ABSTRACT:
An apparatus for delooping fibers in a fluid flow preferably includes a cyclone for receiving entities from a fiber individualizer and delivering individual fibers to a sensor. The fluid flow rate to the cyclone is set to optimize operation of the individualizer and the flow rate from the cyclone is set to optimize operation of the sensor. A nozzle is provided in the sensor for mechanically delooping the fibers so they are sensed in a straight condition. In addition, electronics associated with the sensor detects sensor signals corresponding to looped fibers and electronically "deloops" the fibers to produce data, such as the actual length of a fiber that was presented to the sensor in a looped condition.
