Davis-Standard Cast Film Automatic Model 2200 Winder
Davis-Standard's cast film winder offering ranges from simple surface winders to center winders with automatic core and roll handling. Combination center-surface winders are also available. Series 2200 Ideal for winding stretch film wrap, this winder features a servo-index drive with a high rotational speed of approximately one second, eliminating much of the scrap generated during a longer indexing cycle and boosting tension control. The automatic core-feeding system makes it possible to do core loading, roll transfer, check and shaft deflation, shaft extraction, roll unloading and shaft retraction in less than a minute. The winder also features a surface driven lay-on roll that provides a light controllable lay-on force, critical when winding high quality reels of stretch film. It is available in 84-inch (2134 mm) and 104-inch (2642 mm) widths and with a center bearing support for widths up to 180 inches (4572 mm). Horizon Series Turret Winders Designed for winding barrier, lamination and hygienic films, it can produce roll widths as small as 4-inches (100 mm). It features touch screen controls, a short web path, automatic cut/transfer, transducer web control and DC drive units. The winder's linear horizontal lay-on roll contacts the winding roll parallel to the floor, providing precise control of the lay-on pressure. Options include swing out shafts, gap mode winding and in-line slitting. Slitter assemblies can be located close to the winding core for superior roll edges.
Davis-Standard Cast Film Epic III Control System
Davis-Standard's EPIC III is an advanced WINDOWS NT based touch screen extrusion process control system offering complete plant management and process control capabilities. The EPIC features Dynamic Data Exchange (DDE), Object Linking and Embedding for Process Control (OPC), networking and multi-tasking features and an extensive security system. EPIC data and files are readily accessible using DDE and OPC to link information with compatible WINDOWS NT programs. Since it's a network compatible system, an entire extrusion plant can be monitored from any networked PC in any office or on the plant floor, and users can integrate their own connection and remotely access data via Net DDE. The EPIC has customized control screens for simplified operation that are co-engineered with the customer to meet exact process requirements. Operators can take advantage of a complete line overview, or can view specific process details, line controls, extruder data and recipes. The system can only be accessed through multiple levels of security to protect critical set-up functions. Supervisory features include event logging, customized reports, SQC, historical trending, maintenance/troubleshooting data and configurable temperature and pressure set-up.
