Abstract

260,084. Sloper, T. Sept. 21, 1925. Moulding indiarubber. - Lengths of plastic material having a textile &c. wrapping, particularly for use as cores for tyre beads, are produced by extruding or otherwise forming a hollow length C<1> of the material, wrapping with canvas D, and then shaping (as by rollers) to the required cross-section C<3>. To avoid puckering &c. of the wrapping during the shaping operation, the external perimeter and area of the blank C<1> in crosssection corresponds with those of the shaped core C'. For convenience in wrapping, the blank C<1> is preferably of circular section.
