Data Collection:

Ply Width- Total 24 readings of ply width was taken out of which 18 were taken on fisher cutter and remaining 6 on HTBC cutter.
Ply Angle- Total 24 readings of ply angle was taken out of which 18 were taken on fisher cutter and remaining 6 on HTBC cutter.
Ply Gauge- Total 10 readings of ply gauge was taken on fabric calender.
EPI- Total 10 readings were taken for EPI of a fabric. In this case a long length of fabric was cut in horizontal direction on take up roller and the fabric were cut into 5 equal parts. After this EPI of each part was noted down.

Conclusion:

Ply Width:

In the case of ply width tolerance limit is of 3mm. All of the above readings are in tolerance limit. Hence there is no specific error in ply width.

Ply Angle:

In the case of ply angle, we can see a slight deviation of 0.01 degree in some cases which is negligible. In rest of the cases set value and measured value matches with each other. Hence there is no error in ply angle.

Ply Gauge:

Fabrics like P361 and P385 should have a gauge of 1.2 mm. In the above readings there a deviation up to 0.05 mm which can be neglected.

EPI:

P385 fabric should have a EPI of 32. In above readings we are having reding near about equal to 32. Missing or extra reading of 2 cords can be accepted.
