In a method of moulding a sole of a plastic material and a welt on a shoe upper ( 1 ) a mould ( 3 ) is used. The mould ( 3 ) includes at last ( 2 ), upon which a shoe upper ( 1 ) is arranged, an upper mould part ( 5 ) divided along a longitudinal middle plane and thus includes two halves ( 5 a , 5 b) being laterally movable in relation to the lower mould part ( 4 ) between an open and a closed mould position, and a lower mould part ( 4 ) being vertically movable in relation to the upper mould part ( 5 ) between an open and a closed mould position. For carrying out the method an annular shoe welt ( 6 ) is provided and arranged in the mould in the mould's open position. The two halves ( 5 a , 5 b) of the upper mould part ( 5 ) are closed and the lower mould part is moved into its closed position. As a result a circumferential support surface ( 7 ) on the upper face of the lower mould part ( 4 ) co-acts with a pressure surface ( 17 ) on the lower face of a projection ( 15 ) on each half ( 5 a , 5 b) of the upper mould part such that the portion of the welt ( 6 ) facing the shoe upper ( 1 ) it tilted inwards and downwards to bring the inner end face of the welt ( 6 ) into sealing engagement with the lower side section of the shoe upper ( 1 ). The shoe sole is then moulded in a manner known per se by supplying a plastic material to the cavity of the mould. |
