ABSTRACT:
In a wiper assembly (10) for a windshield, a window, a headlight, or the like, including a flexor (20) for a resilient wiping element (21) having laterally extending tabs (45,46) and lateral indents (55,56) defined on the flexor by the lateral edges (33,34) thereof. A plurality of such flexors are cut from a sheet of material without substantial waste by orienting the flexors to be cut in abutting side-by-side relationship such that the tabs of one flexor are cut from laterally aligned indents of an adjacent flexor on the sheet. The pair of tabs (45,46) have axially spaced external shoulders (49,52) located near one end (30) of the flexor with one shoulder on each lateral side of the flexor and the pair of indents (55,56) have axially spaced internal shoulders (59,62) located near the other end (31) one on each lateral side of the flexor such that adjacent flexors are oriented 180.degree. relative to each other when they are to be cut apart from the sheet.
