Abstract

A closure device (2) for closing a flexible container (4), in particular a valve bag (4), has a welding device (14), a sensor device (20) for acquiring a position of a part of the container (4) to be closed (6), and a control unit (28). The control unit (28) is coupled with the sensor device (20) and with the welding device (14), and is configured to place the welding device (14) in a first position and a second position spaced apart from the first position on the part of the container (4) to be closed (6) by actuating at least one moving device, to detect when at least one of the two positions has been reached via the sensor unit (20), and to actuate the welding device (14) at the respective first and second position to generate a weld seam on the container (4).
