Patent ID: 6881443

Claim:
Adhesive application station ( 14 ) for binding stacked printed products ( 10 ) by means of a liquid or liquefiable adhesive ( 52 ), where the application station ( 14 ) comprises an adhesive discharge system ( 15 ) comprising: (1) an application head ( 12 ) for the adhesive ( 52 ) with a slip surface ( 16 ) for the printed products ( 10 ), and an application nozzle ( 42 ) extending over the entire width (g) of the slip surface ( 16 ) with at least one outlet opening ( 20 ) for the adhesive; (2) an adhesive reservoir ( 50 ); and (3) means ( 54 , 56 , 58 , 64 ) for generating a pressure in the adhesion reservoir ( 50 ) for adhesive application, the improvement comprising: the adhesive discharge system ( 15 ) further comprises, immediately adjacent to the outlet opening ( 20 ), a metering device ( 44 , 45 ) which can be sealed by an actuator ( 130 ) and which, with the adhesive reservoir ( 50 ) formed as a pressure chamber and an integral accumulator ( 54 ), forms a pressure compensation system, where the means for generating the pressure in the adhesive reservoir ( 50 ) is formed inside the accumulator ( 54 ) and arranged proximate the application head ( 12 ), whereby after each adhesive discharge an automatic pressure compensation is guaranteed, wherein the metering device ( 44 , 45 ) is formed as a longitudinally movable metering body ( 45 ) and has several longitudinal channels ( 134 ), and the outlet openings ( 20 ) are formed as slots interrupted by webs ( 136 ).
