Definitions

  • the present invention relates to a method of manufacturing a box or cabinet as well as the production line and the box or cabinet obtained.
  • This type of box includes a box body with a cover mounted telescopically on the end of the box body.
  • the manufacturing process for this type of box consists of winding several layers of paper helically around a longitudinal axis using a shaping mandrel and a conventional winding machine.
  • An internal tube is then produced in an external tube, then cutouts are made from the outside to the inside so as to cut the layers from the external tube to the internal tube and then from the inside to the outside so as to cut the layers from the inner tube outwards to the outer tube.
  • tops and bottoms closing the internal and external tubes forming the box body and the cover may for example be metallic and are of known type. They allow the complete closure of the box.
  • this manufacturing process it is planned to wind four layers of paper and only the second and the fourth layers have an adhesive internal coating so that there is no adhesive present. between the two inner layers and the two outer layers.
  • industrial manufacturing provides for the production of very long tubes which are cut to the dimensions of the boxes to be obtained, each of these sections being treated as indicated above so as to produce a box in sections.
  • wood is a noble material and that its very texture gives it, in particular for certain species, a refined aesthetic, both by its visual appearance and by the touch it provides.
  • wood Another advantage of wood is the fact that it can receive different forms of "printing" both reported, like labels, and produced in the mass by direct printing in particular.
  • distributors are looking for shapes of revolution and with interlocking of the cover on the body without protrusion of one of the elements relative to the other.
  • the object of the present invention is to propose a manufacturing process which makes it possible to produce such packaging, in particular for luxury products, which can be produced from sheet materials, including peeled or sliced wood, which has no part protruding during the fitting of the cover on the box body, which has good mechanical strength, which can be made wider than tall or taller than tall indifferently and the steps of which can be automated.
  • the invention also relates to the production line of this box which makes it possible to implement the method, this line comprising an original succession of machines of known type.
  • the invention also relates to the box thus obtained which has a section of revolution, but whose profile can vary infinitely.
  • the first strip has a height L ' of between l and L.
  • the beveled end overlap areas are sanded so as to limit the excess thicknesses.
  • each strip has a length equal to n times the perimeter so as to produce a cover and a box body with n layers each.
  • any indications relating to the product are deposited on the peripheral strip, on the top as well as on the bottom.
  • the box comprises outer layers of the box body and of the cover made of noble essence while the intermediate layers when making multilayer boxes is in essence economical.
  • Figure 1 there is shown schematically the different stages of manufacturing a box according to the invention, these steps being referenced by the letters A to J.
  • the method is described in a simplified manner and makes it possible to produce a so-called simple box with a single layer as will be described later.
  • Step A consists of preparing the material sheets for the subsequent steps.
  • step B the plate 10 intended for manufacturing the first strips is then sanded bevel by means of an inclined belt sander 26, likewise the plate 12 is also sanded on the opposite side by a inclined belt sander 28.
  • the plates 14 and 16 do not undergo any additional mechanical treatment.
  • step C the plate 10 is cut to generate several first strips, only one of them being shown for the simplification of the diagram.
  • plate 12 it is also planned to cut the second strip 32, but this is generally printed and has a mention 34.
  • the plates 14 and 16 are marked with a view to their cutting, the plates 14 being provided for making the plates 36 from above and 38 from below, while in the plate 16 there is provided to realize the bodies 40 and 42 of the top and bottom of the box.
  • step D there is therefore a first strip 30, bevelled in its part 31, a second strip 32, bevelled in its part 33 and presented inverted, the mention 34 then being shown in broken lines.
  • top and bottom plates, respectively 36 and 38, are also shown turned over, while the top and bottom bodies 40 and 42 are shown in the same position as in the previous step C , but cut out.
  • Step E corresponds to the abutment of the first strip with the second and to the mounting of the bodies of the top and bottom of the box, on the tackles of the top and bottom of the box.
  • This assembly is generally carried out by simple bonding.
  • step E provision is also made for gluing the first and second strips before the subsequent winding step.
  • the two bands have a width L , and lengths respectively P1 for the first band and P2 for the second band with P2 greater than P1 so as to take account of the increase in diameter during the subsequent winding as it will be described later.
  • the two strips are abutted using an adhesive tape 44, placed on a height l which determines the exterior height of the box body.
  • the overlap zone ⁇ is located at the end of the first strip and juxtaposed with the abutment zone.
