Abstract
The invention provides an articulated bending mold for shaping heat softened substrates, e.g., glass sheets, into curved shapes. The bending mold has a central portion with at least one, and preferably two, pivoting end sections. A biasing assembly is mounted on the side of the mold between the end section pivot points, preferably outboard of the end section pivot points and in proximity to an outer side of the end section. The biasing assembly includes a weight arm with a linkage assembly mounted on one end of the weight arm and connected to the end section, preferably at or near an outer corner of the end section.
