The present disclosure relates to a coating method and a coating device, configured to place a surface material on the surface of an object. The coating method includes: obtaining a three-dimensional image of the object by a scanning element providing a structured light, sequentially moving the nozzle according to the pixels of the three-dimensional image, and spraying the surface material on the surface of the object. The coating device includes a structured light scanning element, providing a scanning light beam to the object and capturing a three-dimensional image; a processing unit; and a nozzle. The processing unit is electrically connected to the structured light scanning element and the nozzle. The processing unit receives the three-dimensional image, moves the nozzle according to the pixels of the three-dimensional image, and sprays the surface material onto the surface of the object.

An adhesive applicator includes an actuation axle, a first hub unit, a second hub unit, a plurality of elastic members, and a pliable dispenser web. The first and second hub units are mounted on the actuation axle to be spaced apart from each other, and to rotate with the actuation axle about a rotation axis. Each of the elastic members is disposed between the first and second hub units, and has a radial elastic force relative to the rotation axis. The pliable dispenser web is configured to wrap around the elastic members, and can be deformed in compliance with a topology of an attachment region of a shoe component against the radial elastic force.

A method for preparation of a part of a surface of a shoe for subsequent gluing comprises the steps of spreading a glue on the operating surface of a roughing tool and applying this operating surface onto the part of the shoe to be roughed before drying of the glue, so as to transfer the glue onto the part of the surface being roughed. A device (14) implementing this method and a machine (10) using this device are also described.

A self-cleaning ring conveyor includes a first roller having a first rotational axis and a second roller having a second rotational axis that is parallel with the first rotational axis. The conveyor also includes a first ring extending around a combination of the first roller and the second roller and a second ring extending around the combination of the first roller and the second roller. The first ring and the second ring are parallel to each other. The conveyor also includes a first scraper having a first scraping slot and a second scraping slot. The first ring extends through the first scraping slot and the second ring extends through the second scraping slot.

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 method for coupling a non-trimmed sole and an upper for making a shoe, which includes the steps of providing a non-trimmed sole having a flat and/or sheet-like shape and provided with a first surface, adapted during use to face towards the upper, wherein the non-trimmed sole includes a central part or impression and an edge portion which is extended outward starting from a peripheral portion of the impression, positioning the sole in a position below the upper, moving the non-trimmed sole so to enclose at least part of the upper, constraining the non-trimmed sole and at least part of the upper so as to obtain the shoe; shoe obtainable by such method.

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.

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.
