BENDING DEVICE FOR SHAPING GLASS FOR USE IN AIRCRAFT TRANSPARENCIES

摘要

A sheet bending device includes a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position. A retention member limits movement of a sheet to be shaped relative to the stationary shaping rail portion when the articulating shaping rail portion moves to the shaping position. A “cut-to-size” method is also disclosed to shape a sheet for use in making an aircraft transparency.

主权项

1. A sheet bending device comprising:
a support member; a sheet shaping rail comprising a stationary shaping rail portion securely mounted on the support member and an articulating shaping rail portion pivotally mounted on the support member; a force biasing member operative connected to the articulating shaping rail portion to move the articulating shaping rail portion from a non-shaping position to a shaping position, and a retention member to limit movement of a sheet to be shaped relative to the stationary shaping rail portion when the force biasing member moves the articulating shaping rail portion from the non-shaping position to the shaping position.
