The Smith Roll Tightness Tester also called as Roll Hardness Tester determines roll winding uniformity to eliminate roll bursting and press breakdown from poorly wound rolls.
Paper Rolls not wound with uniform tension can cause a variety of problems. Large diameter rolls that are extremely tight on the outside tend to burst during handling and shipping. Uneven roll tightness often results in starring- the warping of the winding core. On high speed web presses, the warped core causes uneven feed and paper jerking and can cause the breakdown of the press.
It is often used with TMI Paper Roll Hardness Tester Model 40-20.
