METHOD AND DEVICE FOR REPLACING CONVENTIONAL BOTTLE STOPPER FITTING MACHINE BY REMOVABLE LIGHT METAL COVER FITTING MACHINE

摘要

A method and apparatus for converting conventional bottle crowning machines for the proper application of lighweight metal tear off closures. The standard crowner mechanism is detached from the free end of a work imparting shaft mounted for vertical reciprocation along its longitudinal axis. A tear off closure applying head is installed in place of the crowner mechanism with a self-contained compensating spring unit interposed axially between the shaft end and the applying head. The converted machine is capable of uniformly applying tear off closures with adequate compensation for normal dimensional variations in the bottles being capped.
