Graphic Paper Machines
The range of use of graphic papers
For hundreds of years, graphic paper has been a carrier of information. Voith's high-speed machines make it a global leader, especially in the area of newsprint and magazine paper.
For centuries, the great merit of graphic paper as a carrier of information has been as a storage medium for knowledge. All information is valuable, no doubt, but the paper on which it is printed can sometimes vary greatly.
From newspaper to high-gloss magazine
As a rule, mass products such as newsprint are produced with a large portion of recovered paper, often due to their short-lived topicality and for reasons of cost. By contrast, magazine paper has high requirements regarding appearance, both visual and sometimes even tactile. For this reason, the portion of fresh fibers in the paper suspension usually predominates. But more and more frequently, such high-quality paper is being produced with a large portion of recovered paper. Voith’s deinking technology plays a big role here: The raw material for new paper can be provided from recovered paper in the thousands of tons.

During rewinding, the paper web is wound up on reel spools, which are changed fully automatically every 60 to 90 minutes after reaching the full diameter of the paper roll. The inner layers on the new reel spool are exposed to very high stresses and therefore are vulnerable to damages. Typical damages are wrinkles and core bursts, but also glossy spots on matt paper can occur. Our reeling systems optimally control roll structure and roll hardness – from the first to the last layer.
Voith offers reeling concepts for all paper grades that fully meet all requirements with regard to winding quality and cost-effectiveness.read more
