Abstract:
A roll forming apparatus for rolling a selected material around a cylindrical core, the apparatus comprising:(a) a core support for supporting the cylindrical core, said core support having an associated core rotation means for rotating said core about a core rotation axis at a controllable rotation rate; (b) a roll support means for supporting a plurality of forming rolls positioned to surround said core about said core rotation axis, said roll support means having a roll control means operable to both radially position said plurality of forming rolls relative to said core rotation axis and constrain said plurality of forming rolls to be equally spaced from said core rotation axis, to provide integrated adjustment of said plurality of forming rolls to control a radial dimension of a substantially symmetrical forming space defined by said plurality of forming rolls; and, (c) a material supply means for supplying the selected material to the core at a material supply rate, said material supply means having an associated material supply control means for controlling said material supply rate.
