Zusammenfassung:	Gasket is formed on portion of sheet using mould structure comprising at least two cooperating mould sections having facing surfaces defining a sheet-receiving chamber. Seals positioned in at least one of the facing surfaces resiliently support the sheet and cooperate with it to define the gasket forming cavity. At least a portion of the facing surfaces of the mould sections outside the gasket forming cavity contact each other and pref. at least one of the mould sections cooperates with the seals to define part of the gasket forming cavity. An inlet is provided for introducing flowable gasket forming material into the cavity.
