Title: Yale Karmell: Innovator in Printing Technology

Introduction

Yale Karmell is a notable inventor based in Chicago, IL, recognized for his contributions to printing technology. With a total of 3 patents, Karmell has developed innovative methods and materials that enhance the efficiency and quality of printing operations.

Latest Patents

Karmell's latest patents include a method of making a roll for use in printing. This invention features a tubular mesh sleeve covered with an elastomer composition, such as Buna-N rubber. The composition incorporates discrete fibers, like nylon fibers, which are uniformly dispersed throughout. The sleeve is stretched over a metal mandrel, and the composition is extruded onto the sleeve to create a seamless covering that is vulcanized to the sleeve. After the mandrel is removed, the sleeve with its vulcanized covering is bonded to a metal core using a suitable adhesive, such as epoxy. The outer surface is then ground to raise a nap of the fibers and cleaned to eliminate any foreign matter.

Another significant patent involves a polyurethane-derived plasticizer for polyacrylonitrile printing rolls. This invention presents a new use for the liquid reaction product of a polyurethane and an amine or alkanol amine at elevated temperatures. It serves as a plasticizer for acrylonitrile rubbers, making otherwise incompatible reaction products compatible with the acrylonitrile elastomer. This innovation also includes a printing roller composition that incorporates the reaction product as a plasticizer.
