Definitions

  • the invention relates to an applicator head for applying liquid media such as liquefied thermoplastics or molten H exertschmelzklebem on a relatively movable to the applicator head material web, with a housing having a roller chamber in the housing in which a roller slide is rotatably driven, with at least one feed opening for initiation from medium into the roller chamber and with a slot nozzle for discharging medium, which is controllable by the roller slide and extending transversely to the direction of movement of the material web.
  • the application head can be arranged in particular contactless to the material web.
  • An applicator head of the aforementioned type is known from DE 197 14 029 C2 known.
  • a roller slide is used, which in an axial region in which the feed opening is located, has a recess extending over the entire circumference.

  • a nozzle is provided in the housing and an annular channel between the roller slide and roller chamber is formed, which is connected to the nozzle in the housing connected, and that radial feed holes in the roller slide in the plane of Ring channels are executed, which are connected to the inner cavity and serve to supply liquid medium.
  • the mentioned annular channel can be formed by an annular groove in the Wafzenkarnmerober Structure.
  • the annular channel is formed by a circumferential groove in the surface of the roller slide, which is in communication with the supply port in the housing.
