A wire coiling machine of simplified construction, direct one-to-one synchronized drive from a rear drive arbor through a pair of friction drive rolls astraddle it, to a pair of flexible drive shafts connecting the drive rolls to a pair of front forming rolls of essentially the same diameter as the friction drive rolls, the forming rolls being astraddle the front forming arbor; the drive arbor having a diameter essentially the same as the outer diameter of a coil being formed on the forming arbor, and the forming arbor having a diameter essentially the same as the internal diameter of the coil being formed.
