Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated manner. For example, shoe parts may be retrieved and temporarily assembled according to preset relative positions to form part stacks. The part stacks may be retrieved with the relative positioning of the shoe parts being maintained and placed at a stitching machine for more permanent attachment via stitching of the parts to form a shoe assembly. Movement during stitching of a conveyance mechanism that transfers the part stack from the stacking surface to the stitching machine and movement of a needle associated with the stitching machine may be controlled by a shared control mechanism such that the movements are synchronized with respect to one another. Vision systems may be leveraged to achieve movement and position information between and at machines and locations.

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, methods, and computer-readable storage media for applying an adhesive film to the sole of shoes. Application of a portion of the adhesive film can be performed by receiving a shoe on top of the adhesive film, which in turn is above a plate and compressible pins. Upon receiving the shoe, the plate is raised or lowered, and the compressible pins mark the perimeter of the sole of the shoe. The adhesive film is cut in a sole-shaped pattern due to the height differentiation, resulting in a sole-shaped portion of the adhesive film being adhered to the sole of the shoe.

This document relates to adhesive application devices and methods for applying an adhesive on a shoe during manufacturing.

A machine (10) for applying glue onto a sole of footwear comprises a support (17) for a sole and a glue dispensing device (14) and a movement system (13) for moving the device (14) relative to the support (17) under the control of a control system (15) so as to follow, with the device (14), gluing paths along a sole placed on the support (17). The glue dispensing device (14) comprises a radial brush (30) which is motorized to rotate about its central axis (31) and is designed to pass lightly with its radial periphery along a sole to be glued placed on the support (17), and a dispensing unit (33) designed to dispense glue on the periphery of the radial brush (30). Advantageously, the brush (30) is kept with its axis substantially parallel tangentially to the edge of the sole during operation of the machine for gluing the edge of the sole.

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.

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 of preparing shoe components includes the steps of: providing a first shoe component and a second shoe component, forming an adhesive member on one of the first and second shoe components, stacking the first and second shoe components such that the adhesive member is disposed therebetween, heating to melt the adhesive member so as to adhere the first and second shoe components to each other, and suctioning air to adhere the first and second shoe components closely to each other.
