  • Patent number: 6935090
    Abstract: 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.

  • Patent number: 6591585
    Abstract: A forming roller for manufacturing moulded bodies with the rotary die method comprises a surface which is roughened at least in the region of the forming roller webs. By way of the roughening of the forming roller webs the adhesive friction for the material tapes from which the moulded bodies are manufactured is increased. The roughness of the surface parts of the forming roller is advantageously produced by the processing of the surface with a blast means.
