ABSTRACT:
A tool is described for assembling a length of sealing strip onto a mounting flange around a door opening in a motor vehicle. The strip has a channel-shaped gripping part whose walls are initially splayed apart so that it is an easy fit onto the flange. It carries a tubular sealing part. The tool comprises a roller which engages the outside of the base of the channel of the gripping part and a perpendicularly mounted roller which engages the outside of the tubular sealing part of the strip and, via this sealing part which it compresses, exerts a side force on the corresponding wide wall of the channel of the gripping part. A flange rigid with the roller engaging the gripping part itself engages the opposite side wall of the gripping part. The two rollers may or may not be geared together and are driven via a flexible drive shaft by a motor. The tool thus travels along the length of the sealing strip which is drawn off a coil or other supply. As the tool travels, it closes the splayed apart walls of the gripping part towards each other so as to press them firmly into gripping and sealing contact with the surfaces of the flange, in which position they subsequently hold themselves.
