Continuous ultrasonic welding

With our ultrasonic technology we offer you processes for the continuous joining, welding, laminating, embossing, cutting of nonwovens, textiles, and plastics. Among other things, the products and systems of Hermann Ultraschall are used for high-volume production in the textiles, medical, hygiene, filter, and general technical industries. Customers appreciate the consistently high-quality and controlled weld quality at high speeds. This allows the realization of complex applications with user-friendly, very simple handling.

Basic knowledge: Laminating nonwovens and web materials

The general principle of ultrasonic welding can also be applied to nonwovens. The thermoplastic fibers are activated by mechanical vibrations thus melting and bonding in pre-defined patterns. Under what conditions is ultrasonic joining suitable for nonwovens? More basic knowledge on laminating of nonwovens and examples for applications, as well as an overview of various weld geometries is available here. Basic knowledge

Core Applications

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.

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.

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.

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.

PERFORATING: Defined perforation of films and silicone layers by means of ultrasonics and an anvil drum. This ensures an increase in process speed compared to thermal processes, without any negative influence on the material.

CUTTING: Cutting and simultaneous sealing of nonwovens in one single process ensures fiber-free joining of marginal areas. This technology is also used for splicing of material webs so that the joining point quality is suitable for end products.
