An overlock machine is designed for easy placement of a thread through a looper. The members which would obstruct access to the looper are mounted on a movable portion of a bed frame. By swinging open the movable portion, the obstructing members are moved to their inoperative position. A fixed knife only, or both the fixed knife and the movable knife are mounted on the movable portion.
