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 Werkzeugbau is looking forward to the upcoming K fair in Düsseldorf. This will take place from 16 to 23 October 2019. Marbach will be represented with a 94 m² stand and will present its new products to the visitors of this important plastics fair.
Marbach will take part in the Night of Apprenticeship in Heilbronn on the 26th of September 2019. On this day young people will be able to experience Marbach under the motto "Pack the world. With an apprenticeship at Marbach." Potential apprentices will be able to inform themselves about apprenticeships and studies offered at Marbach and also get to know the company.
Marbach is currently working intensively on the topics of digitalization and industry 4.0. Marbach is also focusing on the digitalization of industrial processes. One step resulting from this project is changing invoicing from postal to digital. As of 01 August 2019, the majority of german Marbach customers will receive their invoices by email.
In its Marbach Die Supplies & Automation division Marbach supplies machines, equipment and materials for die-making and printshops. With the robogrip, Marbach has a rule puller in its portfolio which proves itself to be an effective helper at the die-cutting machine.
