Patent ID: 8146397

Claim:
A roll support assembly of a fibrous-web machine, comprising: a first frame part; a roll having an end which is supported on the first frame part; a second frame part which is fastened to the first frame part by an elastic fastening extending in a first direction which extends from the first frame part to the second frame part; a motion direction control mechanism which controls the motion allowed by the elastic fastening, said mechanism allowing the elastic motion of the first frame part mainly in the first direction and not substantially in other directions; wherein the elastic fastening comprises an elastic element positioned between portions of the first frame part and the second frame part; a fastener which extends through the first frame part, and the second frame part in a first direction to elastically fasten the first frame part to the second frame part; wherein the motion direction control mechanism is a first support part which is a thin metal sheet, the first support part being fastened between the first frame part and the second frame part, and extending in a second direction between the first frame part and the second frame part, the second direction being different than the first direction, the first support part extending across a deformation zone defining a width between the first frame part and the second frame part, in which the first support part is free to deflect in use in the first direction, while the first support part restricts motion in the second direction; and wherein the support part has a thickness in the first direction which is at most 15 percent of the width of the deformation zone in the second direction.
