EPC, which is the abbreviation of edge position control
. The automatic EPC photoelectric web guiding system is composed of a correction control board, correction controller, controller, actuator, etc. The edge or line part is tested by the photoelectric switch to pick up the deviation data signal and then wirelessly transmit the data to the photoelectric control board for logical operation, and send the manipulation data signal to the mechanical electric actuator. The electric actuator also known as electric drivers, drives the adjustment of the deviation during the operation of the coil material to ensure the uniform linear motion. The EPC controller can be used for the waterproof coiled material guiding system. It provides edge alignment to avoid the deviation of the waterproof coiled material in the whole process of production and processing and ensure the accurate and stable performance of the waterproof coiled material in the entire production process with the neat division of the rewinding machine.
