This tester is developed as a pre-processing device for collecting samples for CMT testing. It works in the following mechanism. On a corrugating machine, pre-heated corrugating medium is threaded through corrugating rolls (gear-shaped) heated to 177±5ºC under a certain pressure, during which process corrugation is performed. The specimen formed is fixed in a rack using a ten-pin cantilever apparatus and then attached to the rack with adhesive tape to form one-sided corrugated board.
