Abstract
Abstract A method of manufacturing laminated buses begins with a step of preparing a number of perforated sheets, each comprising a number of parallel conductor elements each of which has terminals formed at desired intervals along its length, ribs connecting the conductor elements to one another widthwise, and an outer frame connected to the connecting ribs and surrounding and integrally holding all of the conductor elements. Next, one of the perforated sheets is held at its outer frame by a jig, and an insulating material is temporarily bonded to the individual conductor elements as well as to the outer frame. The procedure is repeated until another perforated sheet and another insulating material are alternately laminated over the aforesaid insulating material. In or before the final step of finishing, all of the connecting ribs are trimmed off from the conductor elements and the resulting laminates are pressed to a desired shape.
