Abstract
A method of manufacturing a member such as a reinforcing member for use in a tire includes steps of arranging wires in a predetermined spaced relationship one to the others by means of a guide plate, extending the wires about rolls of a winding type brake unit, and aligning the wires by passing them through a comb roll. The method further includes steps of engaging the wires between a pair of gears arranged immediately downstream of the comb roll and driven at equal speeds to be set in wave-shapes, arranging the wires in a belt-shape in an appropriate width as a whole by means of a concaved roll, extending the wires about flat rolls to cause the wave-shapes of the wires to fall down onto a plane, and then coating the wires with a rubber. The member of the tire thus produced is uniform in quality and has a large elongation and improved anti-cutting property.
