Rolling, straightening and cutting lines

Teurema presents a compact line for cold rolling, straightening and cutting of smooth or ribbed wires, said to operate at three times the speed of a traditional line and offering the possibility of being combined with a spooler to produce coils. Teurema believes that a relatively small investment in the new LG-EC line can obtain higher productivity by a combination of reduction in manual interventions, less labour and with less space occupied by the line itself. The wire rod, from the coil positioned on the tilting fingers, will run through the vertical static payoff, the mechanical descaler, the lubricant adding unit and the Eurolls rolling cassettes until it reaches the capstan for the cold rolling deformation. The motorised rolls, besides supplying the wire back pull on the capstan, push the wire through the straightening rotor. An encoder is used for detecting the cutting length and activating the rotating shear. The cut bars are collected in a rotating channel and discharged on a bar collection bench.
