Abstract

1,035,360. Forming and embossing elastomeric sheets. NORTH BRITISH RUBBER CO. Ltd. Oct. 8, 1964 [Nov. 25, 1963], No. 46491/63. Heading B6J. [Also in Division B5] An elastomeric sheet or blank 4, of e.g. rubber, is embossed on both sides, and contoured if required, by sandwiching the blank between a patterned rigid apertured former 2 and a similar but flexible former 5, covering the whole with a flexible blanket 6, applying a vacuum by means of manifold 1 to clamp the formers against the blank and finally steam curing the clamped blank. The blanket 6 may be of a low modulus material, e.g. gum, and may be sealed to the former 2 by a vacuum channel extending round the periphery of the former.
