ABSTRACT:
An electrode set for use in a recording apparatus and comprising a row of substantially wire-shaped electrode pins projecting freely coplanar and parallel to each other from a common carrier and being provided with integral connecting terminals for the supply of selective actuation signals, is manufactured by etching a number of plate-shaped blanks of the electrode material, so that each of them produces a number of electrode pins, the spacings between which are at least equal to the thickness of the blank after which the blanks are bent in different direction along bending lines at right angles to the electrode pins and are coupled together under mutual parallel displacement by means of a special tool, so that each spacing between adjacent electrode pins in one blank will accommodate in the same plane one electrode pin from each of the remaining blanks, the resulting spacing between the electrode pins being essentially smaller than the thickness of the electrode pins.
