Precise Die Cutter Works Non-Stop On Cartons

The Krefeld plant of Freund has been using a Dymatrix 106 CSB die cutter from Heidelberg since last autumn.

The Krefeld plant of Freund has been using a Dymatrix 106 CSB die cutter from Heidelberg since last autumn.

Heidelberg unveiled the new cutter at Drupa 2004.

Freund opted for a complete packaging solution from Heidelberg comprising a Dymatrix 106 CSB, the recently installed Diana Pro 74 folder-gluer and two Speedmaster CD 102 presses.

The die-cutter processes sheet formats up to 76cm x 106cm (29.9" x 41.7") and die-cuts, embosses and creases paper of grammages 80gsm and above, board up to 2,000gsm and corrugated board up to 4mm thick at claimed speeds of up to 9,000 sheets per hour (sph) and with a cutting pressure of 330 tons said the company.

Heidelberg said that the Dymatrix 106 CSB uses standardised logistics systems to deliver an enhanced workflow.

"We are working non-stop with the same system pallets as in the printing press," explained Michael Raschke, production manager at Freund.

Non-stop pile changing in the feeder is followed by the cutting, stripping and blanking stations.

The die cutter is raised 90cm, like the press, in order to be able to use high pallets in non-stop operation added Heidelberg.

Raschke said he is delighted with the precision of the technology, not least the machines register accuracy.

The Dymatrix 106 CSB employs a moving upper platen.

According to Heidelberg, that method prevents the sheet moving vertically.

The fact that the material can travel through the machine smoothly maximises cutting quality, particularly with thinner materials.

Register systems, which achieve register accuracies of +/- 0.15mm (0.0059"), are present in all stations, such as the feeder, cutting, stripping and blanking units.

The Krefeld site of the Freund Group has a workforce of 70 producing folding cartons for automatic packaging machines, for example.

Its customers are midsize manufacturers of branded goods from the consumer goods and foodstuffs industries, at regional, national and international levels.

Heidelberg claimed that the Speedmaster CD 102 has increased printing capacity by 40 per cent.

The Freund Group has two further sites.

The Georgsmarienhutte site near Osnabruck, which is the company's headquarters, has a workforce of 144 and produces the packaging of laminated corrugated board and special packaging made of solid board.

The Dresden site has 26 employees producing product presentation displays.
