An apparatus for connecting strips, in which a rear end portion of a preceding strip and a front end portion of a succeeding strip are cut and brought into contact to each other so that a butt welding of the contacted portions may be carried out to connect both the strips. A carriage is provided for carrying a cutting device for cutting the end portions of both the strips. A finish-machining device is provided for finish-machining the cut end faces of both the strips and a welding device for butt welding both the strips along a contacting line of both the strips is installed so as to be movable in a line substantially parallel with the contacting line of both the strips. Die wears and burrs incidental to cut faces can be prevented from forming and the highly accurate contacted state of strips can be achieved, thereby improving the quality of the welded portion.
