    • A particle sprayer includes a particle source, a particle distribution system in hydraulic communication with the particle source, and a spray outlet coupled to the particle distribution system for spraying particles from the particle source, where the particles include discrete fastening bits having one or more projections, with each projection having an overhanging head for snagging fibers. The particle distribution system includes at least one of 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, and a valve in hydraulic communication with the particle source for dispensing particles from the particle source. The particle sprayer may be used to spray fastening bits onto a surface, to turn the surface into a touch fastener.
    • 颗粒喷雾器包括颗粒源,与颗粒源液压连通的颗粒分配系统,以及与颗粒分布系统相连的喷雾出口,用于喷射颗粒源的颗粒,其中颗粒包括离散的紧固钻头,其具有一个或多个突起 每个突起具有用于阻止纤维的悬伸头。 颗粒分配系统包括从加压流体入口延伸到喷雾出口的导管中的至少一个,并且构造成限制载体流体的流动沿着导管朝向喷雾出口流动,以推动颗粒从颗粒源远离喷雾 出口,以及与颗粒源液压连通的阀,用于从颗粒源分配颗粒。 颗粒喷雾器可用于将紧固钻头喷射到表面上,以将表面转变成接触紧固件。
