Abstract

247,862. Golby, F. W., (Libbey-Owens Sheet Glass Co.). Sept. 23, 1925. Drawing.-Relates to sheet-drawing apparatus of the Colburn type, as described in Specification 114,977, and consists in applying drawing-forces to the sheet edges at a series of spaced points and at successively greater drawing-speeds as the sheet is drawn away from its source. The sheet 1 is drawn upwards from a mass of glass 2 towards a bending-roll 4, and each of its edges is gripped near its source by a pair of rollers 7. These rollers are driven at a slower peripheral speed than the speed of the sheet in order to maintain the width of the sheet. In accordance with the invention, a second pair of rollers, 9, is arranged to grip each edge of the sheet at a point between the first pair and the bending-roll, and they are driven at a peripheral speed between that of the first pair, 7, and that of the bending- roll. Due to the additional stretching-force applied by the rolls 9, the narrowing of the sheet which usually takes place between the rolls 7 and the bending-roll, and also the tendency to form surface inequalities, is reduced. The rollers 7, 9 need not be cylindrical but may be shaped to form a thicker edge or bead on the sheet.
