Hepcomotion’s PRT2 precision ring track system has allowed designers at A B Graphic, a manufacturer of label converting and finishing machinery, to create a more cost-efficient mechanism for its new turret rewinder module.

A B Graphic specialises in fully modular digital converting, inspection and turret rewinding. It also produces machines for many specialist applications, including RFID insertion, laser die cutting, booklet labelling and camera inspection.

The machine range for which the turret rewinder was developed is the Digicon Series 2, whose modular construction allows each machine to be custom built.

The turret option enables the non-stop rewinding of label rolls at the end of the finishing processes. It automatically cuts the material and reapplies it to the new rewind mandrel.

The role of the Hepcomotion PRT2 is to carry two mandrels that are mounted on the ring. When one mandrel is full, the turret rotates 180º so the next mandrel can be rewound.

Key benefits of product application

  • A B Graphic specified the PRT2 with a gear-cut option as it provides an easy means of direct driving on the circumference of the turret disc.
  • The PRT2 second-generation continuous motion system provides a wide choice of components, sizes and options.
  • Elements from Hepcomotion’s PRT2 range create a limitless variation of open paths and closed circuits.
  • As the PRT2 supports the disc around the circumference, it leaves a hollow centre that accommodates the rewind drive input and air supply to the mandrels. 
  • According to A B Graphic’s Mike Adams, the new mechanism requires less structural support and mounting the turret disc accurately to the machine faceplate is straightforward.

Designing a unique engineering principle and making it a commercial success is quite an accomplishment.  Developing that concept and embracing complementary technologies to the point where the business becomes a world leader in its field takes that achievement into a different league.  HepcoMotion has achieved both and in 2009 celebrates 40th year of trading.   

Today HepcoMotion is one of the world’s foremost innovators and manufacturers of linear motion technology.  And this can be attributed to the important tenet – continued investment in its people processes and products.  This has allowed the company to grow even at times of economical difficulty.  

Although its range of individual, linear motion products remains an important part of its business the growth area for HepcoMotion in recent years is in specials and assemblies.  Almost one fifth of its shop floor space is devoted to assembly and the company has invested heavily in flexible manufacturing to ensure that even last minute changes can be accommodated to customer specification.  

Constantly re-assessing its strengths against changing market demands continues to provide HepcoMotion with the momentum for business growth.  The culture of ongoing investment has certainly worked well throughout its first 40 years and will continue to underpin its business in the decades to come.
