VORRICHTUNG ZUM BERUEHRUNGSLOSEN AUFTRAGEN EINES FLUESSIGKEITSSTREIFENS AUF EINE LAUFENDE MATERIALBAHN

摘要

In a device for contactless application of a strip of liquid, in particular strip of glue (3), onto a running material web (1) with at least one application head (4) which is provided with at least one nozzle (6) which arranged at a distance (a) from the material web (1) and can be activated or deactivated by means of a valve (8) which can be driven as a function of the desired application pattern, a high degree of accuracy can be achieved in that the operating points of the valve (8) can be corrected with respect to the application pattern-dependent basic values by a correction value which can be determined as a function of the speed of the material web (1) and at least the spacing (a) of the web with respect to the nozzle (6). ……
