APPARATUS AND METHOD FOR FLUID ADHESIVE APPLICATION

摘要

This disclosure involves periodically bumping webs such as a cigarette filter paper or the like against a shear surface disposed beyond a multi-nozzle adhesive extruder to provide longitudinally intermittent bands of adhesive coatings for the filters or the like, with optional provision for continuous marginal lines of adhesive along and between the bands for adhesion on the head and tail ends of such filters or other articles as well.
