Working Principle of the Paper GSM Cutter

A sheet of raw sample is horizontally placed on the cutting platform of the cylindrical punching head. The ball at the end of the lever is held by a hand and pressed downward quickly to drive the blade to punch the test sample. A single test piece with a specified area and shape is obtained.

Operating Steps

  1. Place the instrument on a horizontal and stable workbench.
  2. Place the paper flat on the center of the punching pedestal, and hold the support at the top with your left hand to prevent the sampler from tilting forward when the lever is pressed. Then quickly press the lever to complete sampling with your right hand. The sample taken will fall into the chute.
  3. Slowly loosen the pressure lever, allowing the upper punching blade to return to the starting position.
  4. Take out the sample and carry out the corresponding test.
