Transverse Direction Orientation (TDO) Systems Uniaxial In-Line or Off-Line Cross-Web Stretching Superflex® Rail Hinge System Marshall and Williams Plastics is a recognized global leader and innovator in plastics orientation and casting equipment. Founded in 1920, Marshall and Williams built tenter frame systems for the textile industry and was the first to adapt this technology to orient plastic film and sheet. Transverse direction orientation of plastic film and sheet is accomplished by heating the web and stretching it in the transverse (or cross) direction on a tenter frame. The tenter frame consists of two horizontal chain tracks, on which clip and chain assemblies ride, enclosed in an oven. Plastics Orientation www.parkinsontechnologies.com
