[0002] The truss reinforcement used in precast concrete composite slabs requires a truss machine when producing the truss reinforcement. When the truss machine produces the truss reinforcement, the steel bar coils are placed on the coil pay-off rack. The coil pay-off rack rotates under the drive of the motor according to the truss production speed to provide steel bars for the truss machine. Since the truss machine has a welding step during production, the steel bar conveying needs to be stopped during welding, which requires the coil pay-off rack to be braked in time.
