ABSTRACT:
In order to determine the spacing between the mutually facing inner surfaces (20, 28) of the glass sheets (1, 6) of insulating glass elements, and also the total thickness thereof, an apparatus for the assembly of insulating glass, with a conveying device (3) for a glass sheet (1) defining a reference plane (10) for one of the glass sheets (1) and with guide rollers (7, 8) defining a reference plane (11) for the second glass sheet (6), comprises tracer pins (12 and 13) which can be advanced perpendicularly to the reference plane (10, 11) into contact with the glass sheets (1, 6). Optionally electronic rulers (25, 26) are coupled with the tracer pins (12, 13), these rulers detecting the distance of the surfaces (20, 27), facing away from the reference planes (10, 11) of the one glass sheet and of the second glass sheet (1, 6). In order to determine the width of the spacer frame (5), a further tracer pin (13) is provided which can be advanced perpendicularly to the reference plane (10) into contact with a spacer frame (5) placed against the one glass sheet (1), an optionally electronic ruler (26) being coupled with this tracer pin.
