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 (11a) 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 (11a) 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.

The manufacturing of articles relies on the bonding of two or more components to form some forms of the articles, such as a shoe sole bonded with a shoe upper. The bonding may be achieved with an adhesive particulate that is applied to a surface of a substrate. The adhesive particulate is selectively fused to the substrate with a controlled energy source, such as a laser. The selective application of laser energy allows for specific geometric structures of adhesive particulate to be formed on the substrate. The substrate having the fused adhesive particulate is mated with another component allowing the fused adhesive particulate to bond the first substrate and the second component.

Systems apply a material (e.g., adhesive) to an article (e.g., a component in an article of footwear) with a multiple-nozzle tool. A first nozzle of the multiple-nozzle tool is effective to provide an edge application of the material that is consistent in application of the material. A second nozzle of the multiple-nozzle tool is effective to provide a greater material coverage application than the first nozzle. The second nozzle may be implemented to apply the material at an interior area from the edge at which the first nozzle applies the material, in an exemplary aspect.

A method for joining a sole element with an upper element includes the steps of (a) operating a positioning system to position the sole element and the upper element in a defined first position with respect to each other, (b) operating the positioning system to position the sole element and the upper element in a second position for applying a joining agent to the sole element and/or the upper element and (c) joining the sole element with the upper element by operating the positioning system to position the sole element in contact with the upper element in a third position of the positioning system, wherein the third position is defined with respect to the first position.

A shoe making method includes adhesion of an outsole and a midsole, and adhesion of a sole and a vamp. When the outsole and the midsole are attached, an upper adhesion surface of the outsole is processed by coating absorbent and by spraying powder adhesive, while a lower adhesion surface of the midsole is processed by spraying two-in-one primer, to achieve a one-side cementing. When the sole and the vamp are attached, an upper surface of the sole is processed by coating absorbent and by spraying powder adhesive, while a lower adhesion surface of the vamp is processed by spraying two-in-one primer, to achieve a one-side cementing. The powder adhesive is uncharged powder adhesive which is directly sprayed by a machine, without needing static attachment. The two-in-one primer is made of reinforcer and glue.

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.
