Method for winding cross-wound bobbins
The diameter of the bobbin (10) is normally calculated (20) from the speed and diameter of the friction drive drum (13) but during pattern breaking the drum speed is altered momentarily so that slip occurs. To obtain the actual momentary bobbin diameter, the speed value prior to pattern breaking is...

| Zusammenfassung: | The diameter of the bobbin (10) is normally calculated (20) from the speed and diameter of the friction drive drum (13) but during pattern breaking the drum speed is altered momentarily so that slip occurs. To obtain the actual momentary bobbin diameter, the speed value prior to pattern breaking is used to calculate the expected increase in diameter during this period, which is then added on. |
