What is the purpose of beading rolls in metalworking?

• A. To crimp sheet metal edges
• B. To turn beads on cylindrical stock
• C. To burr and wire edges
• D. To finish wired edges prepared in turning rolls

Answer: (B)

The purpose of beading rolls in metalworking is to turn beads on cylindrical stock. Beading rolls are specialized tools designed to create rounded or beaded edges on metal sheets or workpieces, which adds strength and improves the aesthetic appearance of the item. This process is especially useful in applications where a rounded edge is desirable for both functional and aesthetic reasons, such as in making drums, barrels, or any item requiring a smooth, finished edge.

Turning beads does more than just alter the shape; it can also prepare the edges for assembly with other components or enhance the load-bearing capabilities of the finished product. This capability is essential in various industries, providing structural support and durability while allowing for further processing or finishing.

While the other options mention processes that involve working with edges or shaping metal, they do not accurately describe the specific function of beading rolls. Therefore, the focused function of beading rolls as a tool for creating rounded or beaded edges on cylindrical stock makes this the correct choice.
