Abstract

U-shaped forms (1a) are cut in a band (1) consisting of electrically conductive material, which free cut the future measuring elements (1c) except for a connection at one side with band (1). The band (1) is placed on an insulating base (2) and connected with it. The band (1) is then cut along lines A and B, to provide individual electrically conductive elements (3a) arranged in succession and isolated from the teeth (3b) of the cut band (3). The thus produced scale can be reinforced by application of a carrier band (5).
