Method and apparatus for applying a material to a web

This invention relates to the treatment of substrates such as paper with material in repetitive patterns. The substrate web (2) passes beneath an applicator (8) in which orifices for discharging the material onto the web are moved along a path crossing that of the moving web preferably at an angle....

Beschreibung
Zusammenfassung:	This invention relates to the treatment of substrates such as paper with material in repetitive patterns. The substrate web (2) passes beneath an applicator (8) in which orifices for discharging the material onto the web are moved along a path crossing that of the moving web preferably at an angle. The orifices may be formed in an endless belt (9) the lower traverse (28) of which constitutes the floor of a container (23) for the material. The treatment patterns made with this invention can be altered by changing apparatus operating parameters.
