Abstract

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.

Claims

1. A taking-up liner for taking-up an unvulcanized rubber member in a laminated fashion, said liner comprising;

a laminate consisting of a strip-like soft foamed member, a reinforcing cloth in a central portion of said soft foamed member, said reinforcing cloth having high rigidity and essentially no stretchability, and at least one elastomer layer bonded to at least one surface of said foamed member, at least one surface of said laminate being smooth.

2. The taking-up liner according to claim 1, wherein said elastomer includes a stretchable cloth.

3. The taking-up liner according to claim 1, wherein a stretchable cloth is bonded to the other surface of the laminate.

4. The taking-up liner according to claim 1, wherein said elastomer layer is a stretchable cloth.

5. The taking-up liner according to claim 1, further comprising stretchable cloths bonded to opposite surfaces of said foamed member, said at least one elastomer layer bonded to one of said stretchable cloths and a second elastomer layer bonded to the other of said stretchable cloths.

7. The taking-up liner according to claim 1, wherein said reinforcing cloth comprises polyester monofilaments as wefts ad warps.

6. The taking-up liner according to claim 6, wherein said stretchable cloths comprise a polyester knit and said elastomer layers comprise coatings of silicon rubber.
