Definitions

  • the invention relates to a method for gluing toothed butt edges of veneer strips to be connected, wherein teeth of one piece of veneer are inserted into tooth gaps of the piece of veneer to be attached and in this position are connected by glue applied in the joint between the two toothed butt edges, the glue first being on one Application area is applied and at least one of the veneer strips is then pushed over this application area, whereby its front abutting edges are wetted with glue.
  • the glue strip or the like be dosed so that when the veneer pieces and their teeth are brought together, about half of the flanks of the teeth, starting from their tips, are wetted with glue.
  • the areas of the teeth of the one veneer piece wetted with glue can in turn provide the areas of the tooth gaps that are no longer wetted with glue with glue or lead there to corresponding gluing.
  • At least the joining area can be pressed against the application surface and preferably heated. It is particularly expedient if the veneer strips are heated after they have been brought together on their upper side facing away from the glue application surface.
  • the heating and pressing accelerates the setting process and improves the gluing.
  • the simultaneous pressing improves the heat transfer. This acceleration of the curing of the glue enables faster cycle times.
  • the glue application device as an application nozzle, application roller or wheel or the like. be trained. So while a metered glue strip or a row of metered glue spots on the application surface or plate with the help of an application nozzle or the like. attached, the upper limit and guide to hold down the pushed edges and end faces of the veneer pieces is not in the way.
  • the press beam is heated.
  • the heating power and heat are then transferred particularly well to the gluing point, so that a quick curing of the glue and thus short cycle times are possible on this device.
  • the press beam advantageously has a preferably adjustable distance from the glue application plate, for example approximately from the thickness of the veneer strips to be glued. This ensures the desired guidance for the glue pieces and yet does not hinder their merging. Due to the adjustability of the distance of the press beam from the glue application surface, it is possible to adapt to veneer strips of different thicknesses.
  • the glue application plate or the like can increase on its surface at the edges lying transversely to the feed of the two veneer strips.
  • the glue application device already mentioned is expediently arranged transversely to the direction of movement of the Veneer pieces arranged center of the application plate, which is made in particular of metal, can be moved and can preferably act on a fraction of the width of the application surface, in particular in its central section.
  • both veneer pieces or strips on the side of the glued zone of the application surface receive approximately the same sliding path when they are joined together and can then take up about half of the glue with their abutting edges from the single glue strip.
  • the device according to claim 7 differs from that according to claim 6 essentially in that the application plate is movable relative to the - appropriately dimensioned - glue application device transversely to the direction of movement of the veneer pieces, in order to be wetted with glue in a defined width or strip zone .
  • the width of the guide or of the press beam which extends in the direction of movement of the veneer pieces when they are pushed together, can preferably correspond to at least about a quarter of the length of the teeth provided on the veneer pieces and can be pushed into one another, and the guide surface of the guide or of the press beam facing the veneer pieces can be parallel to the application area. This is sufficient for good guiding and pressing of the teeth after the veneer strips have been pushed together.
  • the width of the guidance or of the pressure beam corresponds to approximately one third to half the length of the teeth of the veneer pieces or to approximately the entire length of these teeth.
  • FIG. 1 is first applied as a glue strip 6 on an application surface 7 and then at least one of the veneer pieces 2 or 3 is pushed over this application surface 7, as indicated by the arrows Pf 1 in FIG. 1 and opposite 1 modified arrangement of the veneer pieces 2 and 3 in Fig. 2 is indicated.
  • Figures 2 and especially 4 show that the front abutting edges of the teeth 4 are at least partially wetted with the glue.
  • the procedure is such that the two veneer pieces 2 and 3 with a flat side, in the exemplary embodiment of their underside, and opposing teeth 4 on the application surface 7 are initially arranged at a distance from one another, as is also shown, for example, in FIG. 3, during Fig. 1 represents an even greater distance between these veneer pieces 2 and 3 before they reach the application surface 7.
