ABSTRACT:
Extrudable materials which exhibit a decrease in viscosity as the shear rate is increased, such as magnetic dispersion striping materials, are extrusion coated in the form of a narrow stripe. The stripe has predetermined uniform cross-sectional dimensions including substantially uniform thickness, and is coated onto a moving web by means of a die maintained in a predetermined spaced relation with the web. The die has two or more bores through which the extrudable material is extruded in columns onto the moving web to form the stripe thereon.
