Abstract: An apparatus for the automatic application of an adhesive bead to the frame flange of a window opening of a vehicle body has an all-round rail shaped in accordance with the flange and on which moves a carriage. The carriage supports a discharge nozzle by means of a guide column and a bracket arm, which is pivotable radially outwards with respect to the latter, in such a way that the nozzle can move to a limited extent relative to the carriage. The mobility of the discharge nozzle is controlled by a scanning wheel, which is located in the window frame when the apparatus is in operation.
