Definitions

  • a system for producing articles such as cushions and mattresses wherein a plurality of coil springs are arranged with their vertical axes in substantially parallel relationship with a panel of material on at least one side overlying the coil ends.
  • the panels are provided with an adhesive on one surface, and the panels are continuously fed to a coil supply station. Rows of coils are provided at this station for engagement with the panel whereby the coils can be secured to the panel.
  • This invention relates to the production of cushions and mattresses.
  • the invention is concerned with mattresses primarily used for beds and comprising so-called innerspring mattresses.
  • the invention is also related to the production of loose cushions for furniture and the like, and is applicable to fixed cushion constructions, such as cushions used for automobile seats.
  • present mattresses usually comprise coil springs which are arranged in side-by-side relationship in the mattress with their respective vertical axes being substantially parallel.
  • the springs are located in separate pockets; however, in the usual case, tie Wires extend transversely throughout the mattress for maintaining the coils in their desired positions. Border wires are also employed for reinforcing the edges of the mattresses and, in addition, panels of material, usually in several layers, are applied over the coil combination.
  • the machinery may include mechanisms for forming coils and for feeding the coils into an assembly construction.
  • additional mechanisms are employed for driving tie wires into association with a plurality of coils for thereby forming the coils into an assembly.
  • FIGURE 1 is a schematic elevational view in section illustrating the technique for cushion and mattress production which characterizes the instant invention
  • FIGURE 2 is a fragmentary sectional view illustrating one alternative form of the invention wherein adhesive tape is employed for securing of the cushion or mattress assembly;
  • FIGURE 3 is a fragmentary view illustrating another alternative of the invention wherein an adhesive printing mechanism is employed for securing of the assembly;
  • FIGURE 4 is a fragmentary sectional view illustrating an alternative of the invention wherein induction heating mechanisms are employed for setting of the adhesive;
  • FIGURES 5 through 8 comprise fragmentary plan views illustrating various adhesive and coil patterns which can be employed in the practice of this invention.
  • FIGURE 9 is a fragmentary perspective view illustrating a suitable coil feed mechanism employed in the practice of this invention.
  • the method of this invention is generally applicable to the production of cushions and mattresses wherein a plurality of coil springs are arranged with their vertical axes in substantially parallel relationship. Panels of material are generally located ⁇ on opposite sides of the construction for engagement with the ends of the coil springs and for purposes of enclosing the coil springs.
  • the invention will be described with reference to mattress constructions although it will be appreciated that generally the same operations are applicable in the ⁇ case of cushions. Although the following discussion relates to the use of exible panels of materials on both sides of the spring assembly, the techniques can -be employed where a relatively rigid member is located on one side, as for example a furniture deck.
  • the width of the panels corresponds to the length of the mattresses which are produced by the method. Accordingly, the completed assemblies can be severed transversely at any desired point depending upon the width of the mattresses to be produced. For any standard length, the same system can be employed with the only variation being in the mechanisms for cutting the assemblies produced.
  • the continuous application of adhesive adjacent to the coil supply location is dispensed with.
  • the adhesive is instead applied at the source of manufacture of the panels or at some other time.
  • An adhesive which will dry on the panels and which can then be reactivated by heat is preferably employed in this case.
  • FIGURE 1 illustrates an arrangement wherein panels of material and 12 are continuously fed from rolls 14 and 16. The panels are moved around guide rollers 18 and then over backing bars 20. The bars 20 are spaced-apart a predetermined distance whereby the facing surfaces 22 of the respective panels will be spaced apart in a desired manner.
  • Coils 24 are adapted to be fed between the moving panels of material.
  • the coils comprise a continuous arrangement including wire members 26 which interconnect adjacent coils.
  • Standard equipment can be employed for producing continuous lengths of individual coils 24.
  • the coils could be connected crosswise of the apparatus whereby entire transverse rows could be fed into the apparatus. It will also Ibe understood that individual, unconnected coils can readily be utilized in achieving the results of this invention.
  • Guide bars 28, also illustrated in FIGURE 9, can be moved for maintaining a desired space between coils in an assembly.
  • the bars include ridge members 30 which define channels 32 corresponding to the approximate width of a coil 24. Lengths of coils, when fed through the use of these guide bars, will maintain a spaced relationship relative to the panels 10 and 12 corresponding to the spacing between the channels 30.
