Abstract
A method for sorting tablets at a rotary press for making tablets, comprising the following steps: the individual tablets are monitored with regard to at least one property of their condition during the pressing process, and a bad-signal is generated, if a tablet does not fulfill the property, and tablets which do not generate a bad-signal being good-tablets; the good-tablets are directed from a die plate of the rotary press into a good-channel; after a bad-signal has been generated, a bad-tablet is directed into a bad-channel by means of an air blast; by means of a further air stream, which is directed into the bad-channel, the bad-tablet is accelerated into the bad-channel whereby a returning to the die plate is avoided.
