    Invention background
    The present invention relates to the technical field of methods for manufacturing a component for a shoe or a shoe.
    EP 2 815 668 A1 relates to a method for manufacturing a shoe comprising a first step of manufacturing the molded upper during which a rigid foot-shaped core is covered by a member of the upper and then placed in a mold . A resin is then injected into said mold according to a mask covering all or part of the rod. The rod thus prepared is then placed in a mold for the manufacture of the outer sole by injection of a resin directly on the underside of the rod. This process makes it possible to fabricate and assemble the upper and sole of a shoe in a simplified manner without sewing.
    WO 2014/130598 A2 relates to a method of manufacturing the upper of a shoe comprising the arrangement of a upper on a rigid perforated core disposed on a tray. A deformable waterproof membrane is placed on the rod placed on the core, then the membrane is pressed against the rod and therefore the core under the effect of the suction of air through the perforations in the core. During this step, the core is heated so that the rod possibly adheres to another element at least partially thermally fusible. This process makes it possible to manufacture a rod while avoiding seams but it is not suitable for securing at the same time a sole to the rod.
    FR 3 007 317 A1 relates to a method of manufacturing an upper of a shoe comprising the arrangement of a upper on a rigid core, then of a waterproof membrane on the upper, the assembly being placed in an enclosure in which evacuation is carried out so as to press the membrane on the core and therefore the rod.
    The foregoing methods seek to reduce the number of steps required in the construction of a shoe, in particular by eliminating sewing steps consisting in attaching the upper to a sole. Indeed, the soles are traditionally in the state of the art secured to the uppers using a mounting called Strobel during which the various sole elements (insole, midsole and outsole in particular ) are pasted. However, in the previous methods in which the sole is secured to the upper during the making of the upper and / or the sole, the sole-upper assembly has poor resistance to delamination, the sole tending to become detach from the stem. This drawback is amplified when the sole is subjected to forces tending to move it away from the upper. This phenomenon is observed in particular when the sole includes projections on its underside engaging with the ground, for example for shoes for the practice of football or hiking.
    Subject and summary of the invention
    The present invention relates, according to a first aspect, to a method of manufacturing a shoe, characterized in that it comprises the following steps:

    The preform may be a rigid part or a flexible envelope, in particular a sealed envelope, configured to be inflated.
    When the preform is in a flexible envelope, the method according to the invention comprises inflation means making it possible to inflate the flexible envelope and to press it against the internal walls of the first main liner. Preferably, the assembly is then sandwiched between the inflatable envelope and the counter-mold.

    Detailed description of the invention
    The first main liner 5 shown in FIGS. 1 and 2 comprises a sole part 10, a forefoot part 15, a lateral part 20, a medial part 25 and a rear part 30. The first main liner 5 is in particular in a unitary knitted textile envelope 35, in particular with picked stitches, having an internal volume 40 configured to receive the foot of the user. The rear 30, lateral 20, medial 25 and forefoot 15 portions project vertically from the plane P comprising the sole portion 10. The lateral 20 and medial 25 portions are arranged between and in connection with the rear portions 30 and forefoot 15.
    The forefoot portion 15 includes in the instep area 18 first and second sets of lacing through openings 45, 50. Each first and second set of lacing through openings 45, 50 includes five sets of two openings 55, 60, the two openings 57, 58; 67, 68 of each set 55, 60 being separated by a knitted portion forming first and second bridges 70, 75. The first bridges 70 and the second bridges 75 are substantially aligned by sets of openings 55, 60 in a transverse direction T substantially perpendicular to the longitudinal axis L of the first main liner 15.
    The forefoot part 15 also comprises in the instep area 18, a set of through ventilation openings 80, in particular disposed between the two sets of through opening lacing 45.50. The set of ventilation openings 80 is arranged in an area of the first main liner 15 substantially centered between the medial 25 and lateral portions 20. The set of ventilation openings 80 comprises for example ten through openings.
