Title: The Innovations of Carl S. Weisner: A Pioneer in Thermoplastic Technology

Introduction

Carl S. Weisner, an accomplished inventor based in Pleasant Hill, California, has made significant contributions to the field of thermoplastic technology. With a total of two patents to his name, Weisner has demonstrated a remarkable ability to develop innovative solutions for manufacturing processes in the polymer industry.

Latest Patents

Weisner's latest patents showcase his expertise in extruding polymers to create advanced materials. His first patent, titled "Multicomponent Continuous Film Die," introduces an elongated flat die designed for extruding parallel streams of different polymers. This innovative die includes a body member that houses a replaceable insert, characterized by grooves on its surfaces that define separate passages for the flowing polymers. This technology allows for the production of a continuous, striped film by enabling the different polymer streams to merge in an alternating arrangement before exiting through a variable lip passage.

The second patent, "Method for Extruding Slitting and Fibrillating Thermoplastic Film Tapes," presents a novel approach to film extrusion-fibrillation and narrow slitting processes. This method allows for the production of fibrillated or narrow-width thermoplastic tapes by separating the extrusion-orientation and slitting or fibrillation stages into distinct operations. This not only minimizes disruptions caused by film defects and breakage but also incorporates modifications for heat treatment and film shrinkage, further enhancing the efficiency of the process. These fibrillated tapes can be transformed into cordage products, while the narrow-width tapes serve as critical materials for carpet backing and indoor-outdoor carpets.
