The drafting arrangement


In the Rieter comber, the sliver table leads to a vertically inclined 3-over-3 drafting arrangement (Fig. 56), sometimes with an additional pressure bar in the main draft zone. The rollers form two drafting zones. Break draft as well as main draft distances and the amounts of draft are variable. The overall draft lies between 9 and 16. At the delivery end of the drafting arrangement a trumpet collects the discharged web and guides it, with additional compacting, to the delivery rollers.
