摘要： A corner (2A,2B) of a glass sheet (2) is ground and polished using a grinding wheel (35) and a polishing wheel (36) which can be selectively activated and are carried by the same motor-driven drive shaft (33) and by displacing, by means of two movement devices (13) (14), the motor-driven drive shaft (33) along two directions (6) (21) which are transverse with respect to each other; in each movement device, the motor-driven shaft (33) is displaced by an electric motor when the grinding wheel (35) is selected and by a corresponding pneumatic actuator when the polishing wheel (36) is selected.

摘要： A succession (8) of glass sheets (2) is fed in a longitudinal direction (6A) at a predetermined speed and through a grinding station (13), in which a perimeter surface (5) of the glass sheets (2) is first ground by means of one or more grinding wheels (22) and then polished by means of one or more polishing wheels (27); during the grinding and the polishing, the current absorbed by each of the electric motors (23)(28) rotating the wheels (22)(27) is detected, compared with a corresponding predetermined limit value of current that can be absorbed by the electric motor (23)(28) and, when above this, continuing to feed the succession (8) of glass sheets (2) in the longitudinal direction (6A), reducing at least one of either the relative sheet-wheel speed and the thrust action of the polishing wheels (27) against the glass sheet (2) being processed.

摘要： A succession (7) of glass sheets (2) arranged at a predetermined distance (D) from each other is fed along a longitudinal direction (12) and through a grinding station (13), in which a peripheral surface (5) of the glass sheets (2) is progressively ground through a row (A) of grinding wheels (22) arranged side-by-side in a direction parallel to the longitudinal direction (12); during the grinding of the sheets (2) the wear of at least one first grinding wheel (22') is detected and the same first grinding wheel (22') is repositioned, keeping the succession (7) of sheets moving through the grinding station (13) and in a time period ranging between the moment in which a tail of a sheet (2') being ground on the first grinding wheel (22') has left the first grinding wheel (22') and before a head of a consecutive sheet (2') to be ground reaches the first grinding wheel (22').

摘要： A sheet (2) of laminated glass, having two outer sheets of glass (3,4) and an intermediate layer (5) of synthetic material, is cut by forming a score line in both the outer sheets (3,4) of glass; breaking, by flexing, the outer sheets (3,4) of glass into two sheet portions (1a,1b) joined by the intermediate layer (5) of material; heating the intermediate layer of material between the sheet portions by means of a heat source (37); and cutting the intermediate layer of material to separate the sheet portions; scoring at least one (3) of the outer sheets of glass (3,4) , and breaking of the same outer sheet (3) of glass being performed simultaneously.
Furthermore actuating means comprising guide means are disclosed for guiding the heat source along a sloping plane forming a given angle with a supporting surface for the laminated glass sheet.
