moveably mounted relative to one another. As may be seen in FIG. 9, both the cam surface 60 and the drive roller 62 are mounted so that they may slide toward or away from the path of the binding element 40, 50. Alternately or additionally, varied cross-sectional cam surfaces may be provided in order to obtain the desired pitch. As may be seen in FIGS. 10A- 10C, progressively narrower cam surfaces 60a, 60b, 60c result in a steeper pitch, or closer consecutive loops 40a, 40b, 40c. This modification of the width of the cam surface may result from moving an angled cam surface closer or further away from the binding element 40, 50, or it may be accomplished by moving a different cam surface into communication with the binding element 40, 50, as shown in FIGS. 10A-10C.
  • the spiral binding element 20, 32 itself may be formed from a continuous length of wire at the binding machine by one or more appropriate cam surfaces and spiraled immediately into the perforations in a stack of sheets.
  • tools similar to custom spring formers may be utilized in the formation of the binding element 20, 32.
  • custom spring formers are disclosed in the website of BHS-Torin (www.bhs-torm.com/sprin machines/spring coilers.htm), which is hereby incorporated by reference.
  • tools or camming surfaces controlling only pitch and diameter would be required, greatly simplifying the formation apparatus over such custom spring formers.
  • the invention provides for spiral binding elements having a rectangular cross-section or a cross-section other than round, compact spiral binding elements having substantially no separation between consecutive loops of the element, arrangements and methods for separating consecutive loops of a compact binding element, and an arrangement for forming a spiral binding element at a binding machine. While this invention has been described with an emphasis upon preferred embodiments, variations of the preferred embodiments can be used, and it is intended that the invention can be practiced otherwise than as specifically described herein. Accordingly, this invention includes all modifications encompassed within the spirit and scope of the invention as defined by the following claims.
