ABSTRACT:
In the process for the production of a glued joint for wood, the surfaces to be glued are held tightly together. At least one injection needle is driven into the wood up to a depth at which the outlet of the needle point comes into contact with the surface. The fluid adhesive is then driven under pressure through the injection needle and evenly distributed between the surfaces. The process is particularly suited for the production of window blind frames made of wood, in which the wood edges to be glued are joined by means of pins and slots. The process makes possible the production of joints of great strength, with very low tolerances between the pins and slots.
