摘要： 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).

摘要： Method for applying an insert 40 of polymer material onto a support layer 30, 30a, comprising the following steps: providing a mould 10 comprising at least one base 12 and at least one cover 18; the base 12 and the cover 18 being suitable for defining with the facing surfaces 13, 17, when the mould 10 is closed, a mould impression 16 which is delimited perimetrally by a closing edge 14; spraying a polymer mixture M in the fluid state onto one of the two facing surfaces 13, 17 of the mould 10; introducing the support layer 30, 30a between base 12 and cover 18 of the mould 10 so that, when the mould 10 is closed, the support layer 30, 30a projects from the closing edge 14; pressing the cover 18 of the mould 10 onto the base 12; opening the mould 10 in order to remove the support layer 30, 30a and the associated insert 40; trimming the portion S of the polymer mixture M which, following the spraying and pressing steps, has flowed outside the external perimeter of the impression mould 16. Finally, the invention relates to a mould 10 which can be used to implement this method and the articles 20 which may be obtained by means of this method.

摘要： A mould for producing footwear by direct injection onto an upper of a sole, including a tread and a midsole, wherein the midsole is composed of a first layer and a second layer. The mould includes a base, a pair of first half-rings, a lid, a pair of second half-rings and a mould last. The first half-rings are designed to be arranged close together such that they abut against the base and against the lid, so as to form a first mould cavity for moulding the first layer (6) of the midsole. While the first half-rings are abutting against the base, the second half-rings are designed to be arranged close together, such that they lie over the half-rings and abut against the upper, fitted onto the mould last, so as to form a second mould cavity for moulding the second layer of the midsole. The first half-rings are provided with guiding means so that they can be moved away from and towards each other and rotate about an axis of rotation. Also a method for producing footwear by direct injection onto an upper, which may be performed by means of the mould.
