Case Study
IMPRESSIVE INTERACTION OF TECHNOLOGY Bobst’s ongoing development of technology and consistent focus on new requirements are reflected in various components of the EXPERTFOLD 165. For example, the smooth and precise feeding of blanks with the integrated ACCUFEED alignment module contributes significantly to the high reliability in the production of medium-sized e-commerce packaging. With its wider infeed transport, the alignment module guarantees highest folding quality even with heavier materials. Mr Würth says: “We generally insert our die- cut blanks in a straight line. ACCUFEED ideally supports the smooth feeding of the blanks and their insertion into the EXPERTFOLD 165.” From his point of view, the transport belts are optimally designed for processing corrugated board. The technology for applying silicone strips and self-adhesive tapes is seamlessly integrated thanks to the special POLYVACUUM module. This not only reduces manufacturing costs, but also simplifies production.
For quality assurance, the individual machine modules are equipped with sensors, which measure the lengths of the boxes and stop the machine if any deviations from the specified parameters are detected.
The control system will indicate on the screen which sensor has triggered the stop, so the operators can quickly eliminate the cause of the problem. In short, the entire technology works together smoothly.
The delivery, which has been specially configured for the production of e-commerce packaging, also fits into this picture. Thanks to its sophisticated technology with separate drive and automatic apron centering, the finished boxes are delivered on the belt aligned perfectly straight.
FAST CHANGEOVERS
Wellstar usually produces order sizes of between about 2,000 and 50,000 in a two-shift operation on the EXPERTFOLD 165, with about four job changeovers per day currently.
As a folder-gluer of the latest generation, the EXPERTFOLD 165 offers even greater ease of operation. For example, all sections have been equipped with individual command panels to shorten the distances for machine operators and enable them to react as quickly as possible. “This means that our operators do not have to rely entirely on the remote control,” says Mr Würth. In addition, they can adjust the transport here via toggle switches without having to navigate through the menu on their remote controls. The infeed transports of the EXPERTFOLD 165 can also be automatically locked and unlocked via a toggle switch, which on its own reduces makeready

Being able to cover the market’s requirements as completely as possible from a single source is the company’s philosophy.
times by up to five minutes.
“The machine’s ease of operation has been very well received by our machine operators. They really enjoy working on the new folder-gluer,” says Mr Würth.
Wellstar stores all job data, including the positions of the transports, in the machine’s MATIC control system. For repeat orders, these can be retrieved at the simple touch of a button. In view of the many long-term relationships with customers, the proportion of repeat orders at the company is comparatively high.
ALL FROM ONE SINGLE SOURCE
“The EXPERTFOLD 165 makes it even easier for us to achieve the high quality we strive for in our e-commerce packaging,” says Mr Würth. At the same time, its ease of operation and the quick intervention of the machine operators in the event of a malfunction have further minimised waste, which is recycled back into corrugated
“No matter what formats our customers require and whether they need printed or unprinted packaging, there is hardly anything we cannot do for the corrugated board sector,” says Mr Würth. In addition to bespoke packaging, the company offers around 350 different standard products, which it ships from stock to anywhere in Germany with the shortest delivery times. Some of these can be ordered via its online store
verpackungenbestellen.de. In addition, customers can customise shipping packaging for delivery throughout Europe on the
PrintYourBox.de website.
“Bobst will continue to develop its technology and the company responds quickly and proactively to new market requirements. That is unmistakable,” says Mr Würth. With its cornerstones of digitalisation, automation, connectivity and sustainability, Bobst’s vision for the future sets the tone. For example, Wellstar now uses the convenience of the myBobst online portal to quickly procure spare parts for its folder-gluers. The new European spare parts warehouse in Genk, Belgium, will further improve availability.
