Abstract
A tire reinforcement structure having parallel threads is made by providing a substantially toroidal rotatable form and a reinforcement-constructing an apparatus disposed adjacent the form. At a forming section of the apparatus a group of multiple parallel threads is formed. The group of threads is fed to a joining section where the threads are embedded in an elastomeric composition to form a strip which is fed to a cutting section where the strip is successively cut into portions. The strip portions are successively fed to a depositing section which successively deposits the portions of the strip along a predetermined trajectory onto the surface of the rotating form. The strip portions are formed in situ at the form and are deposited directly onto the form from the depositing section.
