Abstract
A glass grinding and/or polishing apparatus comprises a chuck which holds a glass to be repaired, and is rotated by means of a drive motor. The chuck is mounted in an arm which is arranged to move in an arcuate path over a substantially flat rotary grinding disc, and subsequently over a secondary grinding station and two polishing stations. During operation, fluid is continually circulated through a sealed enclosure of the apparatus, to flush away particles of glass, etc., which are collected as sediment in a disposable tank.
Claims16
Apparatus for grinding and/or polishing glasses, comprising:
- gripping means arranged to grip a glass;
- at least one grinding means and at least one polishing means arranged to grind and polish the rim of a glass gripped in the gripping means;
- and
- transport means arranged to cause relative movement between the gripping means and the grinding and polishing means;
- wherein the grinding and polishing means each comprises an abrasive member having a resilient and substantially planar working surface disposed at such an angle that, during movement of the gripping means relative to the grinding and polishing means, the rim of a glass gripped in the gripping means travels over each said working surface from a first to a second region thereof, the second region being closer than the first region to the base of the glass.

Apparatus for grinding and/or polishing glasses, comprising:
- gripping means arranged to grip a glass;
- at least one grinding means and at least one polishing means, each arranged to grind and/or polish the rim of a glass gripped in the gripping means;
- and
- transport means arranged to cause relative movement between the gripping means and the grinding and polishing means such that a glass gripped in the gripping means travels successively over the working surface of the or each grinding and polishing means:
- wherein:
- the grinding means and polishing means each comprise a rotary abrasive disc having a substantially planar working surface disposed at such an angle that, during relative movement of the gripping means and the grinding and/or polishing means, the rim of a glass gripped in the gripping means travels over said working surface from a first to a second region thereof, the second region being closer than the first region to the base of the glass;
- and
- the working surface of the or at least one of the grinding and polishing means other than the first grinding means is closer to the base of a glass gripped in the gripping means, than is the working surface of the or each preceding grinding or polishing means.

Apparatus for grinding and/or polishing glasses, comprising:
- gripping means arranged to grip a glass;
- at least one grinding and at least one polishing means arranged to grind and polish the rim of a glass gripped in the gripping means;
- and
- transport means arranged to cause relative movement between the gripping means and each grinding and polishing means such that a glass gripped in the gripping means travels successively over the working surface of each grinding and polishing means, and the working surface of each grinding and polishing means, other than the first grinding means, is closer to the base of a glass being gripped in the gripping means than is the working surface of each preceding grinding and polishing means:
- wherein:
- the grinding and polishing means comprises an abrasive member having a substantially planar working surface disposed at such an angle that, during relative movement of the gripping means and the grinding and polishing means, the rim of a glass gripped in the gripping means travels over said working surface from a first to a second region thereof, the second region being closer than the first region to the base of the glass.

Apparatus for grinding and/or polishing glasses, comprising:
- gripping means arranged to grip a glass;
- grinding and polishing means arranged to grind and polish the rim of a glass gripped in the gripping means and each comprising a disc, the disc of the grinding means being disposed at a first angle to the path of travel of a glass gripped in the gripping means and being provided with a first degree of resilience, and the disc of the polishing means being disposed at a second angle to the path of travel of a glass gripped in the gripping means and being provided with a second degree of resilience, said second angle being greater than said first angle, and said second degree of resilience being greater than said first degree of resilience;
- and
- transport means arranged to cause relative movement between the gripping means and the grinding and polishing means:
- wherein:
- the grinding and polishing means comprises an abrasive member having a substantially planar working surface disposed at such an angle that, during relative movement of the gripping means and the grinding and polishing means, the rim of a glass gripped in the gripping means travels over said working surface from a first to a second region thereof, the second region being closer than the first region to the base of the glass.
