Patent ID: 7125234

Claim:
An apparatus comprising a set of compaction rams and dies for a rotary tabletting machine having at least one rotor that accommodates the set of compaction rams and at least one die plate that receives said dies in bores disposed thereabout, wherein at least one of the set of all compaction rams and all dies on the at least one die plate have a code containing at least the following information: (a) a label for the set of compaction rams and dies, (b) an individual label for each compaction ram and die within the set, (c) data effective to critically dimension the compaction ram and die which contains the code, and (d) data containing service life information for the compaction ram and die which contains the code, said apparatus further including a single reading head connected to a process computer of the tabletting machine via a signal cable, the single reading head being disposed within the tabletting machine and the code being located on the at least one of the set of all compaction rams and all dies in such a way that if the at least one rotor with the accommodated compaction rams and dies rotates about its axis all of the information in the code can be read from the compaction rams or dies.
