balance rating of q u2266 1 0 the roll also typically has at operating speed a running truth of u2266 50 u03bcm in the roll 39 s longitudinal center 7 the fiber composite material of core 3 can be configured such that temperature changes will lead to a change in a length l fig2 of the roll but will not lead to a change in a diameter d of the roll alternatively core 3 can be configured such that temperature changes will lead to a change in diameter d but not to a change in length l the roll may be equipped on its ends or bearing area 8 with metal reinforcements 9 to which attach a bearing shaft 10 coupled to bearing shaft 10 is a bearing 11 and as the case may be a drive 12 the manufacture of core 3 of fiber composite material may necessitate providing in the center an additional thin substrate 16 of selected material on which the composite plastic is applied with the aid of the known filament winding process depending on the manufacturing process substrate 16 remains bonded to core 3 or is removed later as clearly shown in the drawings each of cover 1 core 3 and substrate 16 are of a monolithic unitary construction another embodiment of an applicator roll of the present invention is shown in fig3 the roll includes a substantially solid and cylindrical body 18 formed of fiber composite material body 18 is surrounded by a cover 1 substantially identical to that of fig1 while this invention has been described as having a preferred design the present invention can be further.
