(1) The roller stand, driven by the rotation of roller pairs, adjusts the distance between roller centers within specified limits, is suitable for weldments of different diameters, and ensures the cylindrical weldments are placed flat.

(2) Utilizes a silicon-controlled rectifier-powered DC motor for driving, offering stepless speed adjustment, wide welding speed range, and stable speed; Time定额, Material consumption定额, Cutting tools and gauges, and fixture statistics and summaries.

(3) Versatile and widely applicable.

(4) The combination roller design features steel wheels wrapped in rubber, ensuring smooth transmission, high friction, and extended lifespan.

(5) Self-adjusting roller stand with a large number of rollers, applying minimal pressure to the workpiece, thus preventing the work surface from developing cold working hardening.
