Abstract

Apparatus for dividing laminated glass consists of a device for dividing laminated glass, and a glass cutting table 30 with a cutting bridge 33 which can move along a support and on which a cutting head 38 for scratching plates of glass can move. The device for dividing laminated glass is located on one of the edges of glass cutting table 30 which run parallel to cutting bridge 33. On cutting bridge 33 of glass cutting table 30 there is stop 40 for orienting the laminated glass in the device for dividing laminated glass. Thus the amount of space required is reduced. The device for dividing laminated glass can also be made narrower or can have only one movable support 5 if a support 2 affixed to the frame is made integral with the bearing surface of glass cutting table 30. The glass cutting table is not used to divide the laminated glass: only its cutting bridge is used, and only as an adjustable support for the stop 40.

Claims

1. Apparatus for dividing laminated glass and for cutting non-laminated glass, comprising a laminated glass dividing work station and a separate non-laminated glass cutting work station;

said glass cutting work station including a substantially horizontal glass cutting table (30) having a plurality of sides, and an elongated cutting bridge (33) mounted for movement over the cutting table (30) in a direction (65) perpendicular to the length of the cutting bridge (33), said cutting bridge having a cutting head movable lengthwise of the cutting bridge, said cutting head being designed and arranged to score only one side of said non-laminated glass;

said laminated glass dividing work station including a device for dividing laminated glass located on one of the plurality of sides of said glass cutting table (30) which run parallel to said cutting bridge (33), said device for dividing laminated glass comprising means for scoring opposing surfaces of said laminated glass, means for bending said laminated glass, and means for cutting an intermediate plastic film, said cutting bridge (33) of said glass cutting table (30) having stop means (40'"'"') for positioning the laminated glass to be divided by said device for dividing laminated glass.

2. Apparatus according to claim 1, wherein the stop means (40'"'"') is formed by at least two stops spaced apart along the length of said cutting bridge (33).

3. Apparatus according to claim 1, wherein the device for dividing laminated glass has two rows of suction devices (22) which are aligned parallel to said cutting bridge (33) of said glass cutting table (30) for securing the laminated glass to be divided.

4. Apparatus according to claim 1, wherein the device for dividing laminated glass further comprises clamping means (20, 21 or 103, 104) for securing the laminated glass to be divided.

5. Apparatus according to claim 1, wherein a support (2) of the device for dividing laminated glass is integral with a bearing surface of said glass cutting table (30).

6. Apparatus according to claim 1, wherein the device for dividing laminated glass further comprises two supports, one of said two supports (5) being remote from said glass cutting table (30) and mounted to swivel around a horizontal axis (4) which lies in an area of a gap (3) between said two supports (2) and (5) for glass to be divided.

7. Apparatus according to claim 1, wherein a support (5) of the device for dividing laminated glass remote from the glass cutting table is mounted to swing around an axis (90) which is perpendicular to a coacting support (2) adjacent an end of an elongated gap (3) between said supports (2 and 5).

8. Apparatus for dividing laminated glass and for cutting non-laminated glass, comprising a laminated glass dividing work station and a separate non-laminated glass cutting work station;

said glass cutting work station comprising;

substantially horizontal glass cutting table (30); and

an elongated cutting bridge (33) slidably mounted for movement over the cutting table (30) in a direction (65) perpendicular to the length of the cutting bridge (33);

said laminated glass dividing work station being located adjacent said glass cutting table (30) and comprising;

means for scoring opposing surfaces of said laminated glass parallel to said cutting bridge (33);

means for bending said laminated glass;

means for cutting an intermediate plastic film; and

two supports for supporting the laminated glass to be cut;

said cutting bridge (33) of said glass cutting table (30) having a cutting head movable lengthwise along the cutting bridge and designed to be used for cutting non-laminated glass in the glass cutting work station, said cutting bridge also having stop means (40'"'"') designed to be used for positioning laminated glass in the laminated glass dividing work station.
