The device (22) has a feeder part arranged in an interior of a conveyor device. A swivel bearing (15) supports the feeder part on a control shaft. A first fastening section (16) is assigned to the swivel bearing. A second fastening section (18) i.e. annular disk, is arranged at distance from the first fastening-section. A predetermined breaking point (21) between the fastening sections is arranged on the feeder part. The first fastening section and the second fastening section are interconnected by a resiliently elastic connecting element (17) i.e. helical tension spring (24).
