Abstract (en)
[origin: EP0916424A2] A dent portion in a sheet metal such as a car body is repaired by locating a bar above the dent portion, permitting a prescribed number of steel rods each having an engaging portion to be engaged to or inserted through the bar, welding one leading end of each of the steel rods to the dent portion in the sheet metal, and drawing the bar by using a drive means separately installed to pull up the steel rods together with the dent portion in the sheet metal, thereby to make the dent portion flat. The dent portion may be pulled out by locating a bar above the dent portion in the sheet metal, inserting a prescribed number of bolts through the bar, welding one leading end of each of the bolts to the dent portion in the sheet metal, screwing nuts to the bolts, and rotating the nuts to draw up the bolts. Thus, the dent portion can easily and appropriately be pulled out with a small rotating force. <IMAGE>
