The work theory of parallel multi-roll straightener is first introduced in chapter two, and the key parameter's mathematical expression is acquired and simplified according to engineering application.
But in the 1960s, the expression "rolling stone" became famous in the world of rock-and-roll music. It became the name of a rock group, a song and a magazine.
