Over a shift that adds up to hundreds of sheets you didn't make. A flying shear takes the stop out of the cycle — it travels with the strip, cuts on the move, and comes back while the next length is being fed. Ours cuts to 1600mm wide at up to 60 m/min. The carriage rides a linear guide, driven by a servo through a rack, synchronized to the strip by an encoder on the measuring roll. When the programmed length arrives, the blades close while the carriage is running at strip speed. No relative motion at the cut, so the edge is clean and the strip stays unmarked. Length accuracy runs about ±0.5mm on steady cuts. The first cut after a speed change is the one that drifts, because the control has to re-learn the deceleration profile. A scrap cut at the start of each order takes care of it, and it's ch…
