Modular Plastic Belt Curves
Overview
Zero tangent modular plastic belt curves are powered conveyor curve sections designed so the belt path does not require straight tangent sections before and after the curve. This enables tighter conveyor layouts while maintaining controlled product flow for bags, cases, and totes through direction changes.
Historically, straight tangent requirements were common on PVC belt curve styles, and earlier modular plastic belt and tabletop chain curve products typically required tangents. The zero tangent configuration eliminates that requirement to reduce overall footprint and simplify tight system routing.
