Rectangular duct branch, angled: flat patterns
A rectangular branch leaves a rectangular trunk at whatever angle the run needs, leaning along it, the height the same throughout. The top and the bottom are cut to the plan; the trunk's back is straight, and each side bends once where the branch leaves the trunk.
A rectangular branch off a rectangular trunk at any angle, of one height; five plates.
Sizes you enter
- Trunk width (W): Across the trunk, seen from above, on the surface chosen under Sheet.
- Trunk, first end (A1): From the trunk's first end to where the branch's centre line crosses the trunk's.
- Trunk, second end (A2): From that crossing to the trunk's second end.
- Branch width (w): Across the branch, square to its centre line.
- Branch reach (R): Along the branch's centre line, from the trunk's centre line to the branch's end.
- Height (H): Across trunk and branch, seen from the front, the same all along.
- Branch angle (A): Between the trunk's and the branch's centre lines, the branch leaning towards the second end; 90° square.
What you get
The exact flat pattern of the part, worked out for the sheet thickness measured on the inside, the mean or the outside, with numbered press lines, the part in 3D, its weight and cutting length, and a DXF for laser, plasma or waterjet cutting (STEP as well).
