INDUCTIVELY POWERED ILLUMINATION SYSTEM FOR TUBULAR FABRIC

摘要

An illumination system for tubular fabric of indeterminate length such as knitted tubular fabric produced by a circular knit textile machine which includes a light source supported in a floating manner inside continuously advancing tubular fabric together with a receiving antenna connected thereto and a transmitter having a transmitting antenna outside the fabric by means of which a beam of high radio frequency energy is transmitted through the fabric to the receiving antenna for energizing the light source and thereby providing illumination behind the wall of the fabric to facilitate visual observation of the advancing fabric for the detection of imperfections and the like.
