Abstract
A robot-held tool for applying a sealing strip to a flange comprises rollers which are contra-rotated by a motor within a housing and which engage opposite sides of the sealing strip to press it onto the flange, downward pressure onto the sealing strip being maintained by a non-driven roller. The housing is carried by a frame which is in turn connected to the robot via a coupling. The frame is freely angularly movable relative to a shaft which supports the housing. When the rollers are energized, they pull the tool along the flange. When a curve in the flange is reached, the housing and its supporting shaft automatically swivel relative to the remainder of the frame and to the robot. The robot then thereafter re-positions the frame back into the previous position which it had relative to the housing. In this way, the majority of the guiding of the tool along the flange is carried out by the tool itself and programming and adjustment of the robot are simplified. A hand-operated version is also disclosed.