  • FIGURE 1 also illustrates roller coaters 32 and 34 and associated applicator rollers 36 and 38.
  • Combinations of the type shown which can be of any conventional design, are employed for applying adhesive to the surfaces 22 of the panels 10 and 12.
  • the application of the adhesive may involve application substantially entirely over the surfaces 22.
  • selective application of adhesive is contemplated, and various alternatives will hereinafter be described.
  • applicators can be dispensed with if the adhesive is applied to the panels at a separate location.
  • the coils are preferably fed between the panels whereby the coils will be slightly compressed when passing along the area confined by the backing bars 20. This arrangement will serve to hold the coils in a desired position during their passage throughout the mechanism shown. The spacing between the faces 22 of the panels is maintained so that this spacing will not significantly exceed the height of the coils in an unconned state.
  • an assembly which comprises the panels 10 and 12 having coils 24 attached thereto can be continuously produced with the arrangement of this invention. It is contemplated that the length of the mattresses produced could be determined by cutting the assembly transversely at desired intervals whereby the Width of the mattresses will be generally determined by the width of the assembly. It is preferred, however, to employ a system wherein the width of the panels 10 and 12 will correspond to the desired length of a mattress. Accordingly, cuts made transversely of the assembly will determine the width of the mattresses produced. Since a large volume of mattresses are produced in standard lengths but of varying widths, the same construction can be employed for producing all such mattresses with the only variations required -being in the cutting mechanisms.
  • a row of springs could be excluded transversely of the assembly at desired cutting intervals. This can be accomplished by utilizing lengths of coils 24 which are predetermined to correspond to the number of coils desired in a mattress of a given width. If unconnected individual coils are fed into the construction, then it is merely necessary to skip a feeding operation all across the construction for providing a free path for a cutting instrument.
  • the method of this invention is not limited to the use of any particular means for feeding the springs between the panels.
  • the lengths of coils 24 could be fed directly from a conventional machine employed for producing such lengths. On the other hand, it will be obvious that such lengths could be manually fed into the machine. Thus, if 10 rows of springs were necessary, 10 people could be employed for handling of the coils, at least at the initial stage of feeding.
  • FIGURES 2 through 8 illustrate various alternative arrangements, particularly with reference to adhesive application and coil arrangements.
  • the panels 10 and 12 are fed in the same manner and coils 24 are sequentially located between these panels.
  • pressure-sensitive tape 40 is fed between each panel and guide rolls 42 whereby the tape can be applied to the sufaces 22 of the respective panels.
  • double sided pressure-sensitive adhesive tape the tape will secure itself to the faces 22, and in addition, the ends of the coils 24 will be secured to the tape.
  • FIGURE 3 there is illustrated a mechanism suitable for imprinting circles 44 of adhesive onto the faces 22 of the panels 10 and 12.
  • a conventional printing mechanism 46 is illustrated as being suitable for use in the application of adhesive in this manner.
  • FIGURE 4 The arrangement of FIGURE 4 is substantially the same as those previously described; however, in this instance, the adhesive 48 which is applied to the panels comprises an adhesive which is set by means of heat application.
  • a highly suita-ble system for achieving heating includes the use of induction heaters 50, which are adapted to supply heat after the panel and coil assembly is produced. Induction heaters are particularly suitable since they will actually heat the metal coils, the ends of which are in engagement with the adhesive. The heat transmitted by the coil ends to the adhesive causes setting thereof and is effective to produce an extremely satisfactory bond.
  • FIGURES 5 through 8 illustrate adhesive arrangements as well as suitable coil pattern arrangements for mattresses.
  • FIGURE 5 illustrates the manner in which the tapes 40 can be applied to a panel surface 22. It will be noted that the spacing between the tapes is such that every coil will contact at least two of the tapes. With a particularly good adhesive, a one-point contact may lbe suitable; and other obvious variations are also contemplated. The use of tapes is highly desirable since tapes are easy to handle and can be readily applied.
  • FIGURE 6 illustrates the manner in which stripes 62 of adhesive can be associated with the surface 22 of a panel. Again, the stripes are spaced-apart with at least one-point of contact -being provided for each coil.
