Application head for viscous media, particularly hot melt adhesive, has outlet nozzle and piston cylinder unit, where piston surface has longitudinal extension in direction of longitudinal axis

摘要

The application head has an outlet nozzle (5) for the viscous media and a piston cylinder unit (2) for opening and closing the outlet nozzle. The piston cylinder unit has a piston (6) with piston surfaces (8,9). The piston is movable within the cylinder of the piston cylinder unit along a vertical axis (H). The piston surface has a longitudinal extension in the direction of a longitudinal axis (L), which is larger than a width extension in the direction of a transverse axis (Q) arranged transverse to longitudinal axis. An independent claim is included for an application device with a supply beam.
