PFAFF 8301
Ultrasonic welding machines of the Seamsonic series combine all the physical advantages of ultrasonic welding with the whole range of technological sewing experience. On the PFAFF 8301/8310/8312 Seamsonic the workpiece is held between the sonotrode and the anvil wheel and welded continuously under pressure. When welding continuously by the ultrasonic method, the material to be welded will be subjected to rapid changing pressure vibrations. The heat develops because of molecular vibrations beneath the material surface, for thin materials within the immediate vicinity of the actual weld.

Ultrasonic welding with the Seamsonic is a modern, innovative and economic alternative and complementary to conventional sewing technology. If assembling of laminates, clothing fabrics with high share of polymer and technical nonwovens is required and in particular to get, the use of the Seamsonic is the first choice.

Version PFAFF 8301 CS / cut&seal

The proved single-wheel solution was optimized by the use of steel-sonotrode. This will reduce wear and associated costs greatly. For our customers the fine C&S-seam with its high strength is the main argument to buy this class of machines.
Anwendung Cut&Seal

Version PFAFF 8301 CS / cut&seal DUAL

This solution features two anvil wheels (one for cutting and sealing and the other one to realize the second weld seam) on one post, but on separate shafts. With this patented solution the load may be individually adjusted – the two wheels are still running in sync. This is an absolute unique selling point (USP) for this technology. The machine may be adjusted better and more specifically to the material at hand and increases the process reliability when welding and cutting to weld seams. The minimum distance between weld seam an cutting is around 1 mm.
