Abstract
635,022. Grinding and polishing glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. Aug. 7, 1947, No. 21656. Convention date, July 13, 1943. [Class 60] Apparatus for grinding or polishing simultaneously the two faces of a continuous ribbon of moving glass 6 is characterized by the provision of co-axial pairs of upper and lower grinding or polishing tools which are movable as aligned pairs of tools from operative positions to a position at the side of the moving ribbon of glass, and vice versa, in horizontal planes parallel to the surface of the glass. The displacement of the tools may be effected by either a translatory or a rotational movement. The preferred embodiment employs a C-shaped support 1 carrying the rotary tools 9 and 10 driven by motors 11 and 15, respectively. The tool 9 is counterbalanced by a weight 12 and vertically adjusted by a hand wheel 14 or a motor, while the tool 10 is vertically adjusted by a winch 16 manually or motor-operated. The support 1 runs on rails 4 and is driven by a rack and pinion connected with a motor 25, a cover 23 being removed to allow the support to be displaced. A chassis 28 provides support for the glass when the ower tool is withdrawn, and a similar chassis may be provided to prevent lifting of the glass. The level of the glass is indicated by a lever 30 having one end provided with a ball 31 to contact the lower face of the glass while the other end registers with a scale 33. Proper transverse location of the support 1 on replacement after overhaul is ensured by a reference mark. The tools are fed with abrasive material by pipes 18 and 19 while a hopper 20 collects used abrasive which is fed to a pipe 22 by gravity.
