Definitions
- ABSTRACT I A packer head concrete pipe machine operable to make a cylindrical concrete pipe in an upright mold.
- the machine has a triangular frame assembly formed with three upright frame members fixed to each other with cross braces.
- a rotatable turntable has a center hole for accommodating one of the frame members.
- the turntable carries three molds and is sequentially rotated to move the molds in longitudinal alignment with the packer head and a cylindrical core having vibrating units.
- Three hydraulic cylinders function to move the packer head longitudinally of the mold during formation of the pipe.
- the core follows the packer head through the pipe.
- a conventional packer head concrete pipe machine has a vertically moving rotating packer head which functions with an upright mold to form a concrete pipe.
- the packer head is mounted on a cross head which supports the power means and transmission for rotating the packer head.
