Abstract
A pneumatic debris aspirating device adapted to be retrofitted on open-end spinning frames originally designed for a mechanical debris disposal installation utilizes an asymmetrical debris pickup funnel which can be connected via a connector conduit to a source of suction which is part of the spinning mill. The debris aspirating device is embodied and disposed such that opening of a cover to each rotor spinning unit is not hampered.
