Ultrasonic Sewing Machine

Ultrasonic sewing machine that seals, sews, and trims nonwoven and synthetic fabrics in one quick, reliable step.

The SeamMaster High Profile Bonder provides good clearance for bulky fabrics or hand-guided operations.

Special fixture for welding pleated filters.

General Description

The Sonobond SeamMaster provides rapid sealing, sewing, and trimming of synthetic fabrics without thread, glue, or other consumables. Although similar in appearance and operation to traditional sewing machines, the SeamMaster High Profile bonder has a higher clearance between the wheel and the horn, making it ideal for hand-guided applications with tight tolerances, or when working around curves. Ultrasonic bonding with the SeamMaster eliminates needle and thread breakage, thread color changeover and thread unraveling problems. And with production speeds up to 4 times faster than sewing, heat sealing and adhesive machines, the SeamMaster is highly cost-effective. Sonobond’s SeamMaster is designed for specialized applications in the textile, apparel and engineered fabrics industries. A variety of interchangeable pattern rollers are available for slitting, embossing, and “stitching,” as well as custom pattern wheels designed by Sonobond engineers. The SeamMaster performs in one quick pass saving time, labor, and material. Seams bonded by Sonobond’s Seam- Master are so perfectly fused and sealed that they can be used to help comply with OSHA’s regulations for barrier seams.

Theory of Operation

Ultrasonic bonding is accomplished by channeling high-frequency vibrations to the fabric. As synthetic or nonwoven material passes between an ultrasonic unit’s horn and anvil, the vibrations are directed into the fabric where they create a rapid heat buildup. This heat causes the material’s synthetic fibers to melt and fuse, creating bonded seams that will not fray or unravel.
