<P>PROBLEM TO BE SOLVED: To provide a standard length cutting device capable of easily positioning a plurality of long materials while suppressing occurrence of abrasion, and cutting the long material into a certain length in a small error range. <P>SOLUTION: This standard length cutting device includes: transport rollers 2 for transporting a mounted long steel material W in its longitudinal direction; a stopper 3 abutting on the front end in the transport direction of the long steel material W to perform positioning in the longitudinal direction of the long steel material W; a pressing roller 4 for pressing the long steel material W against the transport rollers 2 and feeding the long steel material W forward by rotation; and a cutting blade 7 for cutting the long steel material W; wherein the pressing roller 4 includes a rotary shaft 10 decentered from the center axis 9, is arranged in parallel to the transport rollers 2 by being separated upward from the transport rollers 2, and is structured to position at an operation position to abut on the long steel material W when its center axis 9 side approaches a position facing the long steel material W and separates from the long steel material W when the center axis 9 side gets away from the long steel material W by rotating around the rotary shaft 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
