Methods of severing a glass ribbon comprises the step of impacting a first side of a glass ribbon with fluid emitting from a support member to at least partially support a weight of a portion of glass ribbon within a severing zone while maintaining the portion of the glass ribbon in a first orientation. The method further includes the step of temporarily bending the portion of the glass ribbon in a direction toward the support member from the first orientation to a severing orientation by applying a force to a second side of the glass ribbon. The method still further includes the step of severing a central portion of the glass ribbon between opposed edge portions at a predetermined flaw located in the severing zone. The method then includes the step of returning the portion of the glass ribbon to the first orientation by removing the force being applied to the second side of the glass ribbon.
