The invention relates to a product line of daylight lamp support, which comprises a material feeder, a rolling edge folder, a secondary material feeder, a slicing punch device and a folded groove molding device. Wherein, a material storage chamber is arranged between the material feeder and the rolling edge folder; and the rolling edge folder, the secondary material feeder, the slicing punching device and the folder groove molding device are controlled by digital control tank. The invention has high automatic degree, lower fail rate, and high producing efficiency, while the whole product line is controlled by one person, to save human resource and improve the producing safety. And the rolling edge folder is prepared by multi-working position molding, while the distortion is increased when the work-piece passes through one group of conjugate rolling wheels, to form needed folded edge; and the rigid distortion of work-piece is small, the product quality is stable and it can apply batch industrial production.