    The first main liner 5 represented in FIG. 1 comprises at the region for the introduction of the foot 16, an area in the form of a closed collar 90, in a mesh type of the rib type η X p, n and p being integers other than 0 and less than or equal to 5, for example lxl, or 1x2 dimensions. This zone 90 thus forms a flexible and elastic border facilitating the introduction of the foot.
    The first main liner 5 is secured to a outsole 100 comprising a set of cleats 105, in particular arranged for the practice of football, projecting from its external face 101.
    As illustrated in Figures 7 and 8, the first main liner 5 is disposed on a rigid preform 110 in the shape of a foot. It is possible to have a lace in the first and second sets of lacing through openings 45, 50 in order to facilitate the positioning and plating of the first main liner 5 on the preform 110. Then, the sole portion 10 of the first liner main 5 is placed in a counter-mold 130 (in one or two parts) so that the external face of the sole part 10 projects into the interior volume of the counter-mold into which a polymer composition is injected for the manufacture of the outsole 100. The preform 110 is removed from the mold, the first main liner 5 and the outsole 100 comprising studs 105 are thus secured (see FIG. 4). Then, a first auxiliary liner 200 in a textile piece of which at least part or all of it is heat-fusible and at a melting temperature Tl (° C) is placed on the first main liner 5 and the outsole 100 in sort of covering, at least in part, the first main liner 5, the outsole 100, and the junction 150 between the first main liner 5 and the outsole 100. The first auxiliary liner 200 comprises sole parts 210, forefoot 220, medial 230, lateral 240 and rear 250, of which the forefoot parts 220, medial 230, lateral 240 and rear 250 are found in whole or in part respectively against the forefoot parts , medial, lateral and rear of the first main liner 5. The sole portion 210 of the first auxiliary liner 200 comprises a set of zones adapted 260 for receiving the studs 105, said zones 260 are in particular through openings from which the studs 105 are projected. In this specific example, the first auxiliary liner 200 is in an entirely fusible textile piece having a melting temperature T1. Then, the assembly forming the rod 280 comprising the first main liner 5 and the first auxiliary liner 200, is subjected to a heating temperature Te greater than or equal to the temperature Tl so as to obtain the complete melting of the first auxiliary liner 200. Preferably, a heating system is arranged inside the preform 110. The shoe 300 obtained, shown partly in transverse section in FIG. 3, has improved resistance to delamination between the outsole 100 and the first main liner 5 since the junction 150 is covered with a polymer film 400 revealing in relief the textile appearance of the first main liner 5. It is also possible, in a complementary manner, to arrange the assembly forming upper 280 in a mold whose internal face is engraved so as to impart one or more pattern (s) determined to the polymer film 400 according to the regions of the assembly forming upper 280 of shoe 300.
    The first main liner 5 is in a knitted textile envelope with three-dimensionally picked stitches leaving a circular or rectilinear knitting loom, in particular rectilinear. In this specific example, the first main liner 5 is knitted with multi-filament yarns of polyethylene terephthalate of 500 dtex for approximately 204 filaments. The mass of the first main liner 5 is between 100 g / m 2 and 250 g / m 2 , in particular of the order of 170 g / m 2 .
    The first auxiliary liner 200 is in a knitted fabric piece with picked stitches (in three dimensions) on a circular knitting loom from mono component single filament yarns, in particular made of polyurethane, the diameter of which is between 0.10 mm and 2 mm, in particular of the order of 1 mm. The first auxiliary liner 200 may include zones whose density of threads varies so as to create zones having a thickness greater than those of other zones and therefore ultimately a film 400 having zones of greater thickness.
    The mass of the first auxiliary liner 200 is between 30 g / m 2 and 200 g / m 2 , in particular of the order of 50 g / m 2 .
    The outsole 100, including the studs 105, has a mass of between 100 g / m 2 and 400 g / m 2 . The final mass of shoe 300 finally depends on the size of the shoe, it is in particular between 200 and 250 g / m 2 (including laces), in particular for a European size 43.
