or more dryers per felt in general a greater number of dryer fabrics has the advantage of reducing the cost and the difficulty in replacing a fabric if one is damaged on the other hand fewer dryer fabrics means less square footage of fabric and lower cost generally it is preferred to have more than one cylinder per fabric however due to the cost of fabrics and the possibility of fabric damage it is also desirable to not have any one fabric with excessive length in any event upper dryers 24 and lower dryers 26 utilize separate felts in general the number of dryer fabrics is equal to the number of times 2 divides evenly into the number of cylinders plus one if the number of cylinders is odd one advantage achieved by the dryer sections 20 and 120 is that the number of dryer or felt roll drive positions required to provide adequate drivability to the dryer sections is less than that which would be required in conventional fabric driven dryer sections in the present invention only one drive cylinder per dryer section would typically be required the plane containing the axes 42 of the dryers 22 in the upper row 24 is vertically spaced from the.
