For some time now Marbach has been offering pure edge technology for achieving clean visible edges in corrugated board. Many customers are now using pure edge. It has been shown that this technology not only provides clean visible edges for corrugated board packaging, but is able to do much more.
Marbach developer Ingo Graham: "pure edge ensures clean visible edges for corrugated board packaging. We have known this for a long time. The success of pure edge and the feedback from our customers confirm this. Since we are enthusiastic about the technology ourselves, we have tested it on other applications. We have discovered that it is very versatile."
Knife protection in the edge area
The material to be cut often pushes the long straight edge knives away during the die-cutting process. The effect: due to the lateral material displacement, the cutting rule tip wears out relatively quickly at these points. This impacts the quality of the die-cutting result. The use of pure edge on both sides protects and stabilizes the cutting rules at the edges. The lifespan of the tool is thus extended and the cutting result significantly improved.
Stabilization of rule joints
In two-sided circumferential die-cutting, on narrow slots or on cutting contours, it is possible that the material which is being die-cut may squeeze the rules apart. This results in unwanted nicks. By using pure edge this can be prevented and the rule joints stabilized.
Increased service life
Pure edge can be used as a complete replacement of functional rubbering. Conventional functional rubber absorbs cutting pressure. In order to achieve good die-cutting results, this must be increased. But not with pure edge. Here the material is not unnecessarily tensioned and thus no additional cutting pressure is required. Pure edge should be used above all, in places where increased folding-spring-back forces in the material have to be avoided, but at the same time where no unnecessary traction forces should occur. As with 180-degree package folding, or nearby cut-crease rules for yoghurt crates with little surrounding material. But also on rules with transport nicks.
Solution for narrow areas
Depending on the requirements, pure edge is possible in widths ranging from 0.5 mm to 3.0 mm. This means that the technology can also be used in narrow places where there is simply no room for profile rubbering.
pure edge is made of steel. Compared to rubber, this is very wear-resistant and has an extremely long lifespan.
With pure edge, Marbach offers a technology that can be used in a variety of ways and which not only stands for attractive optical corrugated cardboard packaging, but also for long tool life.
Marbach is waiting for FachPack 2018 to start. On September 25, this important meeting place for the packaging industry will open its doors. More than 40,000 visitors are expected in Nuremberg during the three days of the fair. Marbach will present its innovations at booth 612 in hall 7. Marbach has additonally a stand at the special exhibition "Packaging in Medical Technology and Pharmacy" in Hall 3A where it will present its products for pharmaceutical manufacturers.
Marbach has recently been offering a new technology, which focuses on the embossing of small print runs. With its polymar embossing plates, Marbach has been offering a quickly available, and at the same time inexpensive solution for embossing small quantities. The first customer orders have already been produced and look very promising. A new technology with enormous potential.
Marbach Werkzeugbau invested in a Gabler M98 Maxx last year. This machine has in the meantime passed its test. Three tools were test-run for a US customer – all with great success.
Marbach regularly organizes what has become known as the Marbach Cup. At this football tournament, employees of the various Marbach subsidiaries from all over the world meet at different locations to test their football skills. In addition to the sporting part, there is always a leisure activity with sightseeing, and all in a relaxed get-together atmosphere. The Marbach Cup has existed now for more than a decade and the participants always look forward to meeting their colleagues from other countries. This year The Marbach Cup took place from July 6 to 8 in Russia. The venue was at the Marbach franchise partner Raster in Obninsk.
