Abstract: A seal arrangement has two machine parts movable toward one another along or about a movement axis. One of the two machine parts forms a seal holding structure and the other forms a sealing surface. A sealing device between the two machine parts is arranged on or in the seal holding structure, wherein the sealing device includes a sealing element and a pre-tensioning element which is separate from the sealing element and by means of which the sealing element is tensioned in the radial direction against the sealing surface of the respectively other machine part. The sealing element is formed by an elastically deformable sealing film. On the sealing film side, the pre-tensioning element forms an embossed structure which presses into the sealing film where the sealing film bears against the sealing surface with a contact pressure progression which corresponds to the embossed structure of the pre-tensioning element.

Abstract: A rotary seal arrangement includes two machine parts arranged to be rotatable relative to one another about an axis of rotation. One of the two machine parts forms a seal retaining structure and the respective other of the two machine parts forms a sealing surface. A rotary seal is formed between the two machine parts with an elastically deformable retaining element of the one machine part and with a sealing element which bears in a sealing manner with a surface pressure against the sealing surface of the other machine part. The sealing element is designed as a helical spring sealing element arranged extending coaxially to the axis of rotation and arranged in a circumferential groove of the retaining element and twists proportionally to the frictional resistance between the helical spring sealing element and the sealing surface. Contact surface pressure is reduced between the helical spring sealing element and sealing surface.

Abstract: Encoded scale bodies for position/displacement measuring systems and position/displacement measurement systems including scale bodies are disclosed. An encoded scale body includes a support band and at least one encoding layer made of encoding material. The encoding layer is arranged on the support band. The encoded scale body further includes a cover band which covers the encoding material towards an outside space. The cover band is formed by the support band. The support band/cover band is elastically flexible. The support band, which is the mechanical holder for the encoding material, may serve to mechanically stabilize the encoded scale body. The cover band covers the encoding material and may protect the encoding layer from external effects such as, in particular, mechanical forces. The flexible support band/cover band may permit the encoded scale body to be used as band material, and for example, a roll material.
