A packerhead, a concrete pipe making machine having said packerhead, and a method of making concrete pipe are disclosed in which twist forces on the reinforcing wire cage of the pipe and concrete voids are eliminated by rotation of the longbottom and rollerhead portions of the packerhead in opposite directions. The peripheral speed of the system is also increased over conventional systems.
