Zusammenfassung: | In the manufacture of a rolling lobe diaphragm by forming a sock on a spool having opposed, relatively rotatable hyperboloid portions the diaphragm is provided with a radially inextensible bead reinforcement by winding a filamentary material, such as wire, around the sock on the spool. The wire may be sheathed in uncured rubber which will bond to the sock, or a filamentary material may be used which will harden after being wound round the sock. |
