Abstract
The invention relates to an ultrasonic welding and cutting device for use in the manufacture of a flat-cable. The flat cable includes a plurality of wire conductors which are arranged in parallel at a given interval with respect to each other and interposed between first and second insulator films. The device has a product flow line in an upstream to downstream direction. The device comprises a horn unit including a horn melter unit that imparts ultrasonic oscillations, and a horn cutter unit. The horn melter unit and the horn cutter unit are located sequentially from upstream to downstream at a predetermined distance along the product flow line. The device further includes an anvil unit including an anvil melter unit and at least one anvil blade unit. The anvil melter unit and the at least one anvil blade unit respectively face the horn melter unit and the horn cutter unit along the product flow line, such that, when the first and second insulator films containing the plurality of wire conductors are passed between the horn and anvil units, the first and second insulator films can be fused and adhered by the horn and anvil melter units, and successively fused and cut or trimmed by…
