ABSTRACT:
A tool for applying a channel-shaped sealing strip to a flange comprises two parallel rollers which are contra-rotated by a motor which engage opposite sides of the sealing strip to press it onto the flange, downward pressure onto the base of the sealing strip being maintained by a non-driven roller rotatable perpendicularly to the other two rollers. The latter roller is vertically supported on supports whose upper ends are slidable within chambers and sprung-loaded downwards. The tool must exert sufficient pressure downwardly onto the inverted base of the sealing strip via the perpendicularly arranged roller to push the supports of this roller upwardly such that a striker actuates a pneumatic or electrical switch. When this happens, the motor is energized and the other two rollers drive the tool along the flange, thus pushing the strip firmly onto the flange. The switch stops the motor automatically if insufficient downward pressure is applied.
