The double-seaming machine was invented by Edward Converse and Seth Peck.

• A. False
• B. True
• C. It was invented by someone else
• D. It did not exist

Answer: (A)

Double-seaming machines are used to hermetically seal metal cans by forming a double interlocking seam between the body and the lid. This seam is created through a sequence that folds the lid edge and body flange together twice, producing two tight folds that hold in contents and prevent leakage. The attribution in the statement isn’t supported by historical records, and the invention of the double-seaming machine is credited to other people in the canning industry, not to Edward Converse and Seth Peck. So the statement is false—the technology and its development belong to different inventors, with the double-seaming method becoming standard long before or apart from those names.
