A latex foam product may be manufactured by a method comprising applying, onto a carrier sheet, a first layer comprising a layer of a foamed vulcanisable latex composition; applying, onto the first layer, a second layer of a foamed vulcanisable latex composition and then heating the resulting layered product to effect vulcanisation of the foamed vulcanisable latex compositions in the first and second layers. The method makes it possible to manufacture a two-foam layer product, e.g. cushioning components for footwear, in which the two foam layers are strongly bonded to each other. Because the method involves only one vulcanisation operation, it offers both technical and economic advantages over prior art methods. |
