P = Load distributed on roller (dan) + own weight (dan); l = Roller length; f = Deflection (mm). Ø A mm / L J x mm Elasticity modulus DaN mm 2 Deflection mm EXAMPLE You want to know the deflection on a 1.5 meter long roller (diameter 75) carrying ribbon material whose tension is 200 dan set at a winding angle of 120 on the roller (Fig. 2.3). Load Ptot on the roller; sum of the weight of the roller and the load of the ribbon material. This will be α = 60 and therefore = 1 Fig. 2.3 P = 200 x 1 = 200 dan Weight = 1,5 x 2,687 = 4,03 Kg = 4,03 dan Ptot = ,03 = 204,03 Given the load Ptot acting on the roller, you can estimate deflection. Deflection = 204,03 x (1,5) 3 2,75 mm

9 2.3 Load as function of deflection Load in dan for 0,1% deflections of the length between supports EXAMPLE L = 1500 Deflection = 1,5 mm Load (dan) 10'000 1'000 Ø 250 Ø 200 Ø 160 Ø 140 Ø 160 Ø 60 Ø 75 Ø 85 Ø 100 Ø 100/5 Ø 120 Ø 140 Ø 160 Ø 160 L Ø 200 Ø Ø 120 Ø 100/5 Ø 100 Ø 85 Ø Ø 60 Length (mm) Fig. 2.4 Deflection is proportional to the applied load. For example, if there is a double deflection compared to that shown in the table, you will get a double load and so on. EXAMPLE You want to know the load generating a max. deflection of 4 mm on a 1.5 meter Ø 100 roller, cut across diameter 100 curve with the 1500 mm axis, you will get a value just under 300 dan. At this load, you will get a deflection of 0.1% of the overall length. The requirement was having a deflection of 4 mm, therefore the load will be P = 300 1, dan. Calculating any deflection for the final load, you will get 4.06mm. Note: the graph is in a base-10 logarithmic scale and considers the weight of the roller.
