Precise marking ensures the strip is positioned correctly before entering the next process, reducing turbulence and ensuring coiling quality. This tool typically consists of a base plate, a window, and a roller assembly. The rollers convert sliding friction into rolling friction, significantly reducing wear on the guide plate, extending its service life, and improving production efficiency and product quality.
