A nozzle dispenses a material, such as an adhesive, primer, paint, or other coating, through a dispensing port on to a substrate. The spray pattern provided by the nozzle defines, at least in part, an application pattern of the material on to the substrate. An air mask port integral with the nozzle or a separate nozzle expels a mask stream of pressurized gas. The mask stream projects toward the substrate to aid in limiting an application of the material beyond an application line on the substrate. The air-mask port and the dispensing port may be moved relative to the substrate and/or the application line such that the mask stream provides a barrier to the material being applied.

A shoe manufacturing system (100) processes a to-be-bonded surface (11a) of an upper (11) before bonding a sole to the upper (11). The shoe manufacturing system (100) includes a holding platform (10), a camera (20a, 20b), an applicator (30), a robot arm (40), and a control device (60). The control device (60) identifies a boundary of the to-be-bonded surface (11 a) of the upper (11) that is to serve as a master model M among a plurality of uppers (11), for defining an area of the to-be-bonded surface (11 a) to be processed, based on three-dimensional shape data of the master model M acquired by the camera (20a). The control device (60) controls the robot arm (40) for each of the uppers (11) (such as products P1 to P3) other than the master model M, to cause the applicator (30) to apply an adhesive to the area of the to-be-bonded surface (11a) enclosed by the identified boundary.

An article of footwear includes an upper assembly having a foot insertion volume. The foot insertion volume includes a proximal part and a lateral part. A first layer and a second layer each have a lateral surface and a medial surface, respectively. The second layer is positioned between the foot insertion volume and the medial surface of the first layer. A sole assembly includes an upper facing surface and a ground contacting surface. The upper facing surface is connected to the proximal part of the upper assembly. A peripheral part of the sole assembly overlaps a proximal part of the first outer layer and/or the second layer. The first outer layer includes a through-going opening extending from the lateral surface and towards the medial surface. A part of the overlapping material of the sole penetrates the opening to bond to the second layer.

A present invention related to a method for manufacturing a dot bonding shoe insole using an adhesive resin containing hydrophobic nano-silica, including: melting adhesive resin made of any one selected from thermoplastic polyurethane (TPU) or ethylene vinyl acetate (EVA) containing hydrophobic nano-silica in the range of 0.2 to 5 phr and applying to the surface of the transfer roller in which the intaglio dot pattern is formed in a mesh shape in the shape of the shoe insole; removing the adhesive resin applied other area than the intaglio dot pattern of the surface of the transfer roller; transferring the adhesive resin applied to the intaglio dot pattern of the surface of the transfer roller to either one of the foam or the fabric; bonding the foam and the fabric by compressing; and cutting a shoe insole shape in a package in which the foam and the fabric are bonded.

Systems and methods of manufacturing a shoe outsole are provided wherein at least a portion of the resulting shoe outsole includes embedded particles. An example method includes applying adhesive to at least one region of the shoe outsole, depositing selected particles onto the adhesive to provide the shoe outsole with a first coat of particles, and at least partially curing the adhesive. The method continues by applying additional adhesive over the first coat of particles, depositing additional particles onto the adhesive to provide the shoe outsole with a second coat of particles, and at least partially curing the subsequent application of adhesive.

A process for manufacturing a waterproof and vapor-permeable shoe is provided. In the process, an adhesive layer is provided on a knitted fabric to form a laminate, and a shoe upper unit is formed from the laminate, and has an adhesive component defining an inner space of the shoe upper unit. A shoe lining member, which is worn on a last, is placed into the shoe upper unit to permit a knitted component of the shoe upper unit to be bonded to the shoe lining member through the adhesive component under a heating treatment.
