Introduction ARIS WPS is a revolutionary web edge sensor technology that employs fiber optics to accurately determine the position of a web material irrespective of its material properties. This edge sensing principle is unique and provides a true, …
Introduction ARIS Web Position Sensor (WPS) can use either infrared (IR) light or white light (WL) to detect the position of a web material. As a contrast sensor ARIS WPS with WL option can detect visible contrasts on the web. The revolutionary sensor …
Introduction Regulating the lateral position of the web material in a roll-to-roll machine is critical for a wide variety of converting applications. Variations in lateral position can result in substandard finished product. In extreme cases the web …
Introduction In a previous whitepaper the disturbance rejection performance of Roll-2-Roll Technologies' web guides was reported for sinusoidal and step disturbances. This whitepaper reports the performance of the same web guide with a high speed actuator …
Introduction The performance of a web guiding system depends on the positional accuracy of the guide mechanism, the accuracy of the sensor, the precision of the sensor, the dynamic response of the sensor (speed of measurement) and the dynamic performance …
Introduction In most roll-to-roll applications, the web is guided based on the edge position of the material. Often this alignment based on web edge is sufficient. However, in certain applications the alignment may be based on a feature on the web that is …
Stop sensor repositioning – wide aperture handles full width range without adjustment Eliminate edge quality issues – precise guiding prevents trim waste and edge defects End changeover delays – no sensor adjustment needed between width changes Remove …
Why is a web guiding system needed? Web material transported within converting machines will not always track straight. A web guiding system is required for proper alignment of the material. A variety of factors such as, poor quality raw materials, …
Web materials are not perfect, and neither are converting machines. Web guides are needed to reduce waste due to web misalignment. Web Guiding Principles Video courtesy of Jerry Brown at normalentry.com Web guides are able to steer or guide the web …
As we search for the most appropriate equipment for our operation, we are faced with the task of selecting from myriad options based on technical data and specs. Through these data, manufacturers are trying to present the benefits of their products based …
