Abstract

An apron drafting system for a spinning machine, in particular an air spinning machine, with a bottom apron guided over a drivable bottom roller, the bottom apron being supported in the area of a drawing zone, in particular a main drawing zone, by a sliding section of an apron bridge. In order to provide an apron drafting system in which reliable guidance of the bottom apron is ensured while maintaining a high drive power, there is provision for the apron bridge for guiding the bottom apron to have a line section with guiding means for lateral guidance of the bottom apron circulating around the apron bridge.
