Continuous production method of flexible circuit board

The invention belongs to the technical field of flexible circuit boards, and discloses a continuous production method of a flexible circuit board. The flexible circuit board includes an insulating layer and a metal layer. A knife roll is adopted for cutting, a sliding roll is adopted for supporting or traction, and a waste discharge film dynamically wound on the sliding roll or attached to the back of the insulating layer or the metal layer is used to strip away discontinuous waste formed by cutting the insulating layer and/or the metal layer. The discontinuous waste formed by cutting is continuously stripped away through the waste discharge film, and the waste discharge film is a film which is viscous on one side. During or after cutting, the viscous side of the waste discharge film is first adhered to the cut metal layer or insulating layer and then torn off from the cut metal layer or insulating layer. When the waste discharge film leaves the metal layer or the insulating layer, thediscontinuous waste form
