ROPP Capping Machines - ROPP Cappers

ROPP Capping Head Forms Threads to Conform to Bottle Threading from outside the shell

Many customers ask us what ROPP is and the simple answer is Roll On Pilfer Proof closure.  Simply put it is an unthreaded aluminum shell that is placed on and pressed down onto the bottle neck while thread forming wheels spin around the shell and press against it to conform to the existing threads of the bottle and locking ring. In many respects a ROPP capper resembles a chuck capper although since it is not torquing a cap there is no clutch mechanism required.  ROPP capping machines are available  as a single head to multiple head high speed rotary systems. The big advantage of a ROPP capper machine is that it is sealing the product at the same time it is providing tamper evident security. The big disadvantage is that it is expensive to run more than one size cap. The neck and threads of the bottle must also be hard enough to withstand the pressure required to form threads such as glass or hard plastic.

Rotary ROPP capping equipment is available from 4 to as many heads as needed to meet the production requirements.  A ROPP rotary capping machine can be a stand-alone machine or integrated into a Dual-Modal or Tri-Modal filling, capping and rinsing monoblock.  We highly recommend sizing all bottle neck finishes that are planned to be filled be one size only as changeover times and cost of change parts increase with the size of the machine.

We highly recommend you call us to discuss your product and productions requirements to configure the best system for you.  Call 800-840-9573 (USA) or 520-777-3360 (Intl).


Oftentimes ROPP Cappers are incorporated into large monoblock systems for Rinsing, Filling and Capping
