From the Sector

The MS Ultrasonic Technology Group is a globally recognized technology and innovation leader in ultrasonic joining technology and develops and builds flexible special machines, pioneering series machines, modular systems and efficient components for high-performance complete solutions.

This enables optimal welding, punching, sealing, cut-off welding and riveting of thermoplastics, textiles and nonwovens as well as cutting of food and other products.

To ensure sustainable growth, MS is focusing on expanding its application portfolio and entering new market segments. MS Ultrasonic Technology Group is part of the listed MS Industrie AG with internationally active companies.

In addition to the company's previous activities, MS is now placing a new focus on the continuous welding of nonwovens and other materials.

More than 30 years of experience in the development and production of high-quality and innovative ultrasonic components, coupled with know-how in drive and control technology, will be incorporated into the new business segment. This means that customers receive ready-to-integrate systems with maximum precision from a single source. With the new MS Competence Center in Ettlingen (Germany), MS is fulfilling the wish of many customers to expand its application portfolio to include continuous joining, embossing and perforating of nonwovens and sealing of packaging.

MS is thus adding an innovative and specialized site, while maintaining a high level of vertical integration and support for all specialist areas through its main site in Spaichingen (Germany). In two application laboratories and a measurement and analysis laboratory, tests, evaluations and optimizations of various welding tasks are just as much a part of the service as the in-house production of engraving rollers through to complete systems.

• Application engineering consulting for your welding task
• Support in the design of the engraving roll
• Execution of feasibility studies
• Welding tests to determine the process parameters
• Individualized process optimization
• Finding solutions for problematic welding applications
• Testing of quality-describing characteristics (tightness, porosity, strength)
• Microscopic analysis of the welded joint in 3D
• Sample creation and pre-series production

Wülfing GmbH is one of the oldest but also one of the most modern home textiles companies in Germany, with its main weaving and finishing operations located in Borken, North Rhine-Westphalia, and a further jacquard weaving mill in Steinfurt, as well as with a making up and packaging plant in the Czech Republic.

At its Borken plant, Wülfing has employed a Monforts sanforizing line since 2009 to guarantee the required dimensional stability and shrink-fastness of its high quality bed linen. With a working width of over three metres, the sanforizing process is a central pillar in the production of typical wide-width cotton fabrics for home textiles.

In 2017, the company was able to acquire a second Monforts sanforizing line from another company which, although built in 2005, had been virtually unused. It was overhauled and installed behind a Monforts equalizing frame of a similar age.

“Unfortunately, the two machines had to be operated separately via individual controls and did not represent an integrated unit,” says Schulte-Mesum. “This resulted in deficits in the desired productivity and in the control technology.”

Wülfing consulted with Monforts on a number of upgrade options and opted for a completely new joint control system to merge the two machines, as well as a new connecting inlet, a tensioning and damping field and a steaming unit.

“Monforts provided a fast and precise erection and commissioning of the technology in spite of the difficult pandemic circumstances,” says Schulte-Mesum. “The result has been an increase in production speeds by 20% and enhanced uniformity in fabric width through a much improved guidance system.

“We are also achieving energy savings as a result of the new control and drive technology and operation has been simplified and improved as a result of the unified control. We benefit from simplified access for maintenance work such as the grinding of the rubber blanket, but most of all we have greatly improved our flexibility and now have two almost identical Monforts sanforizing lines.”
