DEVICE FOR BENDING SHEET GLASS Russian patent published in 2013 - IPC C03B23/23 

FIELD: process engineering.

SUBSTANCE: proposed device comprises shaped convex mould 1 accommodating glass workpiece 2 and bending mechanism. Said mould is placed in electric furnace 3 with sight holes. Light beam generator and photo receiver are arranged opposite said sight holes. Said photo receiver is electrically connected with mechanism displacing the stops through actuator relay. Bending mechanism comprises pressure frame composed of two profiled plates 8 boned by flexible tapes t. Bending mechanism drive is composed of driven shaft 9 arranged under mould and coupled with pressure frame edges by flexible members 11. Bending device additionally comprises two support elements composed of plates 13 in contact with glass workpiece bottom surface opposite profiled plates 8 and four stops 14 connected with plates edges to displace said plates to electric furnace bottom by stop drive.

EFFECT: ruled out glass workpiece rupture.
