Straightener Feeder
Sheet Straightening and Feeding Unit
A unit that flattens sheet from the uncoiler with straightening rolls and feeds it with pinch rolls, in sync, to the next unit of the line (press, guillotine, roll former); built in different widths and thicknesses to suit the line.
Roll-Type Sheet Straightening and Synchronised Feeding
The straightener feeder flattens sheet from the coil and passes it to the next unit of the line in a controlled way. Width, thickness, motor power and cutting equipment are chosen to suit the line.
Straightening and Pinch Rolls
Waviness in the sheet caused by uncoiling is removed by the straightening rolls, and the sheet is driven into the line by the pinch rolls. The standard arrangement is 5 straightening + 4 pinch rolls with a roll diameter of Ø70 mm.
The unit processes sheet 0.3 – 6.0 mm thick; working width is 50 mm to 1250 mm depending on the model. Entry and exit guides align the sheet accurately to the rolls.
Speed- and Position-Controlled Feeding, Loop Synchronisation
A speed- and position-controlled AC motor of 1.1 – 4 kW feeds the sheet at an adjustable speed of 0 – 45 m/min.
The unit runs in sync with the machines before and after it via loop sensors; in press and guillotine applications that need stop-and-go, it advances the sheet by the set length in each cycle. Speed, length and production parameters are managed from the PLC + HMI touch screen.
Optional Guillotine Cut-to-Length or Direct Press Feeding
The unit can optionally be fitted with a hydraulic or eccentric guillotine shear; the shear cuts sheet up to 2 mm at up to 50 cuts per minute, to the length entered on the screen.
On press lines, the sheet is fed directly to the press's punching, cutting and bending stations without a guillotine.
