Slitting Line
Features:
l Low operating costs
l High automation level to reduce non-productive times
l Flexibility from customer-specific arrangement and design
l Fully automatic strip threading systems
l Fully automatic coil peeler for over-payoff and under-payoff uncoilers
l Double slitters(optional), one slitter in production, the other in tool setting, interchanged
after the production is finished, minimize the time for tool changing
l Fully automatic adjustment of edge scrap guiding, automatic scraps discharge
l Automatic clamping and unclamping of the cutting tools on the knife arbor
l Automatic strip strand transfer systems
l Special braking units for strips with high surface finish(optional)
l ESCL series slitter and CTL combined lines combine a slitter and a shear into one line. They not
only can do slitting and recoiling but also cut-to-length and stacking of coil material.
