A portable tool for fitting a channel-shaped sealing, trimming or finishing strip onto a mounting flange, such as around the door opening of a motor vehicle body, comprises two main rollers (38,40) rotatably driven in opposite directions about parallel axes (42,44) by a motor (30). The strip is placed on the mounting flange, preferably with its side walls splayed slightly apart. The tool is then placed over the strip on the flange so that the strip is in the gap (60) between the main rollers (38,40) which thus press the sides of the channel into tight frictional contact with the mounting flange as the rollers rotate and drive the tool along the strip. A further roller (52) rotatable about an axis perpendicular to the axes of the main rollers (38,40) exerts a downward force on the outside of the base of the channel of the strip. An additional guiding roller (54) is positioned in front of the main rollers (38,40) in the direction of travel of the tool and exerts an inclined force on a cosmetic lip on the outside of the strip, guiding the cosmetic lip, with the remainder of the stript into the gap (60) between the main rollers (38,40) and preventing any tendency for the cosmetic lip to force the tool off the strip. |
