ABSTRACT:
An improved method for forming sheet metal around straight tubes and an apparatus for performing same is provided. A sheet is clamped along two parallel spaced apart locations by clamps by placing the straight part of the tube between said parallel locations, parallel with the clamps, and adjacent thereto. The clamps are then moved toward each other to thereby bend the sheet around the tube.
