Title:
弾性マットの製造方法
Document Type and Number:
Japanese Patent JP4339935
Kind Code:
B2
Abstract:
This is a new way of manufacturing a flat rubber moulding, with projections underneath. It forms an underlayer for a ballast bed. The elastic material of the mat is vulcanised in a hot panel moulding press, with a number of moulding cavities for the projections. In the novel procedure, a fabric with open weave (15) is laid in the press, placing it onto that half of mould (13) with the moulding cavities (14). It covers the entire cavity over one stage of heating. A slab of raw rubber (17) is laid onto the fabric. During press closure, the fabric becomes impregnated by the plasticised raw rubber. Air and other gases from the mould cavity are removed, passing through the fibres of the fabric, to the edge (16) of the mould. The fabric becomes embedded into the rubber moulding.