  • the adhesive pattern shown in FIGURE 7 involves the provision of circles 54 of adhesive as discussed with reference to FIGURE 3.
  • the adhesive may be located on the surface so that the coil ends will correspond to the adhesive circles. It will be obvious, however, that even if exact correspondence is not provided, there will still be ample contact between the coil ends and the adhesive portions.
  • FIGURE 8 illustrates a still further alternative wherein blocks 56 of adhesive are applied to a surface 22. Again, the spacing between the adhesive areas must be such that at least one-point contact is achieved in all instances.
  • FIGURES 5 through 8 are also of interest in that they illustrate the versatility which can be achieved with respect to coil arrangements.
  • the coils are arranged in horizontal and vertical rows.
  • the horizontal rows overlap slightly and a diagonal arrangement is achieved.
  • the interior of the coil arragement differs from the edge arrangement in that the density of coils at the edges is substantially greater. This provides for greater support at the edges which are known to Kbe subject to the greatest tendency toward deformation.
  • Coil arrangements of the type illustrated can be readily achieved with this invention since feeding of coils between the panels can be controlled insofar as the respective rows are concerned. Whether done automatically or manually, there is no need for any particular pattern across the construction since each row can be fed lbetween the panels independently of the other rows. Furthermore, the density across the construction can ⁇ be varied arbitrarily at any given time. This is in contrast to conventional arrangements which must provide careful control with respect to coil location due to the fact that tie wires are employed.
  • Edge reinforcement can be achieved in the manner shown in FIGURE 7; however, the system of this invention is susceptible to the provision of other reinforcing means. It is contemplated that polyurethane foam panels could be aligned all around the side walls of providing edge support. Border wires for interconnecting outer coils can also be employed.
  • an insulating layer may be applied immediately over the coil ends, an intermediate filling material may overlie the insulating layer and, linally, an outer covering may be applied.
  • an outer covering may be applied.
  • the panels 10 and 12 may themselves comprise a suitable final covering material, or they may each comprise a plurality of layers of material with each layer functioning in the manner of the prior art.
  • the instant invention contemplates the use of panels which have an adhesive applied to one surface at a location other than the location of the assembly operation.
  • the adhesive on these panels is of a nature which will not adhere to other surfaces until the coil ends are in position ⁇ against the sur- :face of the panel.
  • various adhesives can be Iapplied to the panel surface which will dry subsequent to application.
  • Such panels can then be employed in the systems described and heating means of the type referred to can then be used for activating the adhesive at the appropriate time.
  • a pressure-sensitive material could be applied to the panel surfaces along with protective strips with the latter being removed prior to contact of the surfaces with the coil ends.
  • the product aspects of this invention contemplate conventional spring insulator materials having adhesive applied on one surface, and s-uch materials may include one element in sandwich arrangements or they may include an assembly of various materials such as the assembly previously referred to.
  • adhesive strips are applied to Tufllex blankets manufactured by the Wood Conversion Company, these blankets comprising a wood fiber bound construction having a cotton net on one side.
  • hot melt adhesives can he applied through the use of various conventional techniques including techniques which involve the use of induction coils as described above.
  • Liquid emulsion adhesives which may require induction heating for driving out solvents and pressure-sensitive adhesives are also entirely suitable.
  • This disclosure is, of course, non-limiting in that contact adhesives of a butyl rubber composition, water emulsion adhesives comprising polymers and copolymers of various resins and vinyls and pressure-sensitive adhesives of the natural or synthetic rubber base type are all contemplated for use.
  • a method for the production of articles comprising cushions and mattresses wherein the articles comprise a plurality of coil springs arranged with their vertical axes in substantially parallel relationship, and including panels of material on opposite sides of said springs overlying the coil spring ends, said method comprising the steps of continuously feeding separate lengths of said material past a coil supply location, maintaining said lengths in spaced-apart relationship with the spacing between lengths being no greater than the normal height of a coil, said lengths of material each being characterized by a continuous application of adhesive material on at least one surface, the surfaces of each length carrying said adhesive material being in opposed relationship at said coil supply location, said adhesive material being applied on discrete por-tions of said surfaces with the spacing between said portions being controlled 'whereby each coil end contacts at least one portion, and continuously feeding said coils between said lengths at said coil supply location whereby said ends of the coils are secured to said lengths.
