The doffer shaft typically consists of a long, cylindrical metal shaft with attached doffer pads or blades that help to strip the cotton from the spindles. These blades or pads are strategically placed along the shaft to efficiently remove the cotton fibers as the shaft rotates.

The proper functioning of the doffer shaft is crucial for the efficient harvesting of cotton, as it ensures that the cotton is effectively stripped from the spindles and collected. Regular maintenance and inspection of the doffer shaft are important to ensure that it is in good working condition and free from any damage or wear that could affect the machine’s performance. If the doffer shaft is not working properly, it can lead to reduced harvesting efficiency and potential damage to harvested cotton fibers.
