Shoe uppers having smooth seams and methods for producing them are disclosed. In one embodiment the upper uses thermoplastic seam tape which forms bonds between contiguous upper sections after being subjected to heat and / or pressure. In another embodiment, different parts of the shoe can be joined using hidden seams. Close seams can also be covered with a transfer material adapted to give the interior and / or exterior of the upper a smooth surface. In yet another embodiment, a method is disclosed which allows three-dimensional upper sections to be bonded on a last using thermoplastic seam tape.

The invention relates to sole elements and methods for manufacturing sole elements for shoes, in particular for sport shoes, with a specific density distribution in a transverse and / or longitudinal direction. The methods include the steps of manufacturing a sole element preform from a polymer material with a thickness varying in the transverse and / or longitudinal direction depending on the desired density distribution and the press-forming of the sole element preform in a forming tool to form the finished sole element from the sole element preform.

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.

The invention relates to a shoe sole press-fit device, in particular to a rapid shoe sole press-fit device for shoe production. The technical problem to be solved in the invention is to provide the rapid shoe sole press-fit device for shoe production which is good in press-fit effect, easy to operate and high in working efficiency. In order to solve the technical problem, the rapid shoe sole press-fit device for shoe production provided by the invention comprises a bottom plate, a left side plate, a motor, a right side plate, a rotating shaft, a big belt pulley, a placement plate, an upper bearing block, a lower bearing block, a lead screw, a nut, a small belt pulley, a flat belt, a top plate, a driven wheel, a gear, a first spring, a sliding rail, a slide block, a connecting rod, a rack, a cam, a guide plate, a lifting rod, a movable plate, a pressure block, a driving wheel, a first belt and the like. According to the rapid shoe sole press-fit device for shoe production provided by the invention, with the adoption of a manner of the pressure block and the placement plate, the pressure block moves up and down to press the shoe sole with glue on the placement plate.

A breathable shoe, including: an upper assembly (10;310;410) having a breathable upper (11;311;411); a membrane (14;314;414) made of a material which is waterproof and breathable, and a sole (16;116;216;316;416) made of perforated elastomer, which are all mutually attached such that the membrane is arranged between the upper assembly and the sole, and the sole is sealed perimetrically to the membrane, in a manner to prevent moisture to enter into the upper assembly from the sole through the membrane, and to permit moisture to leave the inside of the upper assembly through the membrane and through the sole. In one preferred embodiment, the membrane is first attached to the upper assembly so that the upper assembly is a unitary upper assembly including the membrane, and such unitary upper assembly is subsequently attached to the sole.

The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second. The inflatable article or bladder of the present invention may be used as or in athletic equipment, for example, including footwear.

The invention relates to an automatic production line for shoes. The automatic production line comprises an automatic vamp gluing device and an automatic sole gluing device. The automatic vamp gluing device comprises a first conveying belt, a first driving assembly and a first automatic glue spraying control assembly. The first automatic glue spraying control assembly comprises a three-dimensional scanning mechanism, a first processing water spraying mechanism, a first processing water drying mechanism, a first glue spraying executing mechanism and a first glue drying mechanism, wherein the three-dimensional scanning mechanism, the first processing water spraying mechanism, the first processing water drying mechanism, the first glue spraying executing mechanism and the first glue drying mechanism are located above the first conveying belt and adjacently connected in sequence. The first glue spraying executing mechanism comprises a controller, a first six-degree-of-freedom mechanical hand and a first spray gun, wherein the enable end of the controller is connected with the three-dimensional scanning mechanism, and the first spray gun is installed on the arm of the first six-degree-of-freedom mechanical hand.

A system and method may simultaneously apply a limited visibility bite line to a temporarily assembled shoe upper and shoe sole while also generating a digital bite line. The digital bite line may be used to generate a tool path for the application of adhesives to the shoe upper and / or to the shoe sole assembly to permanently assemble the shoe. The limited visibility bite line may comprise a mark or other indicia observable only under specific viewing conditions and / or only for a limited amount of time or until removal. The limited visibility bite line may be used for quality control check purposes to verify, for example, the proper application of adhesives or the proper assembly of the shoe. The limited visibility bite line may be unobservable to the ultimate purchaser and / or wearer of the shoe.