  • the second strip is coated with glue over its entire length P2 and over a height l , as well as over the entire overlap zone situated at the free end of this second strip and referenced ⁇ .
  • This glue zone is referenced 46.
  • step F the first and second abutting strips are wound on themselves, the first strip 30 then substantially forming a tube with the overlap zone ⁇ , while the second juxtaposed strip comes to wind up concentric to form a second tube with the overlap zone ⁇ .
  • part 46 comprising adhesive makes it possible to secure the first and second tubes to one another.
  • Figure 5 there is shown an elevational view with a dashed line representation of the inner walls of the box body.
  • step G it is planned to sand and mill the can body thus obtained, so as to create an upper 52 and lower 54 over-bore, using a milling machine 50, the assembly being sanded using a sander 48.
  • the top and bottom of the box can be arranged in the upper and lower part of the box body because the top box body 40 and the bottom box body 42 penetrate inside. of the second tube and are positioned in abutment on the walls of the first tube thanks to the over-bores 52 and 54.
  • top and bottom plates are flush with the upper and lower part of the box body and protrude outside.
  • a peripheral sanding represented by step I makes it possible to obtain a box body without any projecting element.
  • Step J is the final step which consists in cutting the box body and only the outer tube along line 56, discontinuous shown in FIG. 1, in order to separate the upper part of the second strip 32 which forms the peripheral wall of the cover, this cover being completed by the box top body 40 and the box top plating 36.
  • the actual body of the box comprises the lower part of the second strip provided with the adhesive 46 as well as the first inner tube corresponding to the winding of the first strip, the cover coming to cover this first tube telescopically.
  • FIG. 6 shows a multilayer variant in which the first strip is made up of three parts 60, 62, 64, the second strip itself being made up of three parts 66, 68 and 70.
  • the first strip has a width L ' , the width L' being itself greater than the width l corresponding to the height of adhesive of the gluing zone 72 of the first part 66 of the second strip.
  • FIG. 7 The winding of these two multilayer strips is shown in Figure 7 in which we find the first inner tube with the succession of layers 60, 62, 64 glued to each other, then the successions 66, 68, 70 also glued to each other, the strip 66 being itself glued to the strip 64 over a height l .
  • a peripheral cut 71 is provided for the three layers thus formed 66, 68, 70, at a height greater than 1 in order to separate the upper part 72 forming the cover from the lower part 74 forming the body of the box.
  • the top 76 of the cover 72 is substantially more elaborate than the cover described in the first embodiment in the sense that it comprises an upper plating 78 and a lower plating 80 on either side of the body 82 of the can top.
  • the inner tube being of a height L ' less than L , it is possible to directly fit the cover top 76 by cutting the box top body and the lower veneer sheet 80 to the exact inner profile of the second tube , while the upper plating 78 of the cover top 72 is cut to dimensions greater than the external dimensions of the cover 72 and possibly sanded to refine the embodiment.
  • Figure 8 shows the lower part of the box body 74 where we find the succession of layers 60, 62, 64; 66, 68, 70 with interposition of glue between each, the middle layer being symbolized in a more pronounced manner in this representation.
  • the underside of the box 84 comprises, in an identical manner to the top of the cover 72, a body of the underside of the box 86, a lower plating 88 and an upper plating 90.
  • the plating 90 has the same dimensions as the lower plating 80 of the top of the box, while the lower plating 88 has the same dimensions as the upper plating 78 of this can top.
  • box bottom body 86 As for the box bottom body 86, it is of identical dimensions to the box body 82 of the cover top 72.
  • the first tube made up of the layers 60, 62, 64 can be milled in order to achieve a recess relative to the second tube or more simply, the first strip can comprise a reduction in its width L ' at its lower part.
  • the species of wood when it is an embodiment in this material, may be different depending on the parts which constitute the first and the second strip.
  • part 60 is made of noble material just like the third part 70 of the second strip, these parts being the visible interior and exterior parts of the box and it is the same for the top and bottom plating of box which will be made from noble essences, the body of the top and bottom of the box as well as the intermediate layers being made from more economical wood.
  • FIG. 9 there is shown a bench 100 provided with a pusher-puller 102 for supplying the abutting strips, referenced 104
  • This winding bench 100 comprises a central mandrel 106 of the desired box shape, this mandrel having adjustment means 108 making it possible to vary the external shape of this mandrel.
  • the box has an ovoid shape and this mandrel is rotatably mounted in the direction indicated by the arrow 110 by means of a rotating plate 92.
