The "fixed sensor rule" is fundamental to unwind guiding physics and is the opposite of rewind chasing: The Logic: In unwind guiding, you are positioning the web to enter the machine at a specific target location. The sensor acts as that target. The …
[rr] actuators are specifically designed for hydraulic cylinder replacement in unwind and rewind guiding applications: What You Eliminate: Hydraulic fluid and the risk of product contamination from leaks Filter changes and fluid maintenance (typically 2-4 …
The choice between edge guiding and line guiding depends on what defines "correct position" for your process: Use Edge Guiding When: The physical web edge is your reference (e.g., die-cutting to edge, edge-aligned lamination) Material has consistent, …
In rewind chasing applications, the sensor must be mechanically attached to the shifting stand because the control system is designed to keep the sensor output at "zero." When the sensor moves with the roll, the system naturally drives the stand until the …
[rr] electromechanical rewind guides can handle loads up to 30,000 lbs (13,600 kg) when paired with low-friction linear rail bearings (coefficient ~0.01). Key specifications: Maximum thrust: 50–1,500 lbf (222–6,670 N) Stroke length: 1–12 in (25–300 mm) …
[rr] rewind guides use electromechanical actuators (RLA and BLA series) instead of traditional hydraulic cylinders. This completely eliminates: Hydraulic fluid —no oil to leak, change, or dispose of Filters and seals —no consumables to replace quarterly …
Yes. The [scu5] and [scu6x] controllers can process two sensors simultaneously with independent enable/disable control. This is ideal for bidirectional coating machines that run forward and backward between passes. Typical dual-sensor configuration: …
Telescoped (uneven) roll edges typically result from: Response lag: Hydraulic systems have inherent lag from valve response and fluid compressibility. By the time the guide reacts, the web has already wandered. Valve balancing issues: Unequal …
No. [rr sensors] are available in apertures from 48mm to 960mm, allowing a single sensor to accommodate a wide range of web widths without repositioning. For example, an [odc 288] sensor can detect edges anywhere within its 288mm (11.3 in) sensing range. …
Teams from the University of Oklahoma and Oklahoma State University were first-place division winners of the Donald W. Reynolds Tri-State collegiate business plan competition in Las …
