A method for moulding a closed profile member such as a sealing gasket, sequentially comprising a static step of moulding a series of contiguous sections of an unprocessed strip (40) with two open ends. Each section is moved substantially over its own length so that it is replaced by the following section once it has been moulded, and the final section is made by juxtaposing, connecting and moulding the two ends of the unprocessed strip together. A mould with two mould tools (14, 24) operative along part of its length is used to carry out the method. A temperature gradient is generated so that the temperature at the mould ends is 25-35 DEG C lower than the temperature at the centre. The mould is part of a fixed or portable device including mould heating means and means for exerting pressure on the unprocessed strip (40). |
