Application device for a viscous adhesive having a rotatable nozzle

An application device for a viscous adhesive comprising:

• a base body having a first inlet for a viscous adhesive;
• and
• a nozzle body which is rotatable about an axis with respect to the base body and which surrounds a portion of the base body radially on the outside with respect to the axis;
• wherein the nozzle body has a nozzle channel which has a nozzle opening at a first end for discharging the adhesive from the application device and an inflow entry at a second end;
• wherein the nozzle body and the base body are aligned in such a way that adhesive can be conveyed into the inflow entry of the nozzle channel via an orifice of the first inlet;
• wherein a first dynamic seal covers the base body, which rests with an inner side against an outer wall of the base body and with an outer side against an inner wall of the nozzle body;
• wherein a separating agent chamber is formed which surrounds the base body in the circumferential direction and which is delimited radially inside by the outer wall of the base body and radially outside by the inner wall of the nozzle body;
• wherein a second inlet for a separating agent is formed in the base body, which is fluidically connected to the separating agent chamber for feeding the separating agent;
• wherein the first dynamic seal is formed in the direction of the axis between the separating agent chamber and the inflow entry of the nozzle channel of the nozzle body;
• and
• wherein an outlet is formed in the base body and is in fluid communication with the separating agent chamber.
