TOPIC: Variation in weight in the spool with respect to i

Variation in weight in the spool with respect to i 2 months 1 day ago #3079

Hello Everyone,

We are having weight variation in the take up bobbins. For example, Lets say The sample weight of Take up A is 7.78 gm/m. and for take up B is 7.79 gm/m. After filling 100 km in the bobbins, the net weight of Take up A should be near about 778 kgs and take up 2 should have 779 kgs. But we are having a net weight of 790 kgs (12 kgs more) in take up A and 792 kgs (13 kgs more) in the take up B.

How is this extra weight coming in the bobbins?? We have kept the standard dancer pressure, used almost similar dies. Then what is playing in it to increase the net weight of the bobbin??

Note: Some of the machines are giving almost equal net weight with respect to the sample weight.
