Title: Innovations of Jeffrey L. Marietti

Introduction

Jeffrey L. Marietti is a notable inventor based in Tarentum, Pennsylvania. He has made significant contributions to the field of glass shaping technology, holding three patents to his name. His work focuses on innovative methods for forming glass sheets into complex shapes while minimizing imperfections.

Latest Patents

One of his latest patents is centered around the pressure forming of glass sheets. This invention discloses a method and apparatus for shaping glass sheets into deeply sagged configurations. The process utilizes a lower outline mold and an upper shaping mold, which work together to minimize marking on the glass sheets. The outline mold features a support rail that corresponds to the desired curvature of the glass sheets. As the sheets are heated, they sag under gravity to achieve a preliminary shape. The molds are then adjusted to either come close together or press against the glass sheets. Pressurized gas is directed from the mold to the unsupported central portions of the preliminarily shaped sheets, urging these areas downward to achieve the desired configuration.
