Nozzle arrangement for an edge-strip application device, for exposing an adhesive free, heat-activatable edge strip or workpiece or an edge strip or workpiece which is coated with hotmelt adhesive to hot gas, and edge-strip application device having a nozzle arrangement

摘要

The invention relates to nozzle arrangement (1) for edge strip applying device for supplying hot air to an edge strip (2) which is adhesive-free and heat activateable, with nozzle body (3) with air inlet channel (20, 21) connectable to hot air generator to feed pressurized hot air to nozzle body (3), at least two groups (4a, 4b, 4c) of air outlet openings (40), wherein the air outlet openings (40) are formed on air outlet surface (30) of nozzle body (3) at distance from one another in vertical direction, the outlet surface facing edge strip (2), and fluidically connected to at least one air inlet channel (20, 21) such that two groups (4a, 4b, 4c) are spaced from one another in advancing direction of edge strip (2) and hot air fed to the nozzle body (3) discharges out of the air openings (4) and supplied to edge strip (2) functional layer.

主权项

1. A nozzle arrangement (1) for an edge-strip application device, for exposing an adhesive-free, heat-activatable edge strip (2) or workpiece or an edge strip (2) or workpiece that is coated with hotmelt adhesive to hot air, comprising a nozzle body (3) having
at least one air-inlet duct (20, 21) which is connectable to a hot-air generator such that pressurized hot air can be fed to the nozzle body (3) during operation of the edge-strip application device, at least two groups (4a, 4b, 4c) of air-outlet openings (40), wherein the air-outlet openings (40) are configured in a manner spaced apart from one another in the vertical direction on an air-outlet surface (30), facing the edge strip (2), of the nozzle body (3) and are connected in terms of flow to the at least one air-inlet duct (20, 21) such that the at least two groups (4a, 4b, 4c) of air-outlet openings (40) are spaced apart from one another in the advancing direction of the edge strip (2) and, the hot air fed to the nozzle body (3) can flow out of the air-outlet openings (40) and can be exposed to a heat-activatable functional layer of the edge strip (2), a number of closure members (6, 6′) that corresponds to the number of groups (4a, 4b, 4c) of air-outlet openings (40), said closure members (6, 6′) being configured such that at least some of the air-outlet openings (40) can be selectively opened or closed depending on the width of the fed edge strip (2).
