During the formation of a container (C) from a blank, a pair of opposite end tabs of the partially erected container travelling on a conveyor (2) are closed against side walls at the front and rear of the container in the direction of travel by presser devices (18, 20) travelling with the container on their own conveying means (14a, 14b). The front and rear presser devices (18, 20) are mounted on separate units of the conveying means. The respective units can be driven at different speeds and are controlled so as to open the spacing between the presser devices at entry to and exit from the conveyor path and to close said spacing between said entry and exit to clamp the container tabs against said side walls. |
