Definitions

  • the present invention relates to a device for spreading adhesive films on media having an irregular surface, such as wood boards and the like.
  • These machines have a dosage roller and a rubber-coated spreading roller, which are mutually adjacent so as to define between them a slot for distributing hot adhesive poured between them.
  • the film of adhesive tends to be thicker at the centerline of the rollers, where the deflection is greater.
  • the fact that the spreading roller is rubber-coated increases the unevenness of the film.
  • the rubber sheath itself which yields elastically in order to adapt to the irregular surface onto which the adhesive is to be spread, in fact becomes deformed, at the slot for distribution of the adhesive, by the thrust of such adhesive, which is entrained between the dosage roller and the spreading roller.
  • the aim of the present invention is to provide a spreading device that allows to achieve greater uniformity of the film to be spread on a medium having an irregular surface with respect to that which can be obtained currently with machines of the known type.
  • an object of the invention is to propose a spreading device that allows to spread adhesive onto a medium having an irregular surface so as to obtain thereon a layer that has a more uniform thickness and is at the same time distributed more uniformly than the layer that can be obtained currently with known types of device.
  • Another object of the invention is to propose a spreading device that is structurally simple and easy to use and can be manufactured with low costs.
  • a device for spreading adhesive films on media having an irregular surface such as wood boards and the like, characterized in that it comprises
  • the reference numeral 10 generally designates a device for spreading adhesive films on media 11 having an irregular surface, such as wood boards and the like, which comprises
  • the distribution roller 13 is arranged adjacent to the dosage roller 12 at a predefined distance so as to define with it a distribution slot 19 through which the adhesive film 17 is distributed onto the distribution roller 13.
  • the spreading roller may have a plurality of active portions covered by a sheath.
  • the distribution roller 13 rotates in the opposite direction with respect to the dosage roller 12 and rotates at a second peripheral speed, which is substantially higher than such first peripheral speed.
  • Fluid adhesive 20 is poured at the distribution slot 19 and the dosage roller 12, acting as a doctor, spreads it onto the distribution roller 13 in the form of the adhesive film 17, which has seeped through the distribution slot 19 by way of the combined traction of the dosage roller 12 and of the distribution roller 13.
  • the spreading roller 14 is arranged adjacent to the distribution roller 13, which skims it, rotating in the same direction, in order to receive the adhesive film 17 on the sheath 16.
  • the spreading roller 14 is arranged adjacent to the supporting means 18 of a medium 11 to be spread.
  • the sheath 16 is turned by the spreading roller 14 so as to have a peripheral speed that is equal to a third peripheral speed that is substantially equal to such second peripheral speed.
  • the medium 11 also is advantageously made to perform a translational motion by the supporting means 18 at a tangent speed with respect to the spreading roller that is equal to such third peripheral speed.
  • the adhesive film 17 passes from the distribution roller 13 to the spreading roller 14 and from there to the medium 11, maintaining the thickness defined by the distribution slot 19 and by the differential speed between such first peripheral speed and such second peripheral speed.
  • the supporting means 18 comprise means for moving the medium 11 to be spread with the adhesive film 17, which are adapted to produce its translational motion selectively in an direction that matches or is opposite with respect to the direction of peripheral rotation of the spreading roller 14, and comprise selectively, alternately or simultaneously,
  • the dosage roller 12 and the distribution roller 13 have a different hardness of their lateral cylindrical surface, so as to avoid their seizure in case of accidental mutual contact of the surfaces.
  • both the dosage roller 12 and the distribution roller 13 are made of metallic material and have a surface layer which is hardened, for example by thermal or thermochemical treatment.
  • At least one between the dosage roller 12 and the distribution roller 13 is made of metallic material and has a surface layer that is hardened, for example by thermal or thermochemical treatment.
  • the distribution roller 13 has a surface hardening covering.
  • the active portion 15 of the spreading roller 14 advantageously is a substantially central cylindrical portion of the spreading roller 14.
  • the operation of the spreading device 10 according to the invention is as follows.
  • the dosage roller 12 and the distribution roller 13, arranged adjacent so as to form between them the distribution slot 19, are turned respectively
  • the rollers 12 and 13 rotate in opposite directions, so that such first and second peripheral speeds respectively have a first direction A and a second direction B, which are opposite and are such as to induce traction between the dosage roller 12 and the distribution roller 13 of adhesive 20 that has poured between them.
  • the distribution roller 13 entrains on its surface the adhesive film 17 formed by the adhesive 20 that has passed through the distribution slot 19.
  • the adhesive film 17 that is formed between them is more uniform than the adhesive films that are formed between the dosage roller and the rubber-coated spreading roller of currently known spreading devices for wood media.
  • the spreading roller 14 rotates in a third direction C, which is the same as the second direction B of rotation of the distribution roller 13, skimming, with the sheath 16, simultaneously
  • the sheath 16 Since the sheath 16 is elastically yielding, it adapts easily to the surface irregularity of the medium, depositing thereon the adhesive film 17 in a layer that is more uniform and homogeneous than the layers of adhesive deposited by means of currently known devices for spreading wood media.
  • a spreading device 10 has been exemplified schematically in solid lines wherein the medium 11 performs a translational motion in a first sliding direction D, which matches the third direction C of rotation of the spreading roller 14; however, according to the contingent requirements, in alternative embodiments of the invention the support can perform a translational motion in a second sliding direction E, which is opposite to the first sliding direction D and therefore is discordant with respect to the third direction C of rotation of the spreading roller 14, as shown by way of non-limiting example in dashed lines in Figure 1 .
  • the invention achieves the proposed aim and objects, providing a spreading device that allows to achieve greater uniformity of the film to be spread on a medium having an irregular surface with respect to the one that can be obtained currently with devices of the known type.
  • a spreading device allows to spread adhesive on a medium having an irregular surface so as to obtain thereon a layer that has a more uniform thickness and simultaneously is distributed more uniformly with respect to the layer that can be obtained today with devices of the known type.
  • a spreading device according to the invention is structurally simple and easy to use and can be manufactured with relatively low costs.
  • the materials employed may be any according to requirements and to the state of the art.
