An integrally formed single piece light strip and light strip manufacturing system. The control system includes a movement detector in the form of an optical encoder to detect movement of a DC motor. The clamping sections are each provided on a support unit by means of which the clamping sections, during the forward movement of the metal element, are automatically moved apart essentially perpendicularly to the direction of movement of the metal element. The at least two double-sided wiring boards are bonded by means of a polyimide adhesive resin that is selectively applied by screen printing on the double-sided wiring boards other than on the connection terminals.
