With a total of six patents to his name, MacBean has developed innovative solutions that enhance the efficiency and performance of paper production processes.

Latest Patents: Among his notable inventions are two recent patents. The first is the "Woven Pin Seam in Fabric and Method," which pertains to a woven all-synthetic monofilament dryer fabric designed for use in paper-making machines. This innovative fabric is constructed from a belt woven with warp and weft strands, where the warp strands extend in the machine direction. It features an endless belt interconnected at its ends by a woven single pintle pin seam. The design includes flattened strands in at least some rewoven end portions, providing enhanced functionality.

The second patent, "Three-Layer Forming Fabric," introduces a novel single ply forming fabric intended for twin wire paper-making machines. In this invention, a flat jet stream of pulp is injected between an inner conveying fabric and an outer backing fabric that converge to apply opposing pressure, effectively removing water and forming a sheet of pulp. The outer backing fabric is interwoven with a plurality of monofilament polymeric warp strands, achieving approximately 100% warp fill. This design enhances stiffness in the cross-machine direction, allowing for a more efficient redistribution of pulp widthwise.
