Abstract

The panes are heated to the desired bending temp. and are then fed between an upper row (a) and a lower row (b) of rollers which form a curved gap and bend each pane as it travels between the two row (a, B). During the bending process, a current of air is blown between the rollers to toughen the panes. Each roller in row (a) has a shaft rotating in a bearing on each end of the shaft; and each bearing is mounted on the piston of a pneumatic cylinder (PC) exerting a constant pressure. Similar bearings are used for the lower row (b), but in this case the bearings are mounted via straps on two leaf springs providing a desired curvature in conjunction with the PC used on the upper row (A) of rollers.
