ABSTRACT:
A pattern monitoring method and apparatus wherein the movements of each individual yarn are detected and recorded. A piece of textile goods is produced, and all the yarn movements for making that piece are recorded, that record being then used as a standard. Additional pieces are made, and the yarn movements during the making of the additional pieces are detected and similarly recorded. The movements may, immediately or eventually be compared to the standard. An error signal is given when there is no match; however, an allowable error can be selected so that the error signal is given only when the error is greater than the selected allowable error. The error signal can be a light, or may be a stop motion device.
