Abstract
Apparatus and methods for monitoring the application of a viscous material onto at least one moving strand or other narrow substrates. A detection unit, such as a machine vision system, an infrared sensor, an ultraviolet detector, or a light curtain with multiple detectors, senses radiation originating from the viscous material after it is applied to the strand or strands and, typically, before each strand is contacted with a substrate. The detection unit determines a detected value representative of a characteristic of the pattern from the sensed radiation, compares the detected value with a reference value representative of a desired standard for the characteristic, and outputs a signal in accordance with the result of the comparison.
