ABSTRACT:
A strip builder for winding a material strip about a rotating core includes a traveling applicator head assembly for receipt of the material strip from an upstream extruder station and transport of the strip to a downstream rotating core. The assembly includes a central support arm in longitudinal travel along the rotating core. Attached to the central support arm is a belt roller, an applicator roller spaced therefrom and a belt drive coupled therebetween. A conveyor belt is wound about the belt roller. Upon rotation of the core, the rotation of the applicator roller rotates the belt roller coupled thereto. Rotation of the belt roller drives the conveyor belt towards the core with the material strip thereon. Upon the belt passing between the belt roller and displaced applicator roller, the strip is stretched and deposited onto the applicator roller for subsequent deposit onto the rotating core. A traveling stitching roller subsequently smoothes the material strip deposited on the rotating core. The applicator and stretching rollers are pivotable relative to the central support arm such that pressure along the central support arm can be equally distributed to the applicator and stretching rollers and onto the rotating core.
