Abstract
Abstract The apparatus disclosed comprises a self-propelled carriage fitted with ultrasonic slitting, welding and/or embossing means and is adapted for translating motion along a set of guide rails. The ultrasonic means include a power supply and a converter unit with resonating horn opposed by a movable anvil means, the translating motion of the carriage being correlated with the motion of the anvil means. The apparatus is adapted to ultrasonically slit, weld or emboss wide sheet material, for instance slitting sheet material to blanket size, while simultaneously sealing the cut edges as such sheet material is taken from a loom.
