Claim:
1. Manufacturing process for the production of flexible three-dimensional items, made from an outer material formed by flat cuts of flexible material comprising: cutting pieces of flexible material, which form the outer material; preparing a mold and a countermold, between which a volume corresponding to that of the three-dimensional item is delimited; placing the cut pieces, which form the outer material, between the mold and countermold delimiting channels and spaces between them; injecting a plastic material through the channels and spaces; and opening the mold once the plastic material injected has solidified and then removing the item produced, wherein: the cut pieces, which form the outer material, are secured on a flexible laminated template, in a position where the cut pieces match with the outer material of the flexible three-dimensional item produced; the mold and countermold have opposing surfaces without ridges in areas occupied by the cut pieces which form the outer material of the item produced; the laminated template together with the cut pieces which form the outer material, are arranged on an inner surface of the mold, with said cut pieces facing the countermold; and a network of channels, through which the plastic material is injected, is delimited between the laminated template and the countermold, coinciding with the channels and spaces, which separate the cut pieces which form the outer material.
