<p>The procedure, e.g. for filling multipacks of plastic pots in a form-fill-seal operation, uses a dosing head capable of simultaneous or sequential dosing of quantities of the same or different viscous products in a coaxial, co-lateral or superimposed state, with one or other of the products containing pieces of a more solid material such as vegetables or fruit. In one version the head (3) has feed ducts (1, 2) for different products (A, B), controlled by elastic membranes (7, 10) actuated pneumatically by air fed through channels (8, 11). The products pass through channels (12, 13) in a nozzle (4) into a container (5).</p> |
