Web Tension Controller

The SteadyWeb™ 5 Digital Tension Controller from Dover Flexo Electronics (DFE) is now available with Ethernet connectivity for remote PC or wi-fi smart-device access. With closed-loop digital PID control, the SteadyWeb™ 5 maintains set tension on the web to improve process consistency. The large LCD with color graphics simplifies setup and configuration. www.dfe.com

Bowed Rolls for Narrow Web

Ideal for narrow-web applications such as removing web wrinkles or controlling separation of slit webs, Perma-Bow™ bowed rolls from NimCor are as small as 1.5˝ diameter. Perma-Bow rolls can operate at full line speed while the roll apex is rotated to aid in separating slit webs or eliminating soft spots and wrinkles. Larger Perma-Bow bowed rolls are available in 3.5 to 7.5˝ diameters with fixed or adjustable bows and optional drive pulley. Roll coverings are available to meet any web or environmental challenge. www.nimcor.com

Narrow Web Vacuum Rolls

Webex offers a narrow-web vacuum roll custom-engineered to provide precise control over super-sensitive optical films. The 6˝ diameter roll body features a highly polished stainless steel finish with a series of micro grooves and port holes that produce an ultra-gentle web gripping force. Custom vacuum rolls can have adjustable active zone widths from within a few inches to nearly the entire face length of the roll. Active wraps zone are typically not adjustable and set according to the customer's web-wrap specifications. The cantilever design on this driven vacuum roll is for a clean room web-handling application. www.webexinc.com

Dancer Position Sensor

The Montalvo Corporation offers the DPS-1 Dancer Position Sensor commonly used on rider arms, dancers, accumulators/multi-pass dancers, and a large range of other tilt applications. The DPS-1 is a dual-axis sensor which makes it a versatile and user-friendly tilt sensor. It delivers a linear 0-5 V signal proportional to the dancer/rider arm angular position. Benefits include: non-contact; fast response time; high resolution/sensitivity; and no-tools, zero-point calibration. www.montalvo.com

Treater Rolls

PFE Rolls offers high-tolerance treater rolls for flame treating plastic films prior to package printing applications. Finishes include chrome plated or plasma coated surfaces. PFE also produces corona treater rolls for similar applications. Rolls can be manufactured up to 500˝ in length and 62˝ in diameter. www.pferolls.com

Leaf Shaft for Narrow Web

Tidland G690 Leaf Shaft from Maxcess is a new design that features an external bladder air system with four expanding leaves for improved performance and ease of maintenance in narrow-web applications. It uses a proven air system design that insures maximum up-time. The expanding leaves improve core life and provide superior torque for consistent and predictable wound roll tension. www.maxcessintl.com

Differential Shafts

The Series 1250-DFX differential shafts are designed to maintain precise web tensions. The shafts can wind multiple cores and/or different width cores at very low web tensions. Each core can slip at a controlled speed when proper air pressure is maintained. The temperature resistant segments on the tension ledge expand outward when inflated, generating resistance against the inside diameter of the core. The resistance is proportional to the area that is contacted. www.goldrod.com
