Abstract:
1. A tablet press machine ( 1 ) of the type with a rotary turret ( 3 ) for the production of tablets, comprising a hopper ( 2 ) containing pharmaceutical product in powder or granular form to be compressed; a rotary disc ( 4 ) equipped with matrices ( 5 ) designed to contain defined quantities of the pharmaceutical product fed to them by the hopper ( 2 ); reciprocating punches ( 8 , 9 ) for compressing the powdered product and constituting a plurality of compressing operating stations ( 10 ); the machine being characterised in that said-plurality of stations ( 10 ) comprises at least one set (A) of operating stations ( 10 a ) having a modified structure to inhibit operation, each station ( 10 a ) with a modified structure comprising barrier means ( 11 ) designed to be fitted at the matrices ( 5 ) in such a way as to prevent the passage of the product from the hopper ( 2 ) to the matrices ( 5 ), and opposing spring means ( 12 ) designed to be coupled to, and act in conjunction with, the reciprocating punches ( 8 , 9 ) and with the barrier means ( 11 ) in order to simulate the presence of the powdered product.
