Disclosed within is a slit section pass formation unit having a pair of rolls and a de-ribbing means, where the pair of rolls has a roll profile configured to produce a pair of slit rods with symmetrical dimensions, the pair of slit rods connected via a rib, and the de-ribbing means to remove the rib in its entirety forming a first slit rod and a second slit rod.

A method for synchronous and specified-length cutting of continuously-formed materials by multiple lathes connected in series in production lines of continuously-formed materials, such as steel pipes and steel sections. A synchronous and specified-length cutting machine having multiple lathes connected in series is provided with two or more lathes that are separately equipped with a cutting tool. The lathes are installed in series on a rail parallel to a material and are driven by respective driver means to move back and forth according to a set procedure; in the case that the speed of the lathe is synchronous with that of the material, the cutting tool on the lathe cuts the material according to a specified length. The cutting machine can be adapted to high-speed production lines, allows a small minimum specified length, possesses cutting tools having a long service life, and achieves smooth cuts.
