ICI Mace Snag Tester

Working Principle

 The cylindrical specimen is placed on the revolving drum, and  a chained  hammer is  placed on the surface of the specimen. When the drum rotates at a constant speed, the nail hammer makes random flip and bounces on the sample surface to hook the sample. The sample surface produces snagging. After the specified number of revolutions, compare with the comparison snag Lattuca for snag rating..
