摘要:
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.
摘要:
An adjustable insulating window is disclosed comprising two glass sheets separated by and bonded to a bonding strand which is positioned inward relative to the peripheral edge surface of each of the glass sheets. A groove is formed along the peripheral edge surface of the window by the bonding strand and the peripheral edge of the two glass sheets, into which groove a profile strip is placed flush with at least one glass sheet and fastened by the bonding strand.
