One area of research at Georgia Tech recently has focused on the measurement of Card-web density. This research is part of a study to spin yarns directly from a card web thus eliminating several processes. A Card-Spinning system has been designed which can quantify the cross-machine and machine direction web non-uniformity using a non-contact web density measurement technique. The web monitoring system for Card-Spinning uses a line scan camera to capture the image continuously and is equipped with an image analysis program, to characterize the web quantitatively, predicting the product quality. A multifunctional graphical interface has been designed for the image analysis program, which can be used to calculate the statistics for the non-uniformity of the card web both online and offline. This would help in characterizing the nature of non-uniformity and to understand the system better before employing methods to improve it. This paper discusses the development and results from the work.
