Equipment for insertion of objects into smoking articles

Apparatus incorporating a filter tow processing unit adapted to supply filter tow to a continuous rod forming unit includes an object insertion unit that positions objects within the filter tow to manufacture a filter rod containing objects positioned at predetermined intervals. The apparatus also includes an upper hopper that acts as a reservoir for a plurality of objects, and provides for supply of objects to a lower hopper. The lower hopper is shaped so that objects are stacked therein. The bottom of the lower hopper is shaped so as to cooperate with a portion of upper region of a rotating wheel. The peripheral face of the rotating wheel incorporates a plurality of spaced pockets, each pocket being of sufficient shape and size to accommodate one object. Objects within the lower hopper are aligned in a single line along a portion of the peripheral face in the upper region of the rotating wheel. Each object then is positioned at predetermined intervals within a continuous supply of filter material. Then, the filter material is formed into a continuous rod having individual objects positioned at predetermined spaced intervals within that rod. The continuous rod then is subdivided at predetermined intervals so as to form a plurality of filter rods (e.g., four-up filter rods containing four spaced objects).

Multi-directional and variably expanded sheet material surfaces

Expandable surfaces made from sheet materials with slits distributed on the surface of sheet material where the surfaces expand by application of force along or/and across the surface of sheet material. The unexpanded surfaces are flat sheets, or closed surfaces like cylinders, spheres, tubes, or custom-designed organic shapes marked with pre-formed or post-formed slit designs. The expanded surfaces can be single units or modules which can be attached to one another through various means. The sheet materials range from hard surfaces like metals, to softer materials like papers and plastics, or pliable materials like fabrics, rubbers, synthetic surfaces or bio-surfaces. The slits are arranged in patterns ranging from periodic, non-periodic to irregular designs. The slits can be straight, bent, curved or irregularly shaped with even or uneven spacing. Slitting can be achieved by digital cutting or punching devices like laser-cutting, water-jet cutting, digital punching, automated dies, etc. or pre-formed when casting the sheet material. Force can be applied manually with tools or through the use of machines and special set-ups. Applications range from architectural surfaces, walls, ceilings, panel systems, structures and sculpture. On a smaller scale, applications include containers, packaging material, fabrics and human wear. On micro- to nano-scale, applications range from expandable surfaces for gauzes, band-aids, stent designs, skin grafts, semi-permeable membranes and micro-filters for various industries including purification of fluids and chemical substances.
