This invention concerns a device for transporting a strand (12) of carrier material which is connected, at least on one side, to individual chambers (6) made of filter paper material, spaced apart, following one after another, closed on all sides, containing a quantity of substance and composed of a strip of carrier material, with at least two independently driven belts (2, 3), one segment of which runs at least partly parallel to the strand (12) of carrier material and having cams (4, 5) spaced apart on the side facing the strand (12) of carrier material, whereby they grasp the strand (12) of carrier material between the chambers (6) and/or in the area where one chamber (6) is connected to the strand (12) of carrier material, working along with a support, and transport it with the movement of the belts.
