A machine for slitting strips of elongated sheet material from a wider roll of the material in which two spaced mandrels are mounted vertically on a frame and the sheet of material extends from the mandrel past a carriage to the second mandrel. The carriage carries two engaging circular knives mounted on the carriage for rotation about vertical axes, the knives engaging opposite sides of the sheet to cut a strip from the upper edge of the sheet. The carriage is provided with a guide to maintain the selected distance from the upper edge of the sheet to the cutting plane of the circular knives.
