The R&S web drafter is a machine, that is constructed to influence the web structure ratio between machine direction (MD) and cross direction (CD). The modification of the fibre orientation in the web is important in order to generate equilibrium between CD and MD tensile strength and elongation. To increase the production for low weight products it is a must! You will see, your production of the card will be at least 3 times higher. If you change over to heavy products, you can lift up the top frame including rollers 600 mm, optionally 800 or 1.000 mm and you run through without draft.
