Our Conventional Coil Line DSF3 are the perfect solution to feed the Press for any kind of material without Compromises
because every machine has a dedicate work to do, The Decoiler has to keep the coil closed in order to do not spring out the band, The Straightener run at constant speed (variable and programmable of course) in order to produce a perfect planarity and to supply a loop in smoth way, The Feeder will position the material into the die controlled via Servomotor, cecked by a measure whell with encoder directly on the band and be controlled into the die when possible, The Feeder will be synchro at the Press via an absolute encoder placed on the Press shaft , the DSF3 are suitable for band from 0,7 to 3 mm thickness with all material like Normal Steel, Stainless Steel, Aluminium and Copper , for really delicate material the feeder rolls can be covered by Adiprene.
