<p>387,392. Cutting wired glass. PILKINGTON BROS., Ltd., 631, Tower Building, Water Street, Liverpool, and SMITH, H., 7, Poplar Grove, St. Helens, Lancashire. Aug. 6, 1931, No. 22288. [Class. 56.] A method of breaking-off lengths of wired glass from a continuous strip consists in scoring and snapping the strip, and then applying in the plane of the strip a bending-moment about one end of the cut in order to tear the reinforcing wires. In the construction shown, the glass strip 1 travels over a bed of rollers 2 on to a cutting table 3. The glass is scored transversely by any suitable device, or by a tool guided by a square 4, and it is snapped along the scored line 5 by lifting it from the table by means of a roller 6 which can be raised by a lever 9. A block 10 is fixed to the table 3 in such a position that the glass strip travels in contact with it, and when the cut in the glass reaches the forward corner of the block, the wire netting is torn by pressure applied to the other edge of the strip at the point 12. According to the Provisional Specification, the glass may be scored and snapped by the method described in Specification 378,517.</p> |
