The ‘UNILAB’ Pilling Tester consists of two wooden cubic boxes with inside surfaces lined with cork and outer surfaces laminated.  These boxes are rotated about their central axis at a specified speed with the help of a motor and a gear box.  A ore-set stroke counter stops the motor automatically after the desired number of revolutions. The test specimens are firmly held around rubber tubes.  Four such tubes are placed in each box and then rotated for desired numbers of revolutions after which they are assessed visually against standard rating photographs and graded. The apparatus is finished in dark metallic green. The boxes are covered with a layer of off white laminated sheet.

Eight Rubber tubes, one insertion tool, and a template for marking on the specimen are supplied as standard accessories.
