Definitions

  • the present invention relates to a an edgebanding apparatus, in particular an edgebanding apparatus for an edgebanding operating machine, suitable for applying strips, tapes, listels, rods of differing stiffness and elasticity to edges of elements such as panels, tables, shelves.
  • Known edgebanding apparatuses essentially comprise a supply unit that is able to supply a gluing roller and a pressing roller or feeder with a thin strip or a straight listel.
  • the gluing roller applies glue to the side of the strip intended for abutting the edge of an element or panel, or to the edge itself.
  • the pressing roller moves, positions and compresses with the necessary force the strip on the edge to achieve and consolidate the fixing thereof.
  • the pressing roller is motor-driven and by rotating feeds and moves the strip.
  • Both the glue and pressure rollers are fixed to a work surface, on which the element to be edgebanded is positioned.
  • Guides and combs are also provided that support and guide the strip up to the joint or abutment point with the edge of the element.
  • the distance between the joint point and the gluing roller, and therefore the distance between the gluing roller and the pressing roller, must be as small as possible. This in fact enables the time to be reduced that elapses between distribution of glue onto the strip and the abutting of the latter on the edge, and therefore the time of exposure of the applied glue to the air.
  • the work or incidence angle that the strip forms with the edge of the element at the joint point must be sufficiently wide as the wider this angle is the less the distance between the two rollers can be.
  • the width of the work angle is generally comprised between 45°and 60°.
  • Edgebanding apparatuses that use thin and flexible strips or belts are not, however, able to perform edgebanding with stiff listels or rods that are less deformable and/or fragile, for example straight listels of solid wood with a thickness that is greater than 2 mm. Said listels have to be bent along curves of wide radius and can be applied using work angles with a reduced width, less than 30°. Generally, for these listels/rods specific edgebanding apparatuses have to be used.
  • An object of the present invention is to improve known edgebanding apparatuses, in particular by increasing the versatility and flexibility of use thereof.
  • Another object is to obtain an edgebanding apparatus that is able to apply strips, belts, listels having differing stiffness and elasticity.
  • a further object is to obtain an edgebanding apparatus that enables a strip to be fixed to the edge of an element with great precision and reliability.
  • an edgebanding apparatus for fixing a strip to an edge of an element in wood or similar material, comprising gluing means, suitable for applying adhesive to said strip or to said edge, and pressing means, suitable for pressing said strip to said edge, characterised in that it comprises a plurality of fixing means suitable for removably connecting said pressing means to a work surface configured for supporting said element.
  • the fixing means in fact enables the pressing means to be locked in different work positions in such a way as to be able to bend the strips, listels on the edge to be machined with different work angles, according to the features of the strip, and in particular the greater or lesser flexibility, elasticity, fragility of the latter.
  • an edgebanding apparatus 1 suitable for fixing a strip 25 to an edge 20a of an element 20 in wood or similar material, typically a straight or round, shaped curved panel.
  • the apparatus 1 comprises gluing means 9, suitable for applying a glue to a face of said strip 25, and pressing means 2, suitable for pressing said strip 25 to said edge 20a and making it adhere thereto.
  • the gluing means 9 includes a gluing roller of known type, which is able to distribute for example a thermofusible glue to the strip 25.
  • the gluing means 9 is arranged to apply the glue directly to the edge 20a of the element 20.
  • the apparatus 1 comprises a plurality of fixing means 4 configured for removably connecting the pressing means 2 to a work surface 3, intended for supporting said element 20.
  • the pressing means 2 comprises a pressing roller 12, of known type, that is rotatably connected to one of the fixing means 4.
  • the pressing roller 12 is rotated around a respective axis 12a by driving means, of known type and not illustrated in the figures.
  • the axis 12a is fixed and almost perpendicular to the work surface 3.
  • Each fixing means 4 may, for example, comprise a grooved hub 4a, inside which there can be inserted a corresponding shaft of the pressing roller 12.
  • the grooved hub 4a is connected to the driving means and by rotating transfers motion to the respective pressure roller 12.
  • the fixing means 4 are distanced from one another and arranged at an increasing distance from the gluing means 9. As illustrated in figure 1, the fixing means 4 can be arranged equidistantly along a rectilinear direction A, or be staggered in several directions, for example parallel directions. In this way it is possible to place the pressing roller 12, which may have variable radial dimensions, in different work positions, at different distances from the gluing means 9, according to the features of the strip 25 to be applied.
  • the pressing means 2 comprises a plurality of pressing rollers 12, for example two, rotatably fixed to respective fixing means 4 and acting jointly on the strip 25.
  • the use of two pressing rollers 12 has proved to be particularly advantageous because it enables the gluing process to be optimised.
  • the two rollers in fact enable the strip 25 to be kept pressed on the edge 20a along a compression portion B with a length that is greater than that of the compression portion that is obtainable with a sole pressing roller.
  • the length of the portion B which substantially corresponds to the distance between the two pressing rollers 12, can be defined according to specific needs, fixing said pressing rollers 12 to respective appropriate fixing means 4.
  • the use of two pressing rollers 12 also enables the speed of application of the strip 25 to the edge 20a to be increased without increasing compression time, with a consequent increase in the output of the apparatus 1.
  • edgebanding apparatus 1 of the invention may also comprise three of more pressure rollers 12 in order to obtain compression portions B of variable length.
