The filling wedge ( 4 ) with its preferably concave wedge surfaces ( 12, 12 ') is provided with feed channels ( 5 ) and preferably with a heating device ( 13 ) for heating up the wedge surfaces. To prevent heat-sensitive filling material from being heated up when it is passed through the filling wedge, arranged between the feed channels and the wedge surfaces is a means reducing the heat transfer, preferably in the form of a respective cooling channel ( 8, 8 '). Consequently, a thermal separation is achieved in the filling wedge between the feed channels and the wedge surfaces, which makes it possible to work with high operating temperatures for the capsule shell material. Such high temperatures are required, for example, in the case of capsule shells of thermoplastic starch.
