The apparatus is provided with separating means (7) for separating feed from a bale which is disposed at the discharge side (6) of a conveyor alley. In one embodiment the conveyor alleys (2) are each provided with their own individual separating element (7) which can be moved by way of a fixed, unmovable guide (8) along the width of the discharge side. In another embodiment the guide frame (39, 50, 73) is arranged such as to enable the separating element (25, 35, 45, 75) to be guided along several conveyor alleys in a single cutting path.
