Abstract
A particle sprayer includes a source of discrete particles, a spray outlet coupled to the particle source, and a conduit extending from a pressurized fluid inlet to the spray outlet and configured to constrain a flow of carrier fluid to flow along the conduit toward the spray outlet to propel particles from the particle source away from the spray outlet. The particles including discrete fastening bits having one or more projections, with each projection having an overhanging head for snagging fibers. The particle sprayer may be used to spray fastening bits onto a surface, to turn the surface into a touch fastener.
