English: An overlock stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming. Usually an overlock sewing machine will cut the edges of the cloth as they are fed through (such machines are called ‘sergers’), though some are made without cutters. The inclusion of automated cutters allows overlock machines to create finished seams easily and quickly. An overlock sewing machine differs from a lockstitch sewing machine in that it uses loopers fed by multiple thread cones rather than a bobbin. Loopers serve to create thread loops that pass from the needle thread to the edges of the fabric so that the edges of the fabric are contained within the seam.

Français : La surjeteuse est un type particulier de machine à coudre, elle permet de couper, piquer et surfiler un ou deux tissus en une seule opération. Cela permet à la fois d'assembler des tissus et d'effectuer les finitions. Le principal point utilisé est le point de chainette, c'est ce point qui fut le premier à être mécanisé par Barthélemy Thimonnier. Les coutures effectuées sont élastiques et particulièrement adaptées aux tissus modernes comme le jersey et le lycra.
