Achieve performance advantages by down-gauging plastic film and sheet while retaining or enhancing physical properties. Founded in 1920, Marshall and Williams developed the industry's first plastics orientation system. Today our MDO, TDO and BIAX systems are installed worldwide to produce PS, PP, PET, PLA, PETG, PTFE, PVDF and many other specialty plastics film and sheet.
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.
The 475DJ/Tenter Clip is designed to be used on either new TDOs or as replacements on existing machines for orientation of polypropylene, polystyrene, PET and many other specialty films.
The clips have an advanced high strength 4 3/4" (120 mm) pitch chain, and a dual jaw with a low profile. The increased holding power significantly improves the handling of wide films at high speeds.
