Abstract:

Various embodiments of the present invention provide systems and methods for manufacturing crumb rubber products. In various embodiments, the product being manufactured is a floor mat, which may be a decorative floor mat or fatigue floor mat used in industrial applications. In various embodiments, a crumb rubber and binder mixture is dispensed into a pan and leveled within the pan using a vibratory leveling operation. A die release may then be applied and the pan conveyed into a press. The press may be equipped with an upper die, which is compressed against the crumb rubber in the pan. The press applies both heat and pressure to activate the binder, which bonds the crumb rubber granules together to form a cohesive mat.
