USM450S Ultrasonic Cuff Sewing Machine

Principle

Ultrasonic welding machines of the USM450S series combine all the physical advantages of ultrasonic welding with the whole range of technological sewing experience. The workpiece is held between the ultrasonic generator 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 USM450S 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 USM450S is the first choice.

Features

• Controlled electronically (power. amplitude, speed and pressure)
• Seam distances resp operating cycles can be programmed
• Reproducibility of the welding process
• The energy adjusts to the speed (via a pedal), so that reliable dynamic welding
• Equipped with differential feed separate drive for ultrasonic generator and anvil wheel that means smooth, non-distorted seams or the possibility of adding a some fullness
• Process reliability through monitoring of welding parameters with integrated device tor constant performance, so that reliable processing is possible even when sewing over cross seams
• Possibility of spot welding (tacking)
• No start/stop – marks
• Touch screen (simple handling with pictograms).

Application

The version is used to weld a seam or hem at the end of sleeves or tubes. In addition, it is particularly suited for welding bottoms in tubes and containers, as well as for welding annular seams on hoses.
