An end cap assembly for a conveyor roll includes an end cap configured to fit over an end of the conveyor roll, and the end cap has an opening. The end cap assembly further includes a spring member configured to be positioned between the end of the conveyor roll and the end cap, and a fastener that is insertable into the opening of the end cap. The fastener is configured to cooperate with the spring member to apply a retention force to assist in retaining the end cap on the conveyor roll.

A glass sheet quench station () and method for quenching glass sheets includes quench control valves () that are operated to reduce unnecessary quenching air and thereby provide efficiency in the quenching.

Quench station and method for formed glass sheet quenching

A method having particular utility for making outer and inner formed windshield glass sheets is performed by glass sheet positioning centrally on a forming face () of a forming mold () to form each glass sheet to a design shape regardless of any size difference between the glass sheets from one cycle to the next.

Method for positioning glass sheets for forming

Apparatus ( ) and a method for roll bending heated glass sheets includes a pair of sets of bending rolls ( ) and a support and drive mechanisms ( ) that supports and rotatively drives the bending rolls at progressively increasing inclinations within a heating chamber ( ) of a roll bending station ( ) to provide engagement and bending at opposite lateral sides of a conveyed glass sheet. The bending rolls ( ) are positioned in their progressively inclined inclinations by cooperation of an elongated connector ( ) and clamps ( ) for providing securement to curved support ribs ( ) of an associated frame at the adjacent lateral side of the roll bending station housing.

Apparatus and method for roll bending heated glass sheets

A press bending station ( ) for heated glass sheets includes a lower wheel bed ( ) having a lower support ( ) and wheel assemblies ( ) with detachable connections ( ) to a drive mechanism ( ) of the lower support to provide rotational driving of a wheel ( ) of each wheel assembly. An actuator ( ) provides relative vertical movement that lifts a heated glass sheet received by the wheel bed ( ) to provide press bending thereof between a lower press ring ( ) and an upper press mold ( ). The wheel bed ( ) can have a curved shape or a flat shape. Connection and detachment of the wheel assemblies ( ) facilitates switching from one production job to the next.

Press bending station and method for job switching

A glass sheet quench station ( ) includes first and second quench sections ( and ) that cooperate with a three position shuttle ( ) and a control ( ) to transfer glass sheets through the quench station with partial quenching performed at the first quench station and completion of the quenching at the second quench section. This glass sheet quenching method with two stage quenching shortens the cycle time to provide increased production.
