PROCESS FOR MAKING AN INSOLE OR FUSSBET FOR SHOES AND RESPECTIVE INSOLE OR FUSSBET

摘要

Process for making an insole and/or fussbet (10) composed of at least two components of foamable polyurethane and/or thermoplastic polyurethane materials having different density, comprising the steps of: - casting in a first mould (20) a first foamable polyurethane and/or thermoplastic polyurethane material with a Shore A hardness greater than 25 to make a first supporting element comprising at least one hull-shaped portion extending for at least 40% of the first supporting element (2) at a rear portion of said first supporting element (2); said hull- shaped portion (4) comprising a cavity defined at least partially by perimeter edges having a height greater than 2 mm; - closing the first mould (20) with a lid (20'); - opening said first mould (20) after at least one stabilisation time of at least 120 seconds; - extracting the first supporting element (2) from said first mould (20); - inserting the first supporting element (2) into a second mould (21); - casting in said second mould (21) a second foamable polyurethane and/or thermoplastic polyurethane material with hardness less than at least 15 % with respect to the hardness of the first foamable polyurethane and/or thermoplastic polyurethane material so that said hull-shaped portion (4) of the first supporting element (2) accommodates, at least partially, said second foamable polyurethane and/or thermoplastic polyurethane material to make a second supporting element (3) coupled to the first supporting element (2).
