  • Concrete pipe manufacturing machinery and methods
    Patent number: 7125239
    Abstract: A concrete pipe making machine having a packerhead consisting of a rollerhead and a longbottom in which the rollerhead and longbottom are quickly assembleable and disassembleable as a unit from the packerhead drive means with one connector and brought into final adjustment off the machine, said drive means providing no obstruction to the flow of wet concrete toward the compaction area, the speed ratios between the rollerhead and longbottom being infinitely variable, and easily replaceable protective wear rings for precluding erosive deformation of the permanent parts of the machine due to undesired penetration of wet concrete into the longbottom.
