Abstract

La présente invention concerne une botte de neige à fourrure intégrée et son procédé de fabrication. Le procédé de fabrication comprend les étapes de : découpe des matériaux (S1), découpe d'une surface de capuchon d'orteils de taille standard (14), une surface de cylindre avant (13), une surface de cylindre arrière (12), une surface de manchon arrière et un intérieur de manchon arrière ; cisaillement de fourrure (S2), cisaillement de la fourrure de la surface de capuchon d'orteils (14), la surface de cylindre avant (13), la surface de cylindre arrière (12), la surface de manchon arrière et l'intérieur de manchon arrière ; la couture (S3), de manière à coudre la surface de capuchon d'orteils cisaillée (14), la surface de cylindre avant (13), la surface de cylindre arrière (12), la surface de manchon arrière et l'intérieur de manchon arrière conjointement de façon à former une tige (1), et un contrefort arrière étant disposé entre la surface de manchon arrière et l'intérieur de manchon arrière ; le raccordement de la tige et de la couture (S4), la couture d'une première semelle intercalaire (15) et de la tige (1) conjointement pour former une empeigne ; le moulage par injection d'une semelle (S5), le moulage par injection du matériau PU et l'empeigne d'une seule pièce par une machine de moulage par injection et la formation une semelle PU sur la face inférieure de l'empeigne. Les problèmes en ce qu'une semelle de chaussure de neige est non collée, le degré de souplesse et de confort de la semelle de la botte de neige sont réduits, et la résistance à l'usure est faible sont efficacement résolus.
