67—THE GUELPH INTEGRATOR AND ITS USE IN TESTING SHORT-TERM YARN IRREGULARITY

A description is given of a new integrator, based on the principle of the Miller sweep and developed specifically for textile applications, though ready adaptability to other uses is a simple matter. The basic principles of operation are described, the calibration and operating procedures are outlined, and an indication of the way in which the integrator may be used in yarn-irregularity computation is given. The requirements of a commercial integrator using the same principle are also put forward.
