A method of manufacturing a tire bead ring of the package type by winding metal wires on a form of revolution, the radially inner face of the tire bead ring having a frusto-conical shape of half angle alpha at the apex and of radius R with respect to the axis of rotation of the tire bead ring, in which a permanent circular deformation is effected on the wires prior to their winding on the form of...

A foamed plastic and a method for its production are described. Tne foamed plastic has cavities which consist of open cells or pores. In at least a portion of the cavities, particles of water-insoluble hydrophilic polymer are homogeneously distributed, the particles being swellable to a gel in water. Examples of such polymer particles are granules of cross-linked dextran. The polymer particles are...
