A flanged plate () for a rolling-lobe air spring has on its rounded portion an annular, closed, concave, rounded holding recess () which has a circular arcuate shape. The plate is provided with the recess before surface treatment. A correspondingly shaped holding bead () in the upper flanging tool () engages in this holding recess and form-tightly holds the tool () and the flanged plate (). In this way, sharp-edged holding grooves, which can damage the surface of the flanged plate, are unnecessary. The flanging method, the flanging device, the flanged plate and the rolling-lobe air spring provided with a flanged plate of the above type are described.

The invention relates to a feeding device for strip-shaped tire components. The inventive device is situated in a conveying device for a tire construction drum. The feeding device comprises one or several storage means, feeding and cutting devices pertaining thereto as well as transport devices by means of which the cut tire components are transported to the tire construction drum. The transport devices which withdraw the tire component from the storage means and position said tire component under the cutting device and the transport devices which transport the cut tire component to the tire construction drum are configured as an interconnected one-piece transport system in a transport line. The transport system can be displaced between a rear cutting and feeding position and a support position that is moved to the front. The conveying devices are arranged in such a way that the one-piece transport system engages with the cutting devices in the rear position thereof. The conveying devices and the one-piece transport system are provided with holding and fixing devices for the tire component. The holding and fixing devices can be carried to the tire component and fix the tire component during displacement of the one-piece transport system, whereby said component has been withdrawn from the storage means and, after cutting, remains adjacent to the storage means in relation to the cutting line. Said holding and fixing devices also fix the tire component that is already fed to the one-piece transport system.
