The process of machine spinning usually includes the following steps, which can be achieved by different machine combinations:

1. Raw material preparation (opening and cleaning)
The raw materials are generally natural fibers (such as cotton, wool) or synthetic fibers (such as polyester). These fibers first need to go through the "opening and cleaning" step, the purpose of which is to remove impurities, seeds and short fibers from the raw materials, and loosen the fibers to make them more suitable for subsequent spinning operations. Common equipment is a cotton opener.

2. Carding (combing)
The process of carding is to further straighten the fibers after opening and cleaning. By combing, the fibers will be arranged neatly and the fibers of different lengths will be separated. This process usually uses a cotton carding machine, which combs the fibers into uniform fiber bundles (called "fiber strips" or "comb strips").

3. Drawing
The combed fiber strips are sometimes combined together through the "drawing" process to improve the uniformity and strength of the fiber strips. This process usually uses a drawing machine. The result after drawing is a more uniform "drawing strip".

4. Spun (Roving)
Next, the roving frame further stretches and twists the drawn fibers to form a thicker yarn. This is the first step in the spinning process, and the resulting yarn is uneven in thickness and belongs to the roving state.

5. Worsted (Fine Yarn)
After the roving process, the yarn becomes finer and more uniform. The spinning frame increases the strength, smoothness and uniformity of the yarn to the final yarn standard through multiple stretching and twisting.

6. Winding (Rolling)
Finally, the spun yarn will pass through the winding machine, which will wind the yarn into a bobbin or yarn cone for storage, transportation or further processing. This step ensures that the yarn will not be tangled or scattered.

7. Finishing (Finishing)
Sometimes, the yarn will be finished, such as dyeing, shaping, etc., to improve the functionality, appearance and suitability of the yarn.

Through these steps, the raw fiber can finally be transformed into yarn, ready for further use in the production of weaving or other textiles.

Different textile mills adjust and configure their machines according to the type of yarn they produce (such as coarse yarn, fine yarn, single yarn, multi-ply yarn, etc.).
