Our solutions
Welding / longitudinal seal
When welding nonwovens in combination with longitudinal seals, high-strength connections are established at the joint areas. Rotary ultrasonic systems are particularly suitable for joining applications in marginal areas.
Benefits / special features: Additional web material transport
Fast processing
Tight and strong connection
Welding / cross seal
When welding cross seals, instantaneous peak power must be precisely controlled and introduced into the joint areas in a minimum of time. For such applications, correct selection of the anvil geometry and the ultrasonic system is of particular importance.
Benefits / special features:
Consistent and uniformly strong connection
High product throughput per minute
Soft hand feel
Laminating
Targeted joining of several layers of nonwovens by means of ultrasonics and an anvil drum with structure. Bonding of the material web is merely performed in “spots”, which prevents any adverse effects e.g. on filter properties or stretching behavior of elastic composites.
Benefits / special features:
Energy-saving
No adhesives required
Fast processing
Embossing
With an engraved anvil drum a pattern structure is permanently embossed onto a textile surface through application of pressure. During this process additional design effects may be achieved, depending on color combinations of the material layers to be embossed.
