Fixing elastic threads
Hygiene products for everyday use are adapted for various applications and requirements. The goal: To simplify everyday life. Product properties, such as skin friendliness, feel and functionality play an important role and are decisive in determining customer satisfaction. The bonding of nonwovens in the baby and incontinence segment is already implemented successfully using ultrasonics.
Comfort around the waist and on the leg cuffs can only be achieved using elastic threads or film. These fibers are still predominantly fixed using adhesive. We have continued to develop and perfect the adhesive-free alternative with ultrasonics.

How does our solution work?
Now it's time for your project.
Every project is unique. This is why we listen to you and together we develop a customized solution that fits your requirements exactly.
Elastic thread fixation without additional adhesive
- Maximum energy efficiency
- 0% adhesive
- Rejection rate reduced by 30%
Elastic threads are used to achieve better physical comfort in the waist and leg areas when producing diapers. It is predominantly allergenic adhesives which are used to fix these threads.
Ultrasonics are the sustainable alternative: No chemicals, no adhesives, and a reduction of the share of thermoplastic materials in the product composition.
As well as leaving out additional adhesives, we can also join new, environmentally friendly materials together. In our high-tech laboratories, we find optimum joining solutions for recyclable, organically-based, and biodegradable nonwovens. Let us help you get your diaper production ready for the future.
Consistently high-quality elastic fixing
- 80% less down time
- Flexible material and fiber combinations
- Patented technology
Handling and fixing elastic threads can be complicated and costly when manufacturing hygiene products. This is why we have developed an innovative new process for fixing elastic threads. Simple fiber handling, reduced risk of breakage and an enlarged process window are just of a few of the advantages.
The patented Herrmann sonotrode, specially designed for elastic fixation, positions the elastic threads perfectly on the nonwovens. A wide variety of material combinations, different fibers, stretches and speeds can be processed safely and quickly with this novel technology.
We are unique on the market, and we can guarantee consistent weld results at a low setup cost.
Supple and sturdy with elastic threads
- 100% soft
- Very comfortable to wear
- Secure leak protection
A firm shape, soft edges and maximum layer adhesion for premium quality products ensure excellent comfort when the product is worn, and a great feel on the skin. Free from any additives, the nonwovens remain soft, smooth and the surface is intact.
Elastic threads give nonwovens a new shape and function. Diapers are fitted with these, particularly in the leg cuff and waistband.
Joining using ultrasonics guarantees the ideal stretch behavior and thus also the perfect fit. As the elastic threads are not heated during the joining process, the product retains its complete stretchability.
We can guarantee the best possible feel for your product. Even for joining natural fibers and recyclable or compostable materials.
