Abstract: A method for producing profile sealing rings, in particular in a C-, V-, or U-shape, in which a profile strand (24) of definable cross-sectional shape is obtained from a band-shaped carrier part (2) by forming and the use of forming rolls (14, 16, 20, 22), the process of forming proceeding such that the profile strand (24) assumes at least part of an arc shape or spiral shape after forming.

Abstract: In order to produce a combination of a screw member comprising a screw head, a threaded portion and a shank portion which is arranged between the screw head and the threaded portion and has an external diameter that is smaller than the external diameter of the threaded portion, a washer incorporating a passage opening the diameter of which is smaller than the external diameter of the threaded portion, and a sleeve the internal diameter of which is greater than the external diameter of the threaded portion, whereby said combination can be produced in a simple manner but nevertheless ensures that the sleeve and the washer are held securely on the screw member, it is proposed that the sleeve have at least one projection which engages in a recess provided in the washer, wherein the sleeve is pressed against the washer in such a manner that the sleeve and the washer are connected together and held captive on the screw member.
