Apparatus for making pipe insulation
A roll forming apparatus for rolling selected materials around a cylindrical core. The apparatus comprises a core support, a roll support device, and a material supply device. The core support is used to support the cylindrical core. The core support has an associated core rotation device for rotating the core about a core rotation axis at a controllable rotation rate. The roll support device supports a plurality of forming rolls positioned to surround the core about the core rotation axis. The roll support device has a roll control mechanism operable to both radially position the plurality of forming rolls relative to the core rotation axis and to constrain the plurality of forming rolls to be equally spaced from the core rotation axis in order to provide integrated adjustment of the plurality of forming rolls to control a radial dimension of a substantially symmetrical forming space defined by the plurality of forming rolls.
