Plant for the continuous vulcanisation of mixtures of natural or synthetic latex comprising: - a plurality of vulcanisation moulds that are aligned close to each other, each comprising a base and a lid that can be removably coupled to each other by junction means and configured so as to define in said mould an annular profile that receives the mixture to be vulcanised; - a vulcanising oven of the mixture confined inside said moulds; - an input station positioned upstream of said vulcanising oven and an output station positioned downstream of said vulcanising oven; - guiding means that develop along said vulcanising oven from said input station to said output station and that identify the longitudinal direction of advance of said bases and of said moulds from said input station to said output station; - advancing means for advancing said bases and said moulds along said guiding means from said input station to said output station; - spraying means for spraying said mixture into said bases when said bases are present in said input station and are positioned along said guiding means, mutually aligned close to each other, characterised in that it comprises: - an assembly set for assembling said moulds that belongs to said input station and is configured to connect each lid to a corresponding base; - a disassembly set for disassembling said moulds that belongs to said output station and is configured to separate each lid from the corresponding base; - first transport means configured to transfer each of said bases from said disassembly set to said assembly set; - second transport means configured to transfer each of said lids from said disassembly set to said assembly set, said vulcanising oven comprising a tunnel having at least one radiofrequency set for vulcanising said mixture. - a plurality of vulcanisation moulds that are aligned close to each other, each comprising a base and a lid that can be removably coupled to each other by junction means and configured so as to define in said mould an annular profile that receives the mixture to be vulcanised; - a vulcanising oven of the mixture confined inside said moulds; - an input station positioned upstream of said vulcanising oven and an output station positioned downstream of said vulcanising oven; - guiding means that develop along said vulcanising oven from said input station to said output station and that identify the longitudinal direction of advance of said bases and of said moulds from said input station to said output station; - advancing means for advancing said bases and said moulds along said guiding means from said input station to said output station; - spraying means for spraying said mixture into said bases when said bases are present in said input station and are positioned along said guiding means, mutually aligned close to each other, - an assembly set for assembling said moulds that belongs to said input station and is configured to connect each lid to a corresponding base; - a disassembly set for disassembling said moulds that belongs to said output station and is configured to separate each lid from the corresponding base; - first transport means configured to transfer each of said bases from said disassembly set to said assembly set; - second transport means configured to transfer each of said lids from said disassembly set to said assembly set,
