Title: Joseph Chabal: Innovator in Glass Plastic Assemblies
Introduction
Joseph Chabal is a notable inventor based in Gibsonia, PA (US). He has made significant contributions to the field of glass plastic assemblies, holding a total of 3 patents. His innovative methods and apparatuses have advanced the technology used in laminated windshields and other applications.
Latest Patents
One of Joseph Chabal's latest patents is for a method of prepressing glass plastic assemblies. This method involves preliminarily pressing a bent assembly that consists of a pair of bent glass sheets and a flexible interlayer. The process includes a first heating step performed without vacuum, followed by a biasing step, an unbiasing step, and a second heating step that is conducted simultaneously with the application of vacuum. This prepressing technique results in fewer bubbles after a heat stability test, compared to assemblies that undergo a different prepressing method.
Another significant patent by Chabal is for an apparatus designed for differentially stretching, aligning, and cutting sheet materials. This invention allows for the differential stretching of plastic with a dyed border, which is suitable for shaded interlayers of laminated windshields. The apparatus ensures that the arcuately shaped web of plastic is realigned between cutting operations, maintaining the proper angle and orientation for effective cutting.
