ABSTRACT:
A partial press for shaping heat softened glass sheets as they are supported on a bending mold and conveyed through a lehr includes a press member that contacts selected portions of the glass sheet. The press member moves with the glass sheet so that there is no relative horizontal movement between the press member and the glass sheet as the glass sheet is conveyed through the lehr.
