ABSTRACT:
For producing load cells, especially for platform scales in which a beam that is clamped at one end in a bending stiff manner, is loaded at its opposite end, the measuring spring (1) is formed by a section (2) of a blank having a constant cross-section along its length. The section (2) is severed from the blank by parallel cuts so that the cut end surfaces (4) of the measuring spring (1) extend in parallel to each other and at a slant of an angle (.alpha.) to the central plane (3). Hereby the expense for material is reduced.
