| 摘要 |
The invention relates to a thermoforming machine for the production and filling of containers of thermoplastic film, with a plurality of workstations arranged in a row, which may include shaping, filling and sealing units for example, and these workstations are actuated by means of cam discs mounted on a drive shaft. To cut down undesired idle time when an exchange of cam discs (10) is unavoidable, a cam disc (10) is designed in a multi-part and dismountable fashion in such a way that it can be slid sideways onto a central drive shaft and fastened there. This is achieved by a recess (11), which connects the central hole (12) provided in the cam disc (10) for bearing purposes with the outer edge (13) of the cam disc (10). The recess (11) is bridged by a fitting piece (14) which can be screwed to the cam disc (10). <IMAGE>
