Impurity-removal device for an open-end spinning machine

摘要

An open-end spinning machine (1) with a plurality of adjacent open-end spinning units (2) each having a sliver opening device (4) with impurity-discharge openings (10). An impurity-removal device (11) is installed below the impurity-discharge openings (10) and comprises an impurity-removal belt (12) which can be driven in a reciprocating manner. A cleaning carriage (16) is arranged on the impurity-removal belt (12) and is connected by frictional engagement to the impurity-removal belt (12). The cleaning carriage (16) has a cleaning lip (18) which mechanically cleans the areas of the sliver opening devices (4) especially endangered by contamination. The cleaning carriage (12) can be shifted as required relative to the impurity-removal belt (12).
