A sliver feeding device for an open-ended spinning machine (1) wherein sliver is fed to the front of a spinning rotor (44) revolving at high speed in a rotor housing (2), with a pivotable cover element (11) for closing the rotor housing (2) having an integrated sliver opening device (13) with a lateral sliver feeding device embodied as a feeding trough/condenser unit (17). An inlet condenser (28) of this feeding trough/condenser unit (17) has an open sliver guide chute (37) terminating in a condenser funnel (36). The sliver guide chute extends at a rearward inclination around a convexly rounded core area (39) of the inlet condenser. A sliver loop opener (23) is disconnected and arranged at a distance from the cover element (11) so as not to be affected by its pivotal opening movement.
