Abstract
A device for conveying a spring string (31) has a first spring conveyor (3) and a second spring conveyor (4). By means of a sensor device, in operation, lengths of a plurality of segments of the spring string differing from one another are detected, while the spring string (31) is guided past a sensor (5) of the sensor device arranged in the conveying direction upstream of the second spring conveyor (4). A control device (9) is provided which sets, in an operating state of the device (1) in which both the first spring conveyor (3) and the second spring conveyor (4) convey the spring string (31), time-sequentially a plurality of relative conveying speeds between a conveying speed of the second spring conveyor (4) and a conveying speed of the first spring conveyor (3), depending on the detected lengths.
