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)

Low alloy steel and low carbon
Coil-loading——single head uncoiling——Coil-end-feeding & shoveling——2 pinch rolls & 5-rollers
leveling——head cutting----Hole Accumulator(1)-----aligning----Disc slitting——Scrap rewinder
——Hole Accumulator(2)——Pre-separator/Tensioner——Separator & Recoiler——Coils-discharging
——Hydraulic control——Electric control
The reverse loop accumulator is installed between the shear& welder and the forming line, Its purpose is to give enough time for feeding the new coil from uncoiler to shear & welder to cut and join end of the new coil with tail end of previous coil.
