Abstract: A rubber or rubber-like article containing a textile reinforcing member comprising a plurality of continuous filamentary elements in the form of cords, e.g. of glass, nylon or polyester material, or of fabric formed of such cords arranged in parallel longitudinal relation and held together by spaced lateral warp threads, is produced by a process in which prior to incorporating the member into the article it is progressively flexed along its length under tension so that the flexibility of the member is greater after flexing then before flexing. Prior to flexing the member may have been dipped in an adhesive which bonds it to rubber, dried and hot stretched. After flexing the member may be embedded in uncured rubber applied by calendering, formed into a laminated article, e.g. a tire, and vulcanized. The flexing apparatus shown in Fig. 2 comprises two parallel frame members 10 that support idler rolls 11 and 12 mounted in bearings 14 secured to the bottom of frame members 10 and adapted to guide web 13.
