With technologies like Hyperpunch and Di-Lour needling, DiloGroup, Eberbach/Germany, belongs to the innovative machinery builders in the area of nonwovens.
The latest development in horizontal crosslappers, the “Hyperlayer” is now being installed in several spunlace production lines. This type of crosslapper can realize infeed speeds up to 200 m/min due to its special design and is ideal for a low number of layers of lightweight webs.
The Dilo “Hypertex” installation, consisting of a yarn laydown unit from Ontec Automation GmbH, Naila/Germany, and subsequent needling, provides highly efficient inline production of reinforced needlefelts. With this system, scrim structures and pre-needled web layers can be needled together at speeds up to 20 m/min.
The new needle arrangement “8000 X” ensures homogeneous distribution of needle penetrations in the felt over a wide range of advance/stroke. The results are considered a breakthrough for improved surface qualities, particularly for car interiors.
These innovations are only a part of the continuous development and refinement work for needling and spunlacing lines.
