Title: The Innovations of Edward J Winiarski

Introduction

Edward J Winiarski is a notable inventor based in Pawtucket, Rhode Island. He holds three patents that showcase his contributions to the field of engineering and manufacturing. His work primarily focuses on advancements in pelletizing technology, which has significant implications for the production of thermoplastic materials.

Latest Patents

Winiarski's latest patents include a pelletizing apparatus that features a knife adjustment system. This system incorporates a normally non-rotatable quill that is threadably attached to a hub, which extends outward from the face of an extrusion die. This design ensures that the operating temperatures of the quill and hub at the connection location are generally equal. The adjustment means allows for threadably rotating the quill with respect to the hub, thereby adjusting the spacing of cutter knives relative to the die face. This is achieved through a planetary gear system located at the end of the hub that is distal from the die face. The knives are fixed to a knife carrier, which is supported for rotation about the quill.

Another significant patent is the method of cooling pellets. This patent describes a pellet cooling system that includes a novel coolant cage construction. The system ensures the cooling of warm thermoplastic pellets as they emerge from a die head and are cut by rotating knives. The cooling process involves entrainment in coolant flows that are directed peripherally about the cage sides and radially across the front face. After cooling, the pellets are immediately withdrawn from the cage. A unique feature of the coolant cage is the provision of a novel slinger that distributes the coolant flow evenly over its front face.
