An in-situ applicator for applying a composition in a pipe comprises a flow diverter configured to receive a composition and eject the composition from at least one outlet. The applicator also comprises a hollow conical body having a narrow end, a broad end, and an interior surface configured to receive the composition ejected from the flow diverter. The conical body also has a plurality of holes forming a band that wraps circumferentially around the conical body which defines a flow region on the interior surface between the band and the narrow end. The band includes first holes adjacent to the flow region where each of the first holes has a first average diameter and second holes disposed between the first holes and the broad end, each of the second holes having an average diameter greater than the first diameter.

Apparatus for in-situ pipe coating and related methods

Nonwoven abrasive articles, particularly lofty nonwoven abrasive articles, with a textured, non-planar surface and an abrasive coating thereon. The coating may cover the entire surface or only portions of the surface. The textured surface, composed of peaks or high regions and valleys or recessed regions, provides improved cut performance over nonwoven abrasive articles having a generally planar abrading surface.
