Abstract
A web-slitting machine has its blades mounted on cylinders shifted along a linear guide extending the full width of the web to be slit. The sliders carry tubes whose suction nozzles are disposed in the regions of the blades and which terminate in connecting heads having boat-shaped projections received between elastomeric sealing lips closing a slit of a suction box extending along the guide.
