Pfaff 8311

This technology is also known as bonding and ensures a perfect connection of layers.

Ultrasonic machine for welding flexible thermoplastics and nonwoven fabrics.

Wide range of applications, from welding technical textiles to garment production or underwear.

The material to be welded is placed between the sonotrode and the anvil roller lowered from above.

Under automatically regulated pressure and the mutual rotation of the anvil roller and sonotrode, the material is continuously welded.

To assist in material extraction, the machine can be equipped with a puller roller.

Speed, amplitude, and pressure are automatically controlled.

The table is available in a flat version – tabletop version.

The anvil roller can be easily replaced without expert intervention.

The machine is equipped with a steel sonotrode for the possibility of welding and simultaneously trimming excess edges.

Excellent weldability of almost all thermoplastic films, laminates, textile materials with polymer content of 70% or more, and nonwoven fabrics.

High welding speed.

Seamless welding of small sharp curves and shapes.

Seams are flat.

No toxic fumes during welding.

No burnt spots during stops in the welding process.

Low energy consumption.

No consumables such as threads or needles.

Depending on the material used, it is possible to create waterproof and airtight seams.
