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.
Tidland’s Raptor Series Air Powered Lug Chucks are easy to use and maintain and help eliminate the core damage usually associated with shaftless applications. The Air Powered Lug Chuck is ideal for high-speed printing, laminating, sheeting applications on unwind flying or zero speed splicers and other shaftless unwind/rewind applications. Unlike other chucks, Tidland’s Raptor Series Air Powered Chucks offer on-machine maintenance and toolless adapter changes from 76.2 mm (3 inch) to 305 mm (12 inch) cores in less than 5 seconds.
Feather Light. Intense Grip. Incredibly Durable. Tidland’s Force5 air chuck offers the lightweight alternative to aluminum chucks at the lowest cost in the market. The Force5 can also take abuse in the toughest environments. The specially engineered polymer expanding element is not only designed for high durability in extreme conditions, but retains its shape over time for ease of insertion and removal. The Force5 are the lightest weight air chucks available and have the greatest gripping force with improved gripping during e-stop & high-torque applications. Paired with Tidland’s Ultrashaft carbon fiber air shafts or mandrels, you can safely change rolls from 76 mm (3 inch) to 152 mm (6 inch) ID cores.
Strong and versatile, Tidland Lug Shafts deliver superior performance in the widest range of converting applications. Unmatched for positive holding power, the lug-style design eliminates core damage, prevents roll slip through fast startups and shutdowns, and minimizes vibration at high web speeds. Simple modular construction and standardized components mean quick off-the-shelf spares service and easy in-plant maintenance when necessary.
Series 500 Lug Shaft – Air
The Series 500 Lug Shaft is designed for light- to heavy-duty applications in 50.8 mm (2 inch) to 152.4 mm (6 inch) ID cores; often used in center unwind and rewind applications with either fiber or steel cores. These reliable shafts are constructed of alloy steel, aluminum, or lightweight, composite materials – depending on usage and requirements.
Series 550 Lug Shaft – Mechanical
The Series 550 Lug Shaft is designed for medium- to heavy-duty in 76.2 mm (3 inch) ID cores; often used in center unwind and rewind applications with either fiber or steel cores. The shaft body is constructed of 4150 heat treated steel or lightweight, composite materials. Each shaft is built to order and has as much as 85% fewer moving parts than other mechanical shafts.
With Tidland’s Equalizer Model D3 Differential Air Shaft, operators can run a variety of different roll widths with adjustable pressure all along the length at the same time. The Equalizer D3 is guaranteed to provide core positioning with adjustable air pressure without spacers or core stop setup. It’s designed for duplex center or surface winders for multiple roll tension equalization. When not covered by the core, tension elements mechanically lock in place to secure core position through the entire run. The D3 requires no tools for core stops, no core stop positioning. Use these air shafts and say “No” to tools, spacers, core shifts and waiting for core position setup.
