Pot spindle for wrapping core yarns has reduced diameter spindle shaft that is out of contact with bobbin holder below center of gravity

摘要

The yarn to be wrapped is taken through a hollow spindle shaft while the wrapping yarn is supplied on a flanged bobbin carried on a bobbin holder inside a pot. The spindle shaft is not in contact with the bobbin holder in the region between the spindle bearing and the center of gravity of the bobbin. The bobbin holder is a press fit above the center of gravity.
