Product Description: The Segmented Tension Roll transducer is a specialty idler roller that measures tension on multiple individual web strands in a slitting and rewind environment, or at multiple points across the width of a single web in a converting or film application.
In recent years converters of extensible materials have been seeking the capability to measure and control process tension on two or more parallel web sections as they are being wound onto individual roll cores on the same machine.
The Segmented Tension Roll can also be used for inspection of the tension profile on incoming roll stock. A converter can quickly check for substrate non-compliance on purchased rolled material by setting up a tension-profile monitoring station at Receiving or Incoming QC and rejecting defective material before it reaches processing.
A typical segmented tension roll transducer consists of a single shaft containing a series of evenly spaced tension-sensing idler roll segments. Each roll segment has integrated tension sensors in both ends. Electrical connectors are installed on the shaft, as a group, at one end of the unit. The standard roll is aluminum with a smooth plain finish. Other finishes are available by request. The shaft can be mounted in a carrier frame that has one or more supports placed between rolls if desired (as pictured below).
The STR transducer is available in two frame sizes; size 1 and size 2. The size 1 STR has a 3" diameter standard roll, and the size 2 STR has a 4" diameter standard roll. The maximum number of segments is limited to ten for the size 2 transducer and 5 for the size 1. The minimum number of segments is two. Maximum shaft length is 120"
Benefits/Features
- Measure tension on parallel web strands or at multiple points across a wide web
- Choose length to fit machine or press frame
- 50:1 Effective load sensing range
- Load ratings from 12 - 400 lbs (55 -1800N )
As with our standard Tension Roll® transducers the ordering process is simple. To request a quotation you'll need to specify your desired shaft length, roll diameter, load rating, and any special finishes or options. You'll also need to specify the width of each tension-sensing idler segment and the spacing interval you desire between each segment. Every Segmented Tension Roll from DFE is made to order, so please ask your DFE Sales Engineer or Applications Specialist for help with the details and for a quotation.
