A sliding support table to support a continuously advancing glass ribbon during severing. The ribbon is supported by and moves over the sliding support table which moves along the direction of the glass ribbon travel between stationary upstream and downstream supports. Top and bottom line heaters supported on the table direct flames towards the major surfaces of the glass ribbon along a line cut. A blade and anvil arrangement supported on the table, sever the glass along the heated line of cut when the line of cut is positioned therebetween. The table advances along with the glass ribbon to support the ribbon during the heating and severing operation. The line heaters and blade and anvil arrangement may provide both a linear or nonlinear line of cut.
