Abstract
Machine for separating and longitudinally slitting thin sheet, especially double-rolled aluminum sheet or foil, and for winding it onto two winding shafts in abutting strip coils, each winding station including a displaceable cylinder-biased winding carriage with a deflecting roll and a pressure roll defining a terminal sheet run unaffected by the carriage position. Slitting knives arranged on a rotatable swivel shaft in the winding carriage reach into the sheet path in its terminal run, just ahead of the winding point, the slitting knives being retractable into a safe position through rotation of the swivel shaft.
