ANORDNING FOR FASTSPENNING AV EN SLUTEN MANTEL

摘要

A device for fastening a closed casing, such as a wire cloth, which should form the circumferential surface of a cylinder, such as a screening drum, has a supporting member with a circularly cylindrical outer surface which is intended to be inserted in the casing at one end thereof and has substantially the same circumference as the casing. The supporting member has a circumferential groove in its outer surface. A circumferential engagement element which is made of an elastic material is so mounted in the groove that its outer surface is located on substantially the same level as the outer surface of the supporting member. A mounting ring is disposed around the engagement element. A pressure applying mechanism is adapted to clamp the casing between the engagement element and the mounting ring by deforming the engagement element in such a manner that at least the portion of the outer surface of the engagement element which is inserted farthest in the casing is raised to a level above the outer surface of the supporting member.
