Patent ID: 8291680

Claim:
Method for processing container closures ( 2 ), comprising the following steps: sterilizing the closures ( 2 ) by spraying on the closures ( 2 ) a hot sterilization fluid; transferring the closures ( 2 ) from a sterilization unit ( 3 ) to a capping unit ( 4 ), by means of a guide member ( 5 ) interposed therein; screwing the closures ( 2 ) for connecting them on correspondent containers, applying a predetermined torque to the closures ( 2 ) in the capping unit ( 4 ), characterized in that it comprises: a step of regulating the temperature of the closures ( 2 ) fed to the capping unit ( 4 ) arranged in the guide member ( 5 ), to provide that the closures ( 2 ) have a predetermined desired temperature in the capping unit ( 4 ), the regulating step being a step of heating the closures ( 2 ) arranged in the guide member ( 5 ); a step of sensing the transit of the closures ( 2 ) towards the capping unit ( 4 ), an activation of the heating step being triggered when the transit of the closures ( 2 ) is interrupted.
