PURPOSE: A vacuum absorption apparatus for supplying metal coil materials is provided to adjust the coverage of adhesion force according to the diameter length of coil material and prevent coil material from being deviated during a transferring process due to the weakness of the adhesion force or external shock. CONSTITUTION: A vacuum absorption apparatus for supplying metal coil materials comprises a vacuum suction unit(30), a safety support unit(20), a coil checking unit(40), and a fixing ring(502). An air inlet(305) connected to an air pathway is punched on the upper side of a circular suction base plate. A connection hose(303) with an opening/closing valve(303a) is formed on an air inlet. The vacuum suction unit comprises a vacuum suction rail(302). A support bracket(301) is installed on the both sides of the vacuum suction rail. A metal coil material(S) is supported on each end of the support bracket.
