A taking-up liner for taking-up an unvulcanized rubber member in a laminated fashion is disclosed, which comprises a strip-like base cloth having stretchability, and at least one elastomer layer bonded to at least one opposite surfaces of said base cloth. The elastomer layer has stretchability, elasticity, and a smooth surface. Alternatively, the taking-up liner may be constituted by a laminate consisting of a strip-like soft foamed member, and at least one elastomer layer bonded to at least one surface of the foamed member. the surface of the laminate is made smooth.

Taking-up liners for unvulcanized rubber members

A take-up liner for uncured rubber members is a band-like laminate of inextensible reinforcing cloth, flexible foamed layer arranged thereon, extensible cloth arranged thereon and sheet-like elastomer layer adhered thereto and has a helical formed shape.

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.
