ABSTRACT:
A filling machine for thermoplastic cups, with a cyclically operating conveying section which takes over a cup sheet web with thermoformed cups from a thermoforming station, there being provided, for the simultaneous filling of a batch of cups, for each cup of the batch, a filling unit with a filling cylinder and a filling pipe for a pasty filling product, the filling cylinder containing a filling piston on the product side. The technical problem is to provide a filling machine which is easily adjustable in terms of volume, works without a sucking action, and is easy to clean and sterilize. An air piston (31) is connected, on the drive side, to the filling piston (24) by a piston rod (40) and the filling cylinder (23) is closed off above the air piston (31) by a cylinder head (32) which is connected to a pressure compensation reservoir via a compensation pipe (35).
