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.

Abstract: A winding machine with a rewind shaft supported between power-operated roll supporting arms, with a pressure roller cooperating with the rewind shaft, and with a supporting drum for the rewind shaft and/or the roll, respectively. The technical problem of the invention is a simple supporting of the rewind shaft and/or the roll which does not impede the pivoting of the rewind shaft for the change of the roll as well as the pulling out of the rewind shaft from the roll pivoted down. By the superposition of the pivoting motions of roll supporting arms and pivoting levers the supporting drum supports the roll substantially from below for any roll diameter. By the continuation of the pivoting motions of the roll supporting arms as well as of the supporting drum beyond the winding range, supporting drum and roll move away from one another so far that the roll can be placed on a pallet or on a carriage, without the supporting drum being impeding.
