Abstract
An apparatus for forming a carcass for encasing a tubular member including a driven rotor (20) having a front face rotatable about a pivot axis and a spool mandrel (38) positioned eccentrically on the driven rotor (20). The spool mandrel (38) is adapted to rotatably mount a roll of coiled strip material (32). The rotor (20) includes at least one counterweight (60) 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 (32) is removed from the roll. At least one pusher roll assembly (75) is mounted on the front face and contacts a portion of the strip material (32) to partially deform the coiling of the strip material as the material is removed from the roll. An anti-kink roll assembly (90) prevents kink deformation of the strip material (32) during the formation of the carcass.
