Abstract: A nozzle device (2) is disclosed for spraying a fluid material, such as a hotmelt adhesive and particularly in the form of a kind of glue with a bonding time of fractions of a second, and which is suited for application on a narrow side edge (8) of an item (10), such as application upon a narrow side of a veneer sheet, more specifically on the narrow side edge (8), by edge-to-edge bonding of thin veneer sheets of mainly, though not quite, uniform thickness, as the veneer sheets in the form of lengths for mutual bonding are passed close by such nozzle device, where above and below the nozzle opening (4) there are provided guide members (12, 14), which are capable of supporting the lateral rims of the item (10) moved past the nozzle opening (4) and to be applied the sprayed material. Furthermore, there are described different embodiments and devices for these elements.

Abstract: A method and an apparatus for edge joining of strip shaped plate or sheet elements of veneer (42, 48) by application of a hotmelt glue to at least one of the veneer edges to be joined and then forcing the elements (42, 48) together edge to edge before the glue solidifies, characterized in applying the glue in fully melted condition through heated nozzle means (40, 44) arranged so as to direct the applied glue as a jet or flow directly against a middle area of the relevant edge or edges is described. Preferably, the supporting area (2) for the opposite veneer strip (48) edge is located at a higher level (50) and preferably partly overhead the nozzle (40,44). By means of the described method and apparatus it is achieved that the total edge area of the veneer elements being heated, while gluing, is small, thereby not inducing any drying effect of importance on the veneer elements.
