METHOD AND SYSTEM FOR PRODUCING ANNULAR COAXIAL STRANDED BEAD CORD

摘要

A system for producing an annular coaxial stranded bead cord in which speedy winding operation, good winding performance and good shaping performance causing no disturbance in the arrangement of a siding wire (2) are ensured. A reel (21) is made to reciprocate on the core surface of an annular core (1) transversely at a predetermined position and the annular core (1) is made to perform pendulum motion about a fulcrum, i.e. a clamp unit (13) becoming the winding point of the siding wire (2). Since a substantially constant distance is kept from the reel (21) to the winding point of the siding wire (2), the siding wire (2) being fed out from the reel (21) does not slack at the time of winding and is wound around the annular core (1) with a constant tension. In a system for winding the siding wire around the annular core by moving the reel in a box type with respect to the annular core, the siding wire is prevented from slacking by turning the reel reversely when the reel approaches the annular core.
