Glass separation systems and glass manufacturing apparatuses comprising the same

An apparatus for forming a glass substrate from a glass ribbon, the apparatus comprising:

• a forming vessel comprising a first forming surface and a second forming surface converging at a root;
• a glass conveyance pathway extending from the root in a downward vertical direction;
• a glass separation system positioned downstream of the forming vessel and comprising:
• an A-surface nosing bar positioned on a first side of the glass conveyance pathway, the A-surface nosing bar comprising a first A-surface nosing actuator coupled to a first end of the A-surface nosing bar and a second A-surface nosing actuator coupled to a second end of the A-surface nosing bar;
• a B-surface nosing bar positioned on a second side of the glass conveyance pathway and opposite the A-surface nosing bar, the B-surface nosing bar comprising a first B-surface nosing actuator coupled to a first end of the B-surface nosing bar, and a second B-surface nosing actuator coupled to a second end of the B-surface nosing bar;
• a scoring apparatus positioned on a first side of the glass conveyance pathway downstream from the A-surface nosing bar, wherein:
• the first end of the A-surface nosing bar is opposite the first end of the B-surface nosing bar and the second end of the A-surface nosing bar is opposite the second end of the B-surface nosing bar;
• and
• the glass separation system comprises a clamping mode and an adjustment mode wherein, in the adjustment mode, an actuation stroke length of the first A-surface nosing actuator and an actuation stroke length of the second A-surface nosing actuator are independent of one another and an actuation stroke length of the first B-surface nosing actuator and an actuation stroke length of the second B-surface nosing actuator are independent of one another.

A method of separating a glass sheet from a glass ribbon, the method comprising:

• conveying a continuous glass ribbon in a conveyance direction on a glass conveyance pathway, wherein the glass conveyance pathway extends through a glass separation system comprising an A-surface nosing bar positioned on a first side of the glass conveyance pathway and a B-surface nosing bar positioned on a second side of the glass conveyance pathway;
• pivoting the A-surface nosing bar about an A-surface axis of rotation and the B-surface nosing bar about an B-surface axis of rotation such that, after the pivoting, the A-surface nosing bar and the B-surface nosing bar are parallel with the major surfaces of the continuous glass ribbon;
• advancing the A-surface nosing bar and the B-surface nosing bar towards the continuous glass ribbon such that the continuous glass ribbon is clamped between the A-surface nosing bar and the B-surface nosing bar;
• forming a score line in the continuous glass ribbon;
• and
• separating a glass sheet from the continuous glass ribbon at the score line.
