Method of making a landscape blanket

The method of making a landscape blanket having a layer of particles encapsulated between two sheets of flexible resin material, comprising the steps of;

• coating a plurality of stone particles of irregular and non-symmetrical shape and size with an aqueous dispersion containing particles of the same material forming said resin sheets, spreading the coated stone particles on a surface of a single random layer with adjacent stone particles contacting each other and covering substantially all of a given area to form a continuous irregular surface, heating said stone particles to a temperature sufficient to heat the resin film so that the film may be pressed into conforming relationship with said stone particles, conveying said particles in a given path, positioning said resin sheets proximate to each side of said layer of coated stone particles as said layer leaves the end of said path, applying a resilient pressure member to each of said resin sheets to press said resin sheets toward each other at the opposite sides of said layer of stone particles and into contacting and adhering relationship with the irregular surfaces of said heated stone particles at the opposite sides thereof, said aqueous dispersion forming a bond between said resin sheets and said particles, and then cooling said blanket of stone particles and resin sheets after the blanket leaves the pressure members.
