NOZZLE ARRANGEMENT FOR AN EDGE STRIP APPLYING DEVICE FOR SUPPLYING HOT AIR TO AN EDGE STRIP OR WORKPIECE WHICH IS ADHESIVE-FREE AND CAN BE ACTIVATED BY HEAT OR WHICH IS COATED WITH A HOT-MELT ADHESIVE, AND EDGE STRIP APPLYING DEVICE COMPRISING A NOZZLE ARRANGEMENT

摘要

The invention relates to a nozzle arrangement (1) for an edge strip applying device for supplying hot air to an edge strip (2) or workpiece which is adhesive-free and can be activated by heat or which is coated with a hot-melt adhesive, comprising a nozzle body (3) with - at least one air inlet channel (20, 21) which can be connected to a hot air generator such that pressurized hot air can be fed to the nozzle body (3) during the operation of the edge strip applying device, - at least two groups (4a, 4b, 4c) of air outlet openings (40), wherein the air outlet openings (40) are formed on an air outlet surface (30) of the nozzle body (3) at a distance from one another in the vertical direction, said outlet surface facing the edge strip (2), and are fluidically connected to the at least one air inlet channel (20, 21) such that the at least two groups (4a, 4b, 4c) of air outlet openings (40) are spaced from one another in the advancing direction of the edge strip (2) and the hot air fed to the nozzle body (3) can be discharged out of the air outlet openings (40) and supplied to an edge strip (2) functional layer which can be activated by heat, and - a number of closing organs (6, 6') which are designed such that at least some of the air outlet openings (40) can be optionally opened or closed dependent on the width of the fed edge strip (2), said number corresponding to the number of groups (4a, 4b, 4c) of air outlet openings (40).
