Abstract

A method, and apparatus, for determining bend resistance of a sample includes applying a weight to a sample and measuring an amount of deflection of the sample caused by applying the weight. The sample is provided on a sample holder and an initial position of the sample is measured with respect to the sample holder. A weight is applied to the sample and a change in position from the initial position to a deflection position of the sample due to the weight applied to the sample is measured. An amount of deflection of the sample is determined by dividing the change in position by the basis weight.

Claims (16)

1. A method, comprising:

providing a sample on a sample holder;

measuring an initial position of the sample with respect to the sample holder;

applying a weight to the sample;

measuring a change in position from the initial position to a deflection position of the sample due to the weight applied to the sample; and

determining an amount of deflection of the sample based on the change in position and a basis weight of the sample,

wherein the amount of deflection is determined using the following formula: (weight applied to the sample×change in position of sample)/basis weight of the sample.

2. The method according to claim 1 , wherein the sample comprises paper.

3. The method according to claim 1 , wherein the sample comprises printer paper.

4. The method according to claim 1 , wherein the sample comprises a single sheet of paper.

5. The method according to claim 1 , further comprising determining the basis weight of the sample.

6. The method according to claim 1 , further comprising applying a plurality of different weights to the sample in series.

7. The method according to claim 6 , wherein said measuring the change in position from the initial position to the deflection position of the sample due to the weight applied to the sample and said determining the amount of deflection of the sample by dividing the change in position by the basis weight of the sample are each repeated for each of the plurality of weights.

8. The method according to claim 1 , wherein said measuring the change in position from the initial position to the deflection position of the sample due to the weight applied to the sample comprises positioning a gauge at a lowest point of the sample on the sample holder.

9. The method according to claim 1 , wherein said providing the sample on the sample holder comprises cutting a sample to a fixed dimension.

10. The method according to claim 1 , further comprising determining a placement of the sample on the sample holder based on a direction in which sample deflection is to be tested.