    The outsole 100 is in this example made of an elastomeric material, in particular made of TPU.
    Figure 5 shows in section another example of shoe 500 according to the invention. The shoe 500 comprises a first main liner 600 preferably whose melting or decomposition temperature is higher than the temperature Te, a first auxiliary liner 700 preferably entirely thermally fusible (Tl less than Te), a second main liner 800 preferably whose melting or decomposition temperature is higher than the temperature Te, a second auxiliary liner 900 preferably integrally heat fusible (T2 less than Te) and a outsole 550 comprising crampons 560. The first and second main liners 600 , 800 and the first and second auxiliary slippers 700, 900 each include rear, sole, forefoot, medial and lateral parts.
    The outsole 550 is preferably overmolded, in particular by injection as described with reference to FIGS. 7 and 8, on the external face 615 of the sole part 610 of the first main liner 600.
    The first main liner 600 secured to the outsole 550 and disposed on a rigid preform (as described above with reference to shoe 300), and possibly heated, is covered with a first auxiliary liner 700 , a second main liner 800 then a second auxiliary liner 900 defining an assembly forming a rod 950. The sole portions of the first and second auxiliary liner 700, 900 and the second main liner each comprise a set of zones suitable for receiving the studs 560, in particular through openings through which the studs project. The junction 580 between the outsole 550 and the first main liner 600 is thus completely covered by two layers of polymer films from the first and second auxiliary liners 700, 900 and the textile envelope of the second main liner 800 thus further improving the resistance to delamination.
    The first main liner 600 in this specific example comprises first and second sets of through openings to form lacing loops similar to those 45.50 supported by the first main liner 5 (by their structures and their placements) but does not include no ventilation openings 80. The second main liner 800 includes ventilation openings similar to those 80 of the first main liner 5 (by their structures and their placements).
    It is also possible (not shown) that the second main liner 800 also includes said first and second sets of through openings to form lacing loops, which first and second sets are then not present on the first main liner 600.
    Furthermore, in this embodiment, the second main liner 800, the second auxiliary liner 900, and the first auxiliary liner each comprise in their forefoot region at least one lacing opening, in particular two sets of openings lacing arranged on either side of the instep area and arranged so as to cooperate with the lacing loops of the first main liner so as to project through the lacing openings. A lace 990 is passed through the lacing openings, as can be seen in the figure
    6. The junction 580 between the outsole 550 and the first main liner 600 is invisible. Preferably, with the exception of studs 560, the outsole 550 is not visible.
    The first and second main liners 600, 800 may be the same or different.
    The first and second auxiliary shoes 700, 900 may be identical or different, and in particular similar to the first auxiliary shoe 200.
    FIG. 9 represents a shoe 301, which is a variant of shoe 300, in which the first main liner 51 comprises a first region 52, in particular forming a housing, knitted integrally with the latter 51 and projecting from the internal face 12 of the sole portion 11 in the interior volume 53 of the first main liner 51. During the manufacture of the outsole 102 by injection molding for example, the injected polymer composition intended to form the outsole 102 flowed into the housing 52 knitted and fills said housing 52 thus forming a damping element and / or a fastening member.
    The first main liner 51 may include a first knitted region 52 disposed in the heel region of the sole portion 11 and / or a first knitted region 52 disposed in the forefoot region of the sole portion 11. Said member fastener can cooperate with a complementary fastening member supported by a sockliner for example for their removable fastening.
    FIG. 10 represents a first main shoe 1000 in connection with an additional shoe 1100 at their respective opening apertures 1010, 1110 of the foot.
    The first main liner 1000 is shown secured to the outsole 1050 provided with studs 1055. The additional liner 1100 can thus be folded into the interior volume 1020 of the first main liner 1000 and thus forms a welcome liner. The additional liner 1100 can also act as first or second auxiliary liner or even as second main liner within the meaning of the present invention. In the latter, it is necessary to have a first auxiliary liner between the first main liner 1000 and the second main liner formed by the additional liner 1100.
