Customized Modular Unwind Stands
Whether the application requires a retrofit to an existing machine or a complete stand-alone solution, Double E has the capability of engineering a roll stand to accommodate most standard dimensions and configurations.
Double Retrofit Unwind Stand
This custom stand was created for a supplier of plastic sheets and roll stock. The customer needed a bolt on double unwind stand with closed loop tension controls load cell frames for regulating tension.
This stand consisted of two DG-2000 aluminum bladder shafts held by four safety chucks and regulated by two Re pneumatic CX.250 brakes.
Triple Stand-alone Unwind Stand
The triple unwind stand is a unique design that was engineered for a producer of laminated film. The customer needed a more efficient method for manufacturing a five-layered material. Since the customer already had three individual stands, Double E engineered this stand to replace one of those single unwind stands to give them a total of five unwind sections.
This stand consisted of a control panel with three Re EP.25 T-One controllers, safety chucks holding three DG-2000 aluminum bladder shafts and regulated with Re TC load cells and pneumatic brakes.
