Summary:

Shoelace abrasion test machine is mainly used to measure the frictional property of shoelaces that

repeated abrade the the eyelet, or measure the frictional property of standard eyelet that repeated abraded by shoelaces. This machine is suitable for all types of shoelaces and eyelet.A section of the shoelace through the eyelet that being clamped by a fiberboard (cardboard). Eyelet and shoelace turn into 90 °, fiberboard and shoelace turn into 45 °, and then tensing the shoelaces under the standard power and pull the eyelet back and forth until the shoelaces damaged, and then stop testing.

Principle:

Take two shoelace, mutually hook in the middle. Clamp the both ends of the shoelace at the movable fixture of shoelace rubbing tester, which can make reciprocating linear motion; clamp one end of the other shoelace on the corresponding fied fixture and another end of the shoelace round by a fixed pulley and hanging the a weight. Make the two shoelace abrasion each other by reciprocating linear motion. Then check the wear resistance, when the machine run up to pre-set times, the machine stop.
