Abstract
This invention concerns a device for transporting a strand of carrier material which is connected, at least on one side, to individual chambers 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, one segment of which runs at least partly parallel to the strand of carrier material and having cams spaced apart on the side facing the strand of carrier material, whereby they grasp the strand of carrier material between the chambers and/or in the area where one chamber is connected to the strand of carrier material, working along with a support, and transport it with the movement of the belts.
