ABSTRACT:
Stencilling apparatus for applying successive coatings to traveling web stock. The web stock may be advanced in successive wraparound turns to the same stencilling station. The adjacent turns are stencilled simultaneously at this station by a multipart squeegee in a multipart stencil frame, after each is placed in registry. The web tension in each turn of web stock is independently controlled by a pressure differential controller that retains a variable length loop of web under tension by a dynamic air flow pressure differential, which also causes a drying action of any coating on the web.
