Slitter rewinders are used extensively in the flexible packaging, label, and plastic film industries and are easily the most popular type of slitting machine sold in the industry.
Some applications require a specially engineered solution. Whether it’s as complex as a fully automated machine for slitting thermal transfer ribbons or as straightforward as a simplex machine for slitting back sheet, Dusenbery can engineer a solution to fit your needs.
The Dusenbery® Model 765 AB Manual Core Cutter provides an efficient method for precision cutting of cores with 3” to 6” ID and up to 90” long. Ruggedly built for low maintenance with a long lasting steel cutting platen. The platen may be easily shifted to different cutting positions to present a fresh cutting edge. Adapter ring assemblies, designed to accommodate a wide range of core sizes, are also quickly changed by removing a single socket head screw.
The Dusenbery roll editor is a versatile machine designed to provide a means of salvaging product by facilitating the removal of material and/or winding defects wound in a roll. Two fully cantilevered mandrels are provided to ease the loading and unloading of rolls.
Parkinson Technologies carries a complete line of Dusenbery parts including shear knife, score knife, razor slitting, core cutter knife, and accessories. The following is a list of commonly requested parts. If the part you are searching for is not listed, please contact the Dusenbery parts department;

Marshall and Williams Plastics is a recognized global leader and innovator in film stretching lines for biaxially oriented and other plastics production lines. Films include PS, PP, PET, PLA, PTFE, PETG, PVDF, and many other special films that require or are enhanced by the biax process. Founded in 1920, M&W has been offering customers a single source supply by providing complete biaxial orientation system integration.
System Offerings
Marshall and Williams Plastics is a recognized global leader and innovator in oriented film stretching. Marshall and Williams designed and built the first Machine Direction Orienter in 1961; and now with over 50 years of MDO experience, the brand remains one of the most trusted and experienced in the plastics orientation equipment industry. Machine direction orientation of plastic film and sheet is accomplished by heating the web and stretching it in the machine direction over a series of rollers. The device is commonly called a Machine Direction Orienter (MDO).
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.
Marshall and Williams offers the industry’s most complete range of casting systems for sheet and film processing that incorporate large diameter casting rolls or multiple cooling roll designs in addition to innovative pinning options to meet a wide range of production and material requirements. Each system is custom engineered to provide modular flexibility, precise controls and drive coordination with unique gap control options. Marshall and Williams Plastics is a recognized global leader of plastic sheet and film processing equipment and continues to push innovative designs for technology advancement.
In plastics extrusion, having the right screen changer for your material’s filtration requirements can make the difference between profit and loss. Parkinson Technologies’ line of Key Filters products offers custom engineered solutions and turnkey services to meet melt filtration needs for thermoplastic materials.
The new KCH joins the best features of the prior KC and KCN product lines. The KCH delivers the same uniform continuous extrusion pressure, varying as little as ±20 psi. However, with hydraulic puller action, the KCH can react rapidly to disruptions caused by varying contaminant levels.
No process interruption translates into increased production and decreased scrap, bringing maximum efficiency to your extrusion operation.
The MSC Manual Slide Plate Screen Changer offers an economical, efficient way for plastics processors to filter contaminants from polymer flows. The MSC can be used to filter almost any type of thermoplastic material. Utilizing pressure activated seal technology, the MSC remains leak free under extrusion pressure yet is easily shifted when the pressure is removed. The MSC is shipped fully assembled requiring minimal downtime to install.
The MSC Screen Changer is ideally suited in applications where process shutdowns occur and there is no loss of production directly related to the screen change itself. It has significant advantages over stationary screen pack breaker plates that can only be changed by machine disassembly.
The CSC offers an economical, efficient way for processors to filter contaminates from polymer melt flows and is used to filter almost any thermoplastic material. Utilizing proven pressure activated seal technology, the CSC remains leak free under extrusion pressures, while the gear reduction ratchet action is easily shifted when the pressure is removed. The CSC is fitted directly to the extruder barrel flange making maintenance and screw removal easier.The CSC Compact Screen Changer is suited in applications where the process is shut down periodically for reasons not related to the screen changer, hence there is no lost production due to the screen change.
Key Filters is a supplier of the Reverse Dutch Twill Weave filter belts used in ribbon style continuous screen changers. A large inventory of standard meshes and sizes are stocked for immediate delivery. Please contact us regarding your specific requirements.
Parkinson Technologies, Inc. has introduced a first-of-its kind feature to its Key Filters brand that will lend added safety and efficiency to continuous belt screen changer operation. Called ScreenLync™, this innovation enables the operator to hook the new full RDW (Reverse Dutch Weave) roll to the end of the depleted RDW roll in less time than is currently required, thereby reducing operational downtime.
