Abstract
A controllable variable deflection roll of the type applying the deflection controlling force between the fixed shaft and the rotative shell via piston and cylinder arrangements, has the arrangements positioned offset circumferentially around the shaft with respect to the direction in which the deflection controlling force is applied.
Claims11
A hydraulically controlled variable deflection roller adapted to be supported for rotation opposite a counter roll so as to apply a line of pressure at the nip formed between said deflection roll and said counter roll, comprising a rotative shell having an external rolling surface and a hollow cylindrical inside, a fixed shaft extending through said inside with a radial clearance space extending around the shaft;
- a pressure element for applying a force to the inside of said rotative shell at least in the area of said nip;
- and means operated by a fluid medium under pressure for applying a force to said pressure element, said means for applying disposed at the side of said fixed shaft at an angular position which is approximately 90.degree. from the position of said nip, said means disposed so as to act between said pressure element and said fixed shaft.
