摘要
A system for measuring the open space between, and the ratio of open space to cord diameter, of cord reinforced tyre fabric. A collimated X-ray source and detector scan across the tyre fabric as it is calendered providing a signal corresponding to each edge of a cord. A counter counting at a constant rate provides a time interval measurement of each open space, and also of the corresponding open space plus cord, as the X-ray source and detector scans the fabric. The quotient of the two time intervals determined is proportional to the fractional open space at a particular location in the fabric. An alarm is provided to indicate when the open space is outside predetermined limits.
