Abstract
The present invention concerns a new mould comprising an upper (10) in which the mould cavity (13) presents a peripheral groove (15) in at least some segments of its lateral side. A first layer (S1) made of rubber, which is preformed and provided with a leaning edge, is introduced in the mould cavity, said edge being set in said groove. A second layer (S2) made of polyurethane, is injected between the mould upper, the mould semi-rings (16) and a false mould until it reaches the upper edge of the mould. A third layer is then injected according to the standard method, so as to integrate the inferior portion of the upper. The present method allows manufacturing shoes in three colours.
