Definitions

  • the present invention relates to a method of making a mattress from a raw plate of latex, as well than a bedding mattress obtained by such a process.
  • the object of the present invention is to eliminate the disadvantages above by proposing a method of production of a mattress from a raw plate of latex which may have dimensions such as those of mattresses do not meet the usual standards and which is characterized in that it consists in placing the plate raw latex in a rigid frame forming a template predetermined dimensions such that the frame compresses the raw latex plate; to be fixed above a face top of the raw compressed latex plate, by example by gluing, a coating of high rigidity of so as to maintain at least the width or length of the raw latex plate, when the latter is removed from the template frame, at a value substantially equal to that of the width or the predetermined length of the template frame for get a width or length of mattress normalized.
  • the method consists in fixing the aforementioned rigid coating directly on the face upper of the raw plate of compressed latex; at invert the raw latex plate in the forming frame template; and attach directly to the underside of the raw latex plate, for example by bonding, a other coating of high rigidity, so as to maintain the width and length of the raw latex plate, when the latter is removed from the frame forming gauge, at substantially equal values respectively at the predetermined width and length values of the frame forming a template for making a mattress standard dimensions.
  • Each rigid covering is glued over the entire surface corresponding to the raw latex plate.
  • each rigid covering is glued on the periphery of the corresponding surface of the raw latex plate.
  • the method consists in frame the raw latex plate with sections longitudinal and transverse, at least both of which longitudinal sections are made of a more rigid material than the latex of the raw plate; to fix, for example by gluing, the two longitudinal sections at the edges corresponding lengths of the raw latex plate and at the corresponding ends of the sections transverse; to place the assembly thus formed in the frame forming a template; to fix the aforementioned coating in the form of a transverse strip directly over two opposite corresponding upper face portions respectively of the two longitudinal sections; at return the assembly in the frame forming a template; and to attach, for example by gluing, another coating of high stiffness in the form of a transverse strip directly on two portions of lower faces opposite correspondents of the two longitudinal sections so as to maintain the width and length of the raw latex plate, when the latter is removed of the frame forming a template, at values substantially equal to the width and predetermined length of the template frame for make a mattress of standardized dimensions.
  • the longitudinal and transverse sections are made of high density polyether foam material.
  • the aforementioned rigid coatings are made of a non-woven material with a weight ranging from 40 g / m 2 to 100 g / m 2 and an elongation less than or equal to 2%.
  • the invention also provides a bedding mattress comprising an internal latex plate and which is characterized in that it comprises at least one coating of high rigidity fixed above a face of a plate internal compressed with latex, for example by bonding, so as to maintain at least the width or length of the plate latex to a standard width or length of the mattress.
  • the rigid coating above is fixed directly on the corresponding face latex plate and another stiffness coating high is fixed directly, for example by gluing, on the opposite side of the latex plate, so that maintain the width and length of the latex plate at normalized width and length values of mattress.
  • the mattress comprises longitudinal and transverse framing sections of the latex plate, the longitudinal sections of which are fixed by gluing to the longitudinal edges latex plate correspondents and ends corresponding cross sections, the sections longitudinal with higher rigidity than latex, the aforementioned rigid covering being in the form of transverse band fixed by gluing directly on two opposite corresponding upper face portions respectively of the two longitudinal sections and one other cross-shaped covering is attached by bonding directly on two portions of faces corresponding corresponding lower respectively two longitudinal sections so as to maintain the width and length of the latex plate at standard width and length values of the mattress.
  • the longitudinal and transverse sections are made of high density polyether foam material and the aforementioned coverings are made of a non-woven material with a weight ranging from 40 g / m 2 to 100 g / m 2 and of less or equal elongation. at 2%.
  • Figures 1 and 2 show in longitudinal section two latex sheets, respectively dimpled and perforated each intended for the production of a mattress bedding.
  • Figures 3 and 4 show different stages of the process of the invention allowing the production of a standard size mattress including the plate Figure 1 latex.
  • FIG. 5 represents the latex plate of the invention obtained by the method of FIGS. 3 and 4.
  • Figure 6 is a view similar to that of Figure 5 and representing the latex plate of Figure 2 including the precise dimensions are obtained by the steps of method of the invention to satisfy the dimensions standard of the mattress comprising such a plate.
  • Figure 7 is a perspective view of another mode of realization of an internal mattress plate of dimensions precise obtained by the process of the invention for make a mattress of standardized dimensions.
  • Figure 1 shows a longitudinal section of a plate of latex 1 of the cell type 2 intended to produce a standard size mattresses which can be, for example example, 190 cm in length and 140 cm in width.
  • the latex plate 1 is placed in a rigid frame forming a template 3 of predetermined dimensions such that the frame compresses the raw latex plate 1.
  • the frame may have dimensions of 187 cm in length and 137 cm in width to make a mattress of real standard dimensions of 188 cm in length and 138 cm in width, the dimensions mentioned above of the mattress, that is to say 190 cm in length and 140 cm in width, being in fact the commercial dimensions. Because the latex plate 1 has been cut to the dimensions of 190 cm x 140 cm with a tolerance of ⁇ 2 cm, the positioning of the plate 1 in the frame 3 compresses the plate.
