ABSTRACT:
A process of extrusion coating which is particularly useful in the manufacture of viscous pressure-sensitive adhesive sheets and tapes is described. In the process, the distance between the die orifice and contacting substrate, and spaced coating roll and the relationships between the direction of extrusion, the direction of approach of the substrate and the direction of departure of the coated substrate are important.
