This machine can test the wear resistance of shoelaces. Take the middle sections of multiple shoelaces and hook them to form one on the left and one on the right, and clamp them with this machine's fixture, which is different from the traditional shoelace wear resistance test machine. It adopts the lightweight silent test. During the test, the moving clip moves back and forth at a constant speed in a straight line, so that the middle sections of multiple shoelaces rub against each other. Record the friction times when the test reaches the specified friction times or the shoelaces are broken.
