Abstract:
The present invention relates to a method for the production of plastic footwear (10; 100) of the “full plastic” type by means of moulding using a polyurethane mixture (M; P). The method comprises the steps of: —providing a mould (20) having a mould cavity (22) defined by at least two impressions (28, 30) and designed to receive a shoe last (24) so as to define, when the mould (20) is closed, an interspace (26) having the shape and dimensions of the plastic footwear (10; 100) to be produced; —spraying a polyurethane mixture (M, P) onto said at least two impressions (28, 30) of the mould cavity (22); —inserting the shoe last (24) inside said mould cavity (22); —closing the mould cavity (22) so that the sprayed polyurethane mixture (M, P) occupies said interspace (26); —opening the mould (20), once at least the demoulding time (td) for the sprayed polyurethane mixture (M, P) has lapsed, such that the sprayed polyurethane mixture (M, P) has solidified inside the interspace (26) forming said plastic footwear (10, 100); —extracting the shoe last (24) from the mould cavity (22); —removing the plastic footwear (10, 100) from the shoe last (24).
