The Weldsonic™ Blind is designed to apply edge tapes or seal edges of different fabrics mainly for the internal sun protection for the automotive industry.
As a heat generator we use a rotating ultrasonic sonotrode in relation with the appropriate anvil. Depending on the processing type you can use the direct welding or an additive, like a hotmelt tape. A sealed edge-cut or edging is as well possible. To work with constant quality and simplest handling, the fabric is clamped with its whole length on a movable sleight. The movable sleight contains a material supporting surface of 1000 mm x 500 mm (other sizes on request) and is electrically synchronized with the welding process. Due to the use of a servomotor, really fast reverse speed is possible. Through the clamps along the processing edge, an absolute straight seam trend is reached without guiding device and manual influences. Material beginning and end edge are recognized by a light barrier, which starts and ends welding processes and separates the tape automatically.
