Abstract:
An apparatus for fatigue testing cord, cable or filamentary material comprising:(a) a tensioner (14) which is electronically controlled and used to constantly increase the tension of a cord, cable, or filament (12) to be tested, whereby a first end of said cord, cable or filament (12) is attached to said tensioner (14) (b) a rolling mechanism (30) directly or indirectly connected to tensioner (14) by cord, cable, or filament (12) for bending said cord cable or filament (12), the rolling mechanism (30) comprising: a stationary roller (18) and a non-stationary roller (20), wherein the non-stationary roller (20) rides against said stationary roller (18) (c) a crank arm (22) connecting said non-stationary roller (20) to a rotating driving mechanism (24), whereby said crank arm (22) is attached to said driving mechanism (24) at a perimeter thereof and when said driving mechanism (24) rotates said crank arm (22) causes said non-stationary roller (20) to move back and forth.