  • a tear-resistant coating 4 preferably of non-woven material with a grammage ranging from 40 g / m 2 and 100 g / m 2 , is fixed by bonding to the raw latex plate compressed 1.
  • the coating 4 of rigidity greater than that of the latex is fixed by gluing on the periphery of the upper face of the plate 1, but of course this coating can be glued on the entire upper surface of this- this.
  • the whole of the latex plate 1 and of the rigid coating 4 is turned over in the frame forming a template 3 and another coating 5 of high rigidity identical to that of the coating, preferably in a non-woven material of grammage ranging from 40 g.
  • the covering 5 is fixed to the periphery of the underside of the latex plate 2 but it can also be attached to the entire underside thereof.
  • the latex plate 1 Once the latex plate 1 removed from the frame 3, it retains practically the same dimensions as those of this part of the fact that the two coatings 4, 5 have a very high rigidity, i.e. properties elongation in longitudinal and transverse directions extremely low, for example less than 2%. So, the latex plate 1, thanks to the rigid coatings 4 and 5 has dimensions of 187 cm x 137 cm for tolerances of ⁇ 0.5 cm, which allows compliance with tolerances for making mattresses according to standards currently in force and established at ⁇ 1 cm. The latex plate 1 thus produced makes it possible to control perfectly and quickly the realization and the finish of the mattress.
  • the manufacturing process of the latex plate 1 provided with its rigid coatings 4, 5, -allows returns to the after-sales service latex plate mattress with too short ribs and also to avoid the return of mattresses to after-sales service due to sagging edges of the mattress due to a re-cut latex plate.
  • Figure 6 shows the realization of a latex plate of the perforated type such as that shown in FIG. 2 produced under the same conditions as the latex plate 1 of Figure 1 for fixing via the frame forming a template 3 of the high rigidity coatings 4, 5 to maintain the length and width of the plate to values allowing the realization of the mattress meeting current standards.
  • FIG. 7 represents an alternative embodiment of a raw latex plate 1 for example of the perforated type and arranged to produce mattresses of dimensions standardized.
  • This alternative embodiment also makes it possible to reduce the dimensions of the latex plates in order to reduce the cost of latex, which is a very expensive material.
  • the latex plate 1 comprises longitudinal 6 and transverse 7 sections framing the plate 1 and of which at least the two longitudinal sections 6 are made of a more rigid material than the latex of the raw plate 1.
  • the longitudinal sections 6, like the transverse sections 7, are made of a high density polyether foam material, for example 28 g / m 2 .
  • the longitudinal rigid sections 6 are fixed by gluing respectively to the two longitudinal edges of the latex plate 1 and the two transverse sections 7, only one of which is shown in FIG. 7, are fixed by gluing, at their ends, between the two corresponding parts of longitudinal sections 6 projecting from the plate 1.
  • a coating 8 of higher rigidity than latex and tear-resistant preferably in a non-woven material having a grammage of 40 g / m 2 to 100 g / m 2 , is produced in the form of a transverse strip and fixed by bonding directly on two portions of corresponding upper faces opposite respectively of the two longitudinal sections 6.
  • Another identical strip-shaped covering (not shown) is also fixed by gluing to the opposite face of the latex plate 1 directly on two portions of corresponding lower faces opposite respectively of the two longitudinal sections 6.
  • Each of the two rigid coverings may have a width of approximately 500 mm.
  • the two rigid covering strips ensure the keeping the width of the latex plate at a value to satisfy the standard width value of a mattress, while the two longitudinal sections rigid 6 maintain the length of the latex plate 1 at a value allowing a standard length mattress.
  • This embodiment is advantageous since by providing a frame with longitudinal and transverse sections of plate 1, the latter may have dimensions reduced, for example by a length L of 180 cm and a width l of 120 cm instead of 190 cm and 140 cm, i.e. a reduction in latex material of 18.8%, for a width 11 of a longitudinal section 6 of 10cm and a width 12 of transverse section 7 of 5 cm.
  • the central area of the latex plate usually reinforced with denser latex to firm the mattress can be ensured thanks to the reinforcing effect of two coverings 8 in non-woven strips bonded to the two longitudinal sections 6, which decreases by about 3 at 4% the latex material usually used in the central area of plate 1, for a total gain in latex greater than 20%.
  • the plate 1 and its longitudinal sections 6 and transverse 7 shown in Figure 7 is made in a frame forming a template of the kind shown in Figures 3 and 4 to allow this set to be brought to dimensions allowing the realization of a mattress with standard dimensions.
  • the plate 1 provided with its longitudinal 6 and transverse 7 sections are placed in the frame forming a template whose dimensions determined allow to compress this set to values such as when the assembly is removed from the frame forming a template, the dimensions of this set are substantially equal to those of the framework to achieve the mattress with standardized dimensions.
  • a strip transverse non-woven covering 8 is fixed by bonding on two corresponding parts of the sections longitudinal 6 coming into contact on the face top of plate 1. Then the assembly is returned to the frame to glue the other coating in strip form of non-woven material on both sides corresponding to the longitudinal sections 6.
