Title: Innovations of Robert J DiLullo
Introduction
Robert J DiLullo is a notable inventor based in Paoli, PA (US), recognized for his contributions to the field of nonwoven fibrous articles and thermoplastic materials. With a total of 4 patents to his name, DiLullo has made significant advancements in manufacturing processes that enhance product performance and efficiency.
Latest Patents
One of DiLullo's latest patents focuses on the production of nonwoven fibrous articles. This innovation involves creating superabsorbent articles from aqueous fiber-forming polymer solutions. The process includes forming the polymer into water-soluble filaments, which are then subjected to a primary air stream to attenuate and partially dry them. Following this, a secondary air stream fragments the filaments into fibers, which are collected in a web-forming zone and cured to achieve a water-insoluble state. The meticulous control of temperature and air stream velocities ensures that the fibers are collected without sticking, enhancing the overall quality of the product.
Another significant patent by DiLullo is a multi-bladed disc cutter designed for underwater pelletizers. This cutter is engineered to cut thermoplastic material extruded from a die plate, featuring blades that are integrally formed on the periphery of a backplate. The design includes shroud members that provide added strength against bending and twisting, while perforations allow water to cool and flush away the cut pellets. This innovative approach not only improves the cutter's efficiency but also allows for greater cutting edge capacity compared to traditional designs.
