We process the reel further on our doubling machine. Here, two single-layer paper webs are combined to form a new, two-layer paper web. The resulting paper rolls are called mother rolls, because smaller rolls are produced from them, which you can then buy. The mother rolls have a diameter of approx. 1.8 m, are 2.6 m wide and weigh 1700 kg. The giant rolls are now given a running card and are transported to the mother roll warehouse.
