- means cooperating with said housing for combing a sliver into individual fibers and feeding said fibers along a path to said rotary spinning chamber;
- means communicating with said path for continuously removing dirt from said fibers during the operation of said combing means, said dirt removing means comprising:
- a dirt discharge opening in said housing communicating with said path;
- a dirt collection chamber positioned to receive therein dirt passing through said discharge opening;
- an air inlet and an air outlet opening into said dirt collection chamber;
