Apparatus for making pipe insulation
A roll forming apparatus used for rolling a material around a cylindrical core that comprises a core support, a roll support means, and a material supply means. The core support has an associated core rotation means for rotating the core about an axis at a controllable rate. The roll support means supports a plurality of forming rolls positioned to surround the core about the core rotation axis. The roll support means has a roll control means operable to both radially position the plurality of forming rolls relative to the core rotation axis so that they are equally spaced from the rotation axis. The material supply means is for supplying the selected material to the core at a material supply rate, and has an associated material supply control means for controlling the material supply rate.
