1. A method, comprising:
depositing a hot flexible glass-containing ribbon along a plurality of sequentially conveyed molds;
rolling a pressure roller over a surface of the glass-containing ribbon, such that at least one pinch region is actuated in the glass-containing ribbon as the glass-containing ribbon is pinched between a protruding pinch edge of the pressure roller and a surface of the mold, wherein the at least one pinch region has a cross-sectional thickness that is not greater than 75% of a cross-sectional thickness of the glass-containing ribbon;
cooling the glass-containing ribbon; and
separating the glass-containing ribbon along the at least one pinch region into discrete glass parts.
