The Weldsonic™Twin ultrasonic bonding system uses two 35 KHz rotary sonotrodes to join acrylic, polyester, and similar membranes with hot melt adhesive tape or to weld thermoplast coated fabrics directly. The ultrasonic mechanism moves along the work table while the material being joined is clamped. Guiding devices for various seam operations are available to ensure correct material and adhesive alignment. The guiding devices are mounted to the machine with a pneumatic “quick change” holder. The integrated control system allows material specific operating parameters to be easily set and saved using the touch screen. Frequently used programs are accessible by “single touch” recall buttons. A temperature sensor monitors seam heat during operation and can be used to ensure seam quality. Application: Continuous welding of long straight seams for hems, assemblies and reinforcement tapes on thermoplastic coated fabrics such as Screens, Soltis® etc. as well as bonding of non fuseable fabrics like acryllic and polyester awnings by means of heat activated adhesive tapes of GLUETEX. Concept: Material panels to be joined are positioned on the work table, positioned into the guiding device, and held in place with the stationary clamps at machine start position. A moveable clamp is used to hold the material at end of seam position, and provide a slight tension on the material. After pressing the “start” button, the ultrasonic mechanism moves on a precision linear guide down the work …
