The toughness value of the nylon strip is obtained by the degree difference of the dynamometer 10. Before and during drawing, the first electromagnetic slide rail 14 is used to drive the dial indicator 17 to move, so that the roller 18 presses over the surface of the nylon strip to obtain the thickness deformation of the nylon strip during the drawing process.
