Abstract
Windshields are automatically mounted on automobiles on the assembly-line by advancing a gripping device carrying the windshield and associated position sensors relatively towards the automobile, moving the sensors over a windshield opening in the automobile body shell and across edges of the shell defining such opening to provide signals indicating the position of such edges. Such measurements take place firstly on a gross scale and subsequently on a fine scale along at least four axes during the mounting process. The gross position of the windshield opening is first detected using the gross sensors. Starting from a reference point determined in the course of the gross measurement, a gripping device is then moved towards the upper edge of the windshield opening until a first of two fine sensors moves across such upper edge when the gripping device is pivoted around the detected point until the second fine sensor also moves across the upper edge. The positions signalled by such sensors are used to calculate and compensate for a position error in the angular presentation of the window.
