Title: A Stuart Caunce: Innovator in Thermoplastic Engineering
Introduction
A Stuart Caunce is a notable inventor based in Scarborough, Canada. He has made significant contributions to the field of thermoplastic engineering, holding a total of 2 patents. His innovative methods have improved the functionality and durability of various products, particularly in the escalator and conveyor belt industries.
Latest Patents
One of his latest patents is a method of splicing thermoplastic articles. This invention provides a method and apparatus for forming a joint in elongate articles made from thermoplastic materials, such as escalator handrails and conveyor belts. The process involves holding the end parts of the article in a mold, heating them to remelt the material, and chilling adjacent portions to prevent remelting. The molten end parts fuse together, and the joint is then cooled to resolidify the material. This method allows for the incorporation of reinforcing cables in an interlace pattern, enhancing the structural integrity of the article.
Another significant patent by Caunce is for an improved handrail construction for escalators and moving walkways. Traditional handrails often have a C-shaped cross-section with a stretch inhibitor for dimensional stability. Caunce's improvement includes two spaced-apart plies of reinforcing woven fabric, oriented to have stiff principal yarns extending perpendicular to the stretch inhibitor. This design enhances lateral stiffness, dimensional stability, and lip strength, resulting in a more durable handrail.
Career Highlights
Throughout his career, A Stuart Caunce has worked with various companies, including the Escalator Handrail Company. His expertise in thermoplastic materials has positioned him as a key figure in the development of innovative solutions for the industry.
