The specific workflow is as follows:

Power drive: The blade shaft is driven to rotate at high speed by a motor (such as a stepper motor).

Shearing action: The blade forms a shearing pair with a fixed bottom blade (or another rotating blade) to continuously cut off the waste edges of the fabric.

Tearing and squeezing: During shearing, the rotational motion of the blade produces a tearing and squeezing effect on the waste edges, ensuring their complete separation from the main fabric.
