  • Patent number: 6565660
    Abstract: The applicator device (AV) for hot-melt adhesive (HK) comprises a housing (1) with an adhesive feeder element (2) and an adjustable nozzle slot (3) to let out the adhesive by pressure. The nozzle slot (3) can be adjusted by means of two nozzle sliders (4) that can be displaced linearly and continuously towards each other from a zero position to a maximum open position with the purpose of adjusting the width (B) of the adhesive applicator. Both sliders (4) are displaced synchronously or independently towards each other, whereby both sliders (4) can be displaced towards each other by the same distance and/or by a different distance from the center (0) of the application width (B) of the nozzle slot (3).
