METHOD AND APPARATUS FOR MAKING A WATER DRAINAGE-PROMOTING WRAP
A method and apparatus for making a water drainage-promoting wrap for applications such as housewrap and roofing underlayment. A substrate, which may be breathable or non-breathable, is conveyed through a nip between a rotating sleeve and a roll, the sleeve having a plurality of apertures therein. A fluid resin composition is fed into the sleeve and is fed out through the apertures in the sleeve as it rotates and as the substrate moves through the nip, forming spaced-apart spacer elements on a face of the substrate. The spacer elements are then dried or cured.
