The present embodiments are directed to systems and methods for forming a pipe carcass. In one embodiment, a first series of forming rollers are configured for forming a primary carcass strip material. A second series of forming rollers are configured for forming a second strip material into a shape different than the primary carcass strip material. The primary carcass strip material and the second strip material, after being fed through the first and second series of rollers, respectively, are each fed concurrently into a plurality of winding rolls for assembly with one another.

Systems and methods for forming a pipe carcass using multiple strips of material

An apparatus for forming a carcass for encasing a tubular member including a driven rotor () having a front face rotatable about a pivot axis and a spool mandrel () positioned eccentrically on the driven rotor (). The spool mandrel () is adapted to rotatably mount a roll of coiled strip material (). The rotor () includes at least one counterweight () mounted on the front face that is dynamically movable to at least partially balance the changing weight of the roll of strip material as the strip material () is removed from the roll. At least one pusher roll assembly () is mounted on the front face and contacts a portion of the strip material () to partially deform the coiling of the strip material as the material is removed from the roll. An anti-kink roll assembly () prevents kink deformation of the strip material () during the formation of the carcass.
