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 already involved in its planning for the most important international trade fair for the printing industry: drupa 2020. And now there is only 1 year left until drupa opens its doors again. The last drupa was very special for Marbach: with the number of visitors reaching record levels. No previous drupa had more visitors at the Marbach stand than in 2016.
Marbach has continuously expanded its services in the past year. The newest member of the Marbach service family is the Marbach Performance Boost package. By which, Marbach supports its consulting service which makes its own process know-how available to its customers and thereby significantly increasing their productivity during the die-cutting process.
Marbach has been using for some time now a new rubber for rubbering cutting-dies. The name of this high-performance material is flexpower. Certified by ISEGA for use in the food industry, this rubber offers numerous advantages to operators. Marbach uses flexpower in corrugated board tools (both flat and rotary) and also sells it as raw material.
Marbach is one of the large material suppliers in Germany. Under the name Marbach Die Supplies, Marbach offers materials for packaging manufacturers that meet the requirements in the field of die-cutting. In order to support its customers even more in increasing their performance, Marbach has expanded its material portfolio.
