Patent Number Title Of Patent Date Issued
5073714 Method and apparatus for detecting amplitude and frequency of web flutter using infrared optical December 17, 1991
Web flutter in a papermaking machine is monitored by a device which illuminates a portion of the web with infrared light and uses an infrared sensor to monitor the resulting infrared light scattered back from the web. Preferably two infrared light transmitters are used which are angled
5022166 Flutter suppression air foils June 11, 1991
Apparatus and methods for reducing the amplitude and frequency of web-edge flutter associated with drawing web materials are provided. The apparatus includes a pair of air foils disposed proximate to a pair of opposing planar surfaces of the web. Each of the air foils includes a first co
4992142 Method for determining amplitude and frequency of web flutter February 12, 1991
An apparatus and method for determining the frequency and amplitude of flutter of a moving web in a web manufacturing operation, is shown to include a sensor for sensing the pressure of air in a region proximate the web and for generating a pressure signal reflective of the air pressure
4968386 Apparatus for determining amplitude and frequency of web flutter November 6, 1990
An apparatus and method for determining the frequency and amplitude of flutter of a moving web in a web manufacturing operation, is shown to include a sensor for sensing the pressure of air in a region proximate the web and for generating a pressure signal reflective of the air pressure
