ABSTRACT:
A bead or caulking material is applied to a workpiece, such as a window frame, utilizing a moveable carriage holding a bead dispensing nozzle thereon. The nozzle is mounted on a platform moveable relative to the carriage. The carriage is moved along a predetermined path relative to the workpiece. Bead or caulking material is simultaneously dispensed from the nozzle onto the workpiece. Additionally throughout the movement of the carriage, the nozzle and platform are biased to maintain engagement between a guide surface mounted on the nozzle and a reference surface. The reference surface may be formed as a portion of the workpiece. The platform may include a pair of orthogonally arranged slides with piston cylinder assemblies utilized for biasing each of the respective slides. Sensors may be provided on each of the cylinders for sensing biasing parameters relating to the biasing of the nozzle and the platform with the sensed parameters utilized for controlling the movement of the carriage.
