Have you ever needed to measure or control tension on multiple strands of web as they are being wound onto individual winders or takeups? A typical example is the case where a wide web of delicate or extensible material passes through a slitter station and the narrow strands that exit need finely controlled tension as they are being wound onto individual winders with individual cores. Even when differential winding shafts are used, uniform winding tension is required to achieve roll-to-roll consistency of the finished narrow web rolls. Gauge band variations across wide film substrates (being slit and rewound) add a dimension of variability in the winding process that can make fine tension control on the individual strands critical.
DFE was the sole tension equipment manufacturer years ago to release a multiplesegment
tension transducer roll with ten individual tension sensor modules side-by-side on one idler roll.
Products & Services
Tension meters are instruments that measure tension in cable, fiber, belts and webs, or sheets.
Web tension sensors are used to measure static or running tension in webs or sheets during the manufacture of textiles, paper, and other sheet materials.
Coil winding and unwinding machines are used for winding webs, paper or wire into coils or unwinding webs, paper or wire from coils.
Converting machines are used for cutting and packaging large, usually roll stock, materials into smaller, usable shape and sizes.
Web and roll coaters are used to rapidly apply controlled layers of paint, protective films, adhesives and other types of coatings onto the moving surface of paper, plastic film, coil stock, metal foils and other sheet materials.
