An apparatus for the conditioning in envelopes of individual dual-use filter sachets, obtained from a flattened tube of thermally weldable filter paper, having multiple bags or pouches defined by transverse thermal welds in continuous production machines, with labels, thread and fastening tabs for same, cutting the tube into portions comprising at least two pouches across the fastening tabs, folding the portions in fan-shape along the intermediate transverse thermal weld and setting up these pouches adjacent to each other for joining the corresponding adjacent extremities. Such an apparatus has a device for feeding portions of packing paper located underneath said multiple pouches folded into fanshape between the folding and transfer unit capable of transferring the pouches through a fixed folder effecting a U-shaped fold between the prongs of pincers of an intermittently rotating pincer wheel for joining the aforesaid adjacent extremities and for peripherally sealing the envelope enclosing the sachet.