  • the metered glue strip 6 possibly also a series of glue spots or spots — is applied, this process being in progress in FIG. 1 and a corresponding glue application device 8 transversely to the longitudinal extent the veneer pieces 2 and 3 are moved over the application surface 7, their metering device 9 dispensing the glue strip 6 and arranging it on the application surface 7.
  • FIG. 4. 2 and 3 in particular illustrate that the two veneer pieces 2 and 3 are pushed towards one another and moved in equal parts by the glue strip 6.
  • This glue strip 6 is dosed by the metering device or dispenser 9 of the glue application device 8 such that when the veneer pieces 2 and 3 and their teeth 4 are brought together, about half of the flanks of the teeth 4, starting from their tip 4a, are wetted with glue are, as indicated in Fig. 4.
  • this joining area is pressed against the application surface 7 and is preferably heated in the process. This heating takes place in the exemplary embodiment on the top 10 of the veneer pieces 2 and 3 facing away from the glue application surface 7, ie the application plate 11 having the glue application surface 7 is unheated so as not to cause the glue strip 6 to harden prematurely.
  • the glue-receiving application surface 7 is flat and above this flat application surface 7 can be seen as the upper limit of the sliding path of the veneer pieces 2 and 3, the aforementioned guide, which in the exemplary embodiment is designed as a press beam 12 and after the collision of the veneer strips can be moved downwards and can be pressed on .
  • the glue application device 8 which also belongs to the device for gluing toothed abutting edges 1 of veneer pieces 2 and 3 to be connected, for wetting a region of the flat application surface 7 with glue has already been mentioned.
  • the upper limit and guide that is to say the press beam 12, can be moved away from the area of the glue application plate 11, so that the glue application device 8 can be moved into the area of the application surface 7 and can be guided over it. It can be used as an application nozzle, application roller or wheel or the like. be trained.
  • the press beam 12 contains heaters 13, with which he and thus the joining area of the veneer pieces 2 and 3 can be heated in order to reduce the curing time of the glue after assembly and so the cycle time of the method and also to increase the device.
  • the pressure beam 12 according to FIG. 3 has a distance from the glue application plate 11 which is preferably adjustable to the thickness of the veneer strips or veneer pieces 2 and 3 to be glued, by means of which the merging does not hinder, but does climb over each other and sliding the two veneer pieces 2 and 3 is excluded. Due to the adjustability of this distance, veneer strips of different thicknesses can be taken into account. 3 shows at the same time that the thickness of the glue strip 6 is also approximately the thickness of the veneer strips was chosen accordingly.
  • the glue application device 8 in the exemplary embodiment can be moved over the center of the application plate 11, which is made in particular of metal, arranged transversely to the direction of movement of the veneer pieces 2 and 3, and in the middle section thereof a fraction of the width B of the application surface 7 applied so that 2 u for both pieces of veneer. 3 approximately the same sliding path is available and has to be covered and, according to FIG. 4, both veneer strips are each wetted on the front halves of their teeth 4 with approximately the same amount of glue.
  • the two strip-shaped veneer pieces 2 and 3 are only partially shown and partially broken away, whereby the glue strip 6 can be seen again in its original form in the broken-off area, from which it becomes clear how this glue strip through the from both sides in it penetrating teeth 4 of the veneer pieces 2 and 3 is distributed on the flanks.
  • the application plate 11 relative to the glue application device 8 transversely to the direction of movement of the veneer pieces 2 u. 3 is movable to apply the metered glue strip on this application plate 11.
  • the in the direction of movement of the veneer pieces or strips 2 u. 3 when the width of the guide or of the press beam 12 is pushed together corresponds to at least about a quarter, possibly also a third to half of the length of the teeth 4 which are provided and can be pushed into one another on the veneer pieces, the guide surface of the guide facing the veneer pieces of this guide or Press bar 12 parallel to the application surface 7, so it is also flat.
  • this width of the press beam 12 even corresponds approximately to the entire length of these teeth 4 or slightly exceeds them, so that good compression is possible at least in the pushed-together position.
