Definitions

  • the invention relates to veneer joining machines, and more specifically to a veneer joining machine for cabinet making and the furniture trade;
  • the object of the invention is to provide a veneer joining machine which operates as far as possible without trouble, is strong and easily adjustable and whose construction is as simple and cheap as possible.
  • the veneer joining machine includes a device for transporting the veneers, pressing together the veneer edges in horizontal direction and sticking adhesive paper strips on the longitudinal edges of the veneer halves running through the machine, said device comprising two positively driven counter-running rotary plate discs arranged side by side in a horizontal plane, and a pressure roller arranged longitudinally centrally between said plate discs in the direction of feed, cooperatively connected with said two plate discs and rotated thereby as the veneers run through the machine, the vertical axis of said pressure roller being arranged in advance in relation to a line passing through the axes line of the two plate discs arranged side by side.
  • Fig. 1 is a fractional side elevational view, on a reduced scale, of a veneer joining machine
  • Fig. 2 is a front elevation of Fig. 1
  • Fig. 3 is a top plan view thereof.
  • the veneer joining machine comprises a machine frame 0 and two plate discs at and b mounted thereon.
  • the two plate discs a and b are arranged close together in a horizontal plane on vertical axles a, b respectively, and are positively driven at the same speed by means of toothed gear wheels or the like, not shown, so that they rotate in opposite directions as indicated by arrows in Fig. 3.
  • a pressure roller c is arranged centrally thereof in the transport direction of veneer halves to be worked, and driven by friction.
  • the pressure roller c is rotatable about an axle s in a depending fork g which, being loaded by a pressure spring h or the like, is movable in a vertical plane, that is up and down.
  • the axle s of the pressure roller c lies in a vertical plane 0 which extends in front of a vertical plane (I in which the axles a and b of the two plate discs a and b are situated.
  • the bearing of the pressure roller c is so constructed that not only the pressure roller can yield in upward direction according to the thickness of the veneers actually to be worked and exert uniform pressure with the aid of springs, weights or the like on the veneers pushed into the machine, but that it can also be adjusted horizontally in the transport or feed direction to bring it in a suitably advanced position in relation to the vertical plane :1 in
  • the reference i designates a thin partition which is known per se and whose object is to allow the veneer halves to lie parallel close together yet prevent them T from sliding one over the other when being pushed into the machine and while they are being carried along.
  • the machine operates in the following manner:
  • the veneer halves After veneer halves e and have been introduced as indicated by the dot-dot-dash lines in the drawings, the veneer halves, at first resting on a table m or the like, are pressed by the pressure roller c on to the two counterrotating plate discs a and b. Owing to the pressure roller c being mounted ahead, the vertical pressure is exerted on the plate discsa and b in front of the vertical plane d,
  • the machine is particularly suitable for gluing together veneer sheets which are not of the same thickness and consequently difiicult to stick.
  • a rocker beam n is arranged below the two plate discs a and b and each one of the vertical axles of the plate discs a and b, has its shaft butt bearing on the adjacent, end of the rocker beam n.
  • one or other of the plate discs a, b sinks to a greater or lesser degree, the position of the two plate discs being however directly compensated by the rocker beam n.
  • the advantages of the veneer joining-machine according to the invention are not only the extremely simple, clear, space-saving arrangement, enabling the machine to be easily cleaned, but also--due to the lack of feeding chains and all elements serving for mounting the same, such as slide tracks, guide rollers and the likea considerable saving in material and a corresponding reduction in the cost of production is attained.
  • the reliable operation of the machine and the extremely careful manner in which the veneer sheets are handled when running through the machine also constitute advantages which are due to the fact that, as compared with the many rollers of the known constructions which press the veneer halves against one another in horizontal direction and consequently very quickly destroy weak and undulated veneers, the pressing together of the veneer halves in horizontal direction is effected by the smooth plate discs allowing at the same time the transport of the veneers, as compared with the link chains hitherto used.
  • a device for feeding veneer stripsfpressing their longitudinal edges together and sticking adhesive paper tapes thereon comprising a pair of counter-running rotary plate discs flying'closely adjacent each other in a common plane and supported on axles, a pressure roller cooperating with said pair of plate discs and driven thereby as the veneer strips pass between said pair of plate discs and said pressure roller, and means associated with said pair of plate discs and allowing adjustment of said plate discs in opposite directions from said common plane in dependency upon each other.
  • said means includes a two-armed lever supporting with each of its arms the axle of one of said plate discs.
