Emhart Glass has launched a new generation of neck ring mechanisms, featuring closing forces increased by 20%, optimised airflow for improved synchronisation motion and a fine-thread screw for greater T-nut clamping force.

According to the company, the tapered pin assembly has been replaced with a strong, standardised retaining ring assembly.

The design is aimed at offering a higher clamping force for the neck ring holder arm, and opens up the possibility of higher revert speeds. It allows for balanced opening of right and left neck ring cylinders, leading to fewer finish checks.

It is fully interchangeable with existing mechanisms and old and new versions of the mechanism can be operated side-by-side on the same machine. However, many of the individual parts within the new mechanism are not compatible with earlier versions.
