Abstract
The presence of extraneous materials such as polypropylene strings or strands in textile fiber material is detected at the bale shaver or plucker in which tufts of the textile fiber are removed from the bale by a rotary plucker head. The plucker head is received in a suction removal hood so that a strand which tends to be wound on the head will impact upon the hood and the frequency of such impact is automatically detected and, if found to be related to the frequency of rotation of the head, automatically causes shut down of the machine to enable clearing of the extraneous fiber or string from the head.
