Plastic Extrusion Controls

Plastic Conduit is wound to a steel reel over seven feet in diameter. The final product is conduit for buried underground wiring and fiber optic cable. Our customer requested a system to control the side-to-side bobbin winding for even layers of material.

Design of the system includes, light curtain height sensor for speed loop control of the winder reel speed with a high perfomance vector variable speed AC Drive.  The rotation of the reel is electronically geared to move a servo drive ball screw to guide the conduit to the reel.
