Automatic Ropp Capping Machine

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.

The machine can be equipped with different types of cap unscrambler (vibrating, rotary, belt type) depending on the type and size of the cap. For feeding the caps into the cap unscrambler the caps hopper is available.

For placing difficult caps onto the container neck the “Pick and Place” system can be used.

ROPP CAPPING MACHINE Working Function:

The containers are transferred to the star wheel by means of the conveyor. The star wheel (indexing type for one-head capper or continuous motion for multiple-head capper) takes the containers and carries them to the caps placing station and than to the closing head. The closing head tightens the cap with the necessary torque (if the head is of the pressure type, it will press the cap on the bottle neck by means of a spring unit). The torque can be set on the closing head by means of magnetic clutch. After completion of the closing process, the star wheel moves the container to next station for press the black small cap, after that the star wheel moves the container to the finish products conveyor.
