TS Load Cells provide the most consistent control of tension, no matter how the temperature changes throughout the day. In fact, all MAGPOWR Load Cells are designed with foil strain gauges that provide the lowest temperature drift rating possible (.02% per º C), which can mean the difference between a profitable web and a floor of wasted material.
These rugged load cells are extremely accurate devices used to measure tension in any unwind, rewind or intermediate web processing application. The unique low profile design minimizes space requirements inside the machine frames, thus maximizing the potential for web width. TS load cells are designed with mechanical overload stops in both force directions to eliminate sensor damage and the need to recalibrate even after extreme overloads, while also offering the flexibility of a variety of mounting styles and coupling options.
Split coupling models
Load Cells with Split Couplings can be used to measure web tension through dead-shaft or live-shaft idler rolls. With one load cell mounted to each side of the machine frame, the idler roll is supported between the two load cells. The resultant force of the web tension is measured as a load on the roll by the load cells.
The Split Coupling allows the idler roll to be easily installed after the load cells have been mounted to the machine frames. The coupling design also accommodates misalignment between the machine frames and allows for thermal expansion of the idler roll shaft during machine operation. The unique coupling design also allows its use in both dead-shaft and live-shaft applications.
In-roll coupling models
The In-Roll Coupling is designed to insert directly into the end of an idler roll. With one load cell mounted to each side of the machine frame, the idler roll is supported between the two load cells. The resultant force of the web tension is measured as a load on the roll by the load cells.
The In-Roll Coupling includes a spherical bearing to allow for smooth rotation of the idler roll and to accommodate misalignment between the machine frames. This coupling type eliminates the need for idler rolls with shafts and bearings, thus reducing the overall cost of the tension sensing system.
Wire pulley models
The Wire Pulley is used for single strand applications for any kind of material. When mounted to the side of a machine frame or bracket, a load cell measures tension in the strand as it passes over the nickel plated aluminum load cell pulley.
Inexpensive and effective, Tidland’s Automatic Lug Chuck is designed specifically to meet the needs of narrow-web converters. This chuck features spring-loaded, torque activated expanding lugs for economical die cut and trim removal in narrow web applications.
Series 850 takes our innovative two-piece expanding elements to a whole new level. The unique spiral design of the Series 850 provides a continuous 360º of radial grip and intrinsically equalized load distribution. These advanced shafts also feature a two-piece body design, self retraction, durable poly bladder, and a fail-safe multi-circuit air system, with check valves to ensure that a loss of air in one element will not affect the expansion and performance of the other elements.
The Series 850 Spiral Strip Shaft is designed for medium to heavy-duty in 75 mm (3 inch) to 406 mm (16 inch) ID cores. The spiral strip design of this shaft minimizes vibration to deliver smoother operation and higher speeds. It’s an ideal choice for surface winders or with lay-on rolls.
Years of successful roll control in the field testify to the excellent performance of the Leaf Shaft. Designed for a wide range of converting applications, these shafts are best for the elimination of thin wall core deformation. The 360º radial expanding grip along the entire leaf face delivers more winding surface and allows for the winding of single or multiple rolls, with or without cores.
With smooth, polished external leaves, these shafts are particularly suited for delicate materials. Leaf Shafts are built tough, with bodies constructed of standard steel, alloy steel or aluminum, and internal tubes made of durable, hard-wearing rubber. Simple modular construction and standardized components mean quick off-the-shelf spares service and easy in-plant maintenance when necessary.
Series 650 Leaf Shaft – designed for light to medium-duty in 2 inch to 6 inch (50.8 mm to 152.4 mm) ID cores, as well as in coreless operations. The versatility of this shaft has made it the most popular and widely used leaf shaft on the market today.
Series 750 Leaf Shaft – designed for heavy-duty in 7 inch to 24 inch (177.8 mm to 609.6 mm) ID cores, as well as in coreless operations. The largest diameter leaf shaft available, this shaft is excellent for tougher jobs such as winding metal and foil strips. It can also be used as a reel spool for Paper reels and large paper machines
Tidland’s Narrow Web Shafts were created specifically to meet the needs of narrow-web converters. These economical shafts are designed to fit any press — with cantilevered, drop-in, flange, and bar mounting styles available.
