ABSTRACT:
A system for determining the basis weight of cord reinforced tire fabric which involves the use of two radiation source, for example a collimated x-ray beam, and a beta ray source. One of the radiation sources and its corresponding sensor (e.g., the x-ray source) is used to determine the fractional area of the fabric not containing steel cords, while the other (e.g., the beta ray source) is used to measure the average attenuation of radiation passing through the fabric. Both sources and their corresponding sensors are movably mounted on a pair of beams which extend across the width of the fabric web. The source sensor assemblies continuously scan across the fabric width so that information from the entire fabric area is obtained.
