Nonwoven - Measuring systems and process control for non woven fabric

Solutions for the production, processing and finishing of non woven material

For the entire nonwoven sector - whether wet wipes, diaper components, non woven geotextiles or medical nonwoven - Mahlo supplies a quality control system that is tailored to the specific application and your individual measurement and control requirements.

Systems ranging from fixed measuring points to traversing measuring systems for single and double-sided measurement with several synchronized scanners are available.

Many of the renowned manufacturers of non woven fabric trust Mahlo’s long-lasting experience in on-line process monitoring and control technologies. Our expertise reaches back several decades, and we strive to improve ourselves every day anew, to optimise efficiency and quality of your production process.

Our experience in the non woven sector and corresponding understanding of process control enables Mahlo to tailor systems especially for the following nonwoven processes:

Airlaid / Dry Laid
Carded
Hydroentangled
Melt Blown

Needlepunched
Spunbond / SMS
Spunlaced
Wetlaid

Sensors

The right tool for every application

The Qualiscan QMS is a modular system consisting of multiple measuring sensors and measurement frames acting as intelligent nodes on a network. Some frames can run up to five Mahlo sensors at once, continuously, precisely and rapidly across the online product.

The versatile sensors and measuring devices of the Qualiscan QMS series can sense, log and continuously control such parameters as weight per unit area (basis weight), coating weight, thickness and moisture in a variety of web-type products.

Scanners

Universal application

The measuring frame traverses the sensors on-line across the whole product width and provides a cross-machine direction profile of basis weight, thickness or moisture on the display console that is a crosssection of the manufactured product.

One or more different measuring frames can be connected to a Qualiscan QMS system. Connection is made via a normal network cable, a standard 230/115 V source supplies the power.
