UWS400SS Ultrasonic Cuff Sewing Machine

Principle

Ultrasonic welding machines of the UWS400SS series combine all the physical advantages of ultrasonic welding with the whole range of technological sewing experience. 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 UWS400SS 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 UWS400SS is the first choice.

Features

• Controled electronically (power. amplitude, speed and pressure)
• Seam distances resp operating cycles can be programmed
• Reproducbility of the welding process
• The energy adjusts to the speed (via a pedal), so that reliable dynamic welding
• Equpped with differential feed separate drive for sonotrode and anvil wheel thatmeans smooth, non-dstorted seams or the pssibility of adding a some fullness
• Process reliability through monitoring of welding parameters with integrated device tor constant peformance, so that reliable processing is pssible even when sewing over cross searms
• 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.
