The SeamMaster Ultrasonic Bonding machines manufactured by the Sonobond Ultrasonics, a leader in ultrasonic technology for nonwoven and woven synthetic materials have been awarded the trademark approval. The recognition is valid for the company’s complete line of ultrasonic equipment that bonds nonwoven and woven synthetic materials which include general purpose and high profile models, table-mounted cutter/sealer units, and modules for original equipment manufacturers.
Sonobond’s equipment uses ultrasonic vibrations to bond materials that are synthetic or blends containing up to 40% natural fibres like cotton. Sonobond’s SeamMaster Ultrasonic Sewing machines operate like traditional sewing machines with a continuous rotary operation, requiring minimal operator training. The machines use a patented rotary operation, where both horn and pattern wheel rotate at the same time to cut, sew and trim in one pass. According to Sonobond, the result is ultra-reliable and soft-to-the-touch seams achieved up to four times faster than with conventional sewing machines and 10 times faster than with other adhesive methods, enabling manufacturers to boost their production output. The machines offer a wide range of applications as 500 different types of pattern rollers or anvil wheels can be used with the machines.
Sonobond introduced its first SeamMaster Ultrasonic Sewing machines in October 1991 to meet demands for safer medical garments and disposable items. The machine’s high-frequency vibratory waves produce bonded edges and secure seams without stitch holes, glue gaps, fraying or unravelling to meet tough OSHA regulatory requirements for barrier seams. Applications for SeamMaster Ultrasonic Sewing machines have expanded over the past two decades and include assembly solutions whenever sewn seams are not adequate to satisfy end-use requirements.
