APPARATUS FOR MAKING STRIPS OF COHERENT PACKETS CONTAINING GROUND COFFEE OR THE LIKE ABSTRACT OF THE DISCLOSURE A strip of coherent packets of compacted batches of ground coffee between two overlapping webs of water-permeable material is formed along the upper reach of an endless conveyor with plates having supporting surfaces facing upwardly during travel along the upper reach and provided with recesses which communicate with a suction generating device. The first web is deposited onto the supporting surfaces of successive plates at a first station, followed by deformation of the web at a second station to form therein pockets which extend into the respective recesses and receive batches containing metered quantities of ground coffee at a third station. The batches are compacted in two stages to form cakes from which loose particles are sucked up by a nozzle before the second web is placed over the first web and the cakes. The two webs are then bonded to each other around the respective cakes, and the resulting packets are subjected to a quality control before the continuous strip of coherent packets is subdivided into lengths each of which contains a selected number of packets. The second compacting stage involves rotation of a tool relative to the batch therebelow so that the underside of the tool is free of particles of ground coffee when it is lifted above and away from the thus obtained cake.
