Problems and Possibilities in Sliver Monitoring

Abstract

Sliver monitoring permits the reporting of errors at the time the material goes out of tolerance during processing. This can greatly reduce the waste of material, time, and money, and it can also improve the quality of the product. Adequate monitoring is only possible if the requisite parameters are measured, but most measuring systems react to changes in several parameters and create ambiguity. Currently, none of the parameters such as fiber length, crimp, and silver bulk are measured continuously, even though better system control would be likely if variations in these data could be incorporated into the control devices. This paper discusses these problems in greater detail and suggests a number of possibilities of extending the range of data available for use in monitoring and control systems.
