Abstract
The invention relates to an apparatus for the preferable two-dimensional arching of glass sheets heated to the softening temperature comprising a following cooling section, the horizontal guiding of the glass sheets taking place on a plurality of movable transport rods and rollers which form a horizontal surface. The transport rods are provided in two groups which project outwardly from a respective mounting at the two lateral edges of the roller hearth furnace into the roller hearth furnace surface; the two groups of the transport rods are pivotal by a pivot movement via their respective mountings downwardly between linear forming elements, in particular forming rods, the joint upper tangential surface of which corresponds to the contour of the lower side of the arched glass sheet. Alternatively, at least one edge region of some transport rods may be pivoted upwardly to arch glass sheets or panes having one or two bends, for example bus windows or display case panes.
