Embodiment Construction
[0053] image 3 The flat cable manufacturing line is schematically shown, in which the ultrasonic welding and cutting equipment of the present invention is installed. First, a plurality of conductor supply reels 32 are installed at the most upstream end of the production line P. The wire conductor 31 is stored around these reels 32. A pair of pitch guides 33a, 33b are provided downstream of the conductor supply drum 32, which guide and arrange the wire conductors 31 to be parallel to each other at a given interval.
[0054] The conductor supply reel 32 is initially wound with corresponding wire conductors made of copper or copper alloy. The number of wire conductors is the same as the number of conductor elements to be incorporated into the flat cable. In the illustrated embodiment, five wire conductors 31 are used, and they are stored around the corresponding conductor supply reel 32. Each wire conductor 31 may be, for example, a soft copper wire with a rectangular cross section...

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 to each other and interposed between first and second insulator films. The device has a product flow line with an upstream to downstream direction. The device comprises a horn means including a horn melter unit for imparting 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 comprises an anvil means including an anvil melter unit and one or several anvil blade unit(s). The anvil melter unit and the anvil blade unit(s) 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 means, 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 the horn cutter unit and anvil blade unit(s), respectively along the product flow line.
Description
Technical field [0001] The present invention relates to a flat cable manufacturing equipment, in which a plurality of wire conductors are arranged in parallel with each other at a given interval and are enclosed by a pair of insulating films. Background technique [0002] There is such a flat cable in the prior art, and it is known to have the following advantages: that is, compared with a single wire conductor, the flat cable requires less space and reduces the total weight per unit wire conductor capacity. The above-mentioned insulating film is formed of, for example, a polyester-based material, wherein an insulating material with good insulating properties, such as polyethylene terephthalate (PET), is used as the base portion, and one surface of the portion is coated with, for example, Adhesive layer made of thermoplastic material. [0003] figure 1 An example of a known method for manufacturing such a flat cable is shown. The base portions of the insu...
