The contruction of this rolling machine isin the form of 3-roller symmetry. 2.The top roller, in the central symmetry position over the two bottom rollers, does vertical motion up and down through screw, nut and worm transmission. 3. Decelerator gears bottom rollers providing torsion moment for coiling sheet metal. 4. The contruction of the machine is compact, operation and maintenance is convenient.
