Abstract:
1. A method for separating a glass substrate, the method comprising: conveying a continuous scored glass ribbon on a conveyance pathway in a conveyance direction; directing the continuous scored glass ribbon between a first separation cam and a second separation cam positioned downstream of the first separation cam in the conveyance direction, wherein the first separation cam and the second separation cam are on opposite sides of a centerline of the conveyance pathway and the first separation cam and the second separation cam are non-circular-symmetric about their respective axes of rotation; rotating the first separation cam such that at least a portion of a contact face of the first separation cam is periodically positioned across the centerline of the conveyance pathway and the contact face of the first separation cam periodically contacts a first surface of the continuous scored glass ribbon and displaces at least a portion of the continuous scored glass ribbon from the centerline of the conveyance pathway in a first displacement direction; rotating the second separation cam simultaneously with the first separation cam such that at least a portion of a contact face of the second separation cam is periodically positioned across a centerline of the conveyance pathway and the contact face of the second separation cam periodically contacts a second surface of the continuous scored glass ribbon and displaces at least a portion of the continuous scored glass ribbon from the centerline of the conveyance pathway in a second displacement direction opposite the first displacement direction; and wherein a simultaneous displacement of the continuous scored glass ribbon in the first displacement direction and the second displacement direction separates the continuous scored glass ribbon along a vent of the continuous scored glass ribbon.
