Definitions

  • the invention relates to a method for edgebanding a panel, in particular a composite panel with a light structure, and a panel so obtained.
  • Composite panels with a light structure are known, which are, for example, used for making furniture, shelving, shelves, doors and the like, provided with a layered or a "sandwich" structure.
  • This structure comprises an intermediate layer interposed between a first external layer and a second external layer, that are substantially flat and mutually opposite, and are made of wood or similar materials.
  • the intermediate layer is made of a filling material, made of wood or similar materials, such as, for example, cardboard sheets having a honeycomb structure, that is lighter and less resistant than the material used for making the first and the second external layer.
  • These panels are also provided, at edge portions thereof, with a longitudinal groove, for example having a trapezoidal or rectangular-shaped cross section, obtained by suitably milling the edge portions, in particular by milling the intermediate layer, the first external layer and the second external layer.
  • This groove extends from the intermediate layer up to the first and the second external layer, on internal sides of which notches are formed that are opposite one another.
  • Such notches are arranged, in use, for acting as stop seats for a supporting element, or list, arranged for being received in the aforesaid groove.
  • the supporting element which is made of wood or similar materials, has a cross section of the same shape as that of the groove and it is arranged for reinforcing and strengthening the edge portions of the panel and for supporting an edge element made of plastics or similar materials.
  • the edge element in use, is supported by and abuts on an abutting surface of the panel, defined by a first face of the supporting element, opposite a second face of the supporting element facing a bottom wall of the aforesaid groove, and by respective head surfaces of the first and of the second external layer, the first face and the head surfaces facing the edge element.
  • edge portions of the panel are milled by means of a second milling apparatus, to obtain the aforesaid groove.
  • this first edgebanding apparatus comprises first cutting means for cutting to a desired length said supporting element, a first glue distributing element arranged for distributing a first layer of glue on respective side surfaces of the aforesaid supporting element and a first pressing roller that presses and inserts the supporting element into the groove.
  • a milling apparatus grinding the abutting surface by a milling apparatus, after which gluing the edge element on the abutting surface is provided and subsequently to cut the edge element to a desired length by a second edgebanding apparatus.
  • this second edgebanding apparatus comprises second cutting means for cutting to a desired length said edge element, a second glue distributing element arranged for distributing a second layer of glue on an active surface of the edge element facing the aforesaid abutting surface, and a second pressing roller that presses the edge element on the abutting surface.
  • removing an upper part and a lower part of the edge element that exceed the abutting surface by means of a trimming apparatus making, by means of an edging apparatus, a connecting radius between the edge element applied to the abutting surface of the panel and the respective outer surfaces of the first and of the second external layer, and lastly rounding, by a rounding/profiling apparatus, the profile of the edge element after the edge element has been applied to the panel.
  • a drawback of this method is that it is extremely slow and laborious to actuate, which implies low productivity with consequent loss of money.
  • a further drawback of this method is that it requires at least two edgebanding apparatuses to be made, in addition to a grinding apparatus, which involves an increase in the expenses to be sustained that are connected therewith, such as the purchase and maintenance cost thereof.
  • An object of the invention is to improve a method for edgebanding a panel made of wood or similar materials, in particular a composite panel.
  • a further object is to provide a method for edgebanding panels that is quicker, simpler and cheaper to be implemented than known methods.
  • Another object of the invention is to improve the panels, in particular composite panels with a light structure.
  • a method for edgebanding a panel made of wood or similar materials comprising machining an edge portion of said panel to obtain seat means, inserting into said seat means a supporting element and fixing on said supporting element an edge element, characterised in that before said inserting there is provided said fixing and in that there is provided cutting said supporting element and said edge element to desired lengths.
  • this method provides fixing said edge element on said supporting element before inserting said supporting element in said seat means.
  • this method provides cutting said edge element and said supporting element to desired lengths.
  • this method does not require a grinding apparatus and needs only a suitably modified edgebanding apparatus.
  • this enables the costs to be sustained for applying this method to be diminished and on the other hand enables the overall dimensions of an apparatus that is usable for applying this method to be reduced.
  • a panel made of wood or similar materials provided with an intermediate layer interposed between a first layer and a second layer, and with an edge portion, in which there is obtained a seat comprising a bottom wall, characterised in that said bottom wall consists of an end wall of said intermediate layer and in that there is provided a supporting element arranged for being received at least partially in said seat and for supporting an edge element of said panel, said edge element and said supporting element being provided respectively with an end portion and with a further end portion for defining a corner zone of said panel.
  • a panel 1 which is usable for making furniture, shelving, shelves, doors and the like, comprising a layered or "sandwich" structure 2.
  • the structure 2 comprises an intermediate layer 3 interposed between an external first layer 4 and an external second layer 5, that are substantially flat and mutually opposite, that are made of wood or similar materials.
  • the intermediate layer 3 is made of a filling material, made of wood or similar materials, such as, for example, cardboard sheets having a honeycomb structure, that is lighter and less resistant than the material used for making the first layer 4 and the second layer 5.
  • the panel 1 is further provided, at edge portions 6 thereof, with a seat 7, extending substantially longitudinally ( Figure 1 ).
  • the seat 7 has a substantially trapezoidal cross section, and is obtained, as disclosed better below, by suitably milling the edge portions 6.

  • the bottom wall 12, the first side wall 16 and the second side wall 17 consist respectively of an end wall 45 of the intermediate layer 3, of a first tilted wall 46 of the first layer 4 and of a second tilted wall 47 of the second layer 5.
  • the panel 1 comprises a seat having a substantially rectangular-shaped section obtained by compressing the third end portion 20 of the intermediate layer 3.
  • the seat 7 is arranged, in use, to receive a supporting element 8, in the shape of a list or strip made of wood or similar materials, having a cross section that is substantially the same as that of the seat 7 and arranged for reinforcing and strengthening the edge portions 6 of the panel 1 for supporting an edge element 28 having a thickness S1 ( Figure 5 ).
  • the supporting element 8 comprises a side 11 facing and arranged for contacting in use the bottom wall 12, a further side 13 opposite the side 11, a first side surface 14 and a second side surface 15, that are mutually opposite, facing in use respectively the first side wall 16 and the second side wall 17 of the seat 7.
  • the supporting element 8 further has a further thickness S2 that is larger or smaller according to whether in a first external surface 9 and/or in a second external surface 10 respectively of the first layer 4 and of the second layer 5, within a certain distance D from the edge portions 6, holes and/or millings that are not shown should or should not have to be made.
  • pins may be engaged, which are not shown, projecting from the first external surface 9 and/or from the second external surface 10 and arranged for supporting, for example, a shelf, or fixing means, which are not shown, arranged for fixing elements such as hinges to the panel 1.
