Abstract:
Provided is a dispenser for dispensing particles onto a surface comprising a hopper for receiving particles, wherein the hopper has an opening at its bottom, a screen having openings and located adjacent the opening of the hopper, wherein the screen openings are uniformly sized and spaced and are sufficiently large to let the largest particles pass through during dispensing yet sufficiently small to hold the particles back when the dispenser is not operating, and means, located outside of the hopper, for moving particles from the hopper through the screen, and onto the surface. Also provided is a method of making a web with embedded particles comprising the sequential steps of making the web receptive to the particles by heating, eliminating static charges present on the web, dispensing the particles onto the web, dispersing the particles to minimize particle clumping in the web, and embedding the dispensed particles in the web.
