Apparatus and method for moving a glass mass, such as a glass sheet in horizontal attitude through a bending section of a heating oven. The glass sheet at a deformation temperature is imparted movement along the conveyor system including a plurality of rollers, and a gaseous flow at high temperature, having a flow speed which varies continuously across the width of the glass sheet, impinges on its lower surface to at least partially balance the weight of the glass sheet in regions requiring good optical quality.

Method for the transportation of glass sheets brought to the deformation

The invention relates to the manufacture of laminated glass, comprising glass sheets and plastic sheets. In the manufacture, glass and plastic sheets are each cut to a final dimension desired for use in laminated glass, assembled in a preliminary way, and, then, by the action of temperature and pressure formed to the laminate. The cutting of the plastic sheets, is carried out more particularly a plastic sheet of polyvinyl butyral as an interlayer between outer sheets of silicate glass is carried out by a high pressure water jet.

Process for manufacturing laminated glass

Process and apparatus for bending glass plates in horizontal or approximately horizontal position. The invention includes processing the glass plates by means of an installation comprising a glass reheating furnace, a bending station, and a horizontal conveyor for routing the glass plates through the furnace and bending station. A curved surface is placed above the horizontal conveyor in the bending station, and a blower is adapted to deliver a hot air current to bend the glass plates by heating them and applying pressure to urge them against the curved surface to which the desired configuration has been given. Then the glass plates are gently rested on a carrying frame where they continue to be supported, only in part, by said hot air current. The invention makes possible the bending of glass plates individually or, for example, in pairs.
