MANUFACTURING PROCESS FOR MOLDED FOOTWEAR
The present disclosure describes molded footwear including a sole integrally connected to an upper. For example, a sole structure may include an insole and a strobel board. The insole may include a spacing structure that rests on a top surface of the strobel board to form a cavity between the insole and the strobel board. Further, the upper and/or strobel board may include perforations at least partially aligned with the cavity. Accordingly, the sole structure may be connected to the upper via injection molding material into the cavity formed between the insole, the strobel board, and the upper. The molding material may flow through the specifically located perforations in the shoe's upper and/or the shoe's strobel board such that the material bonds internally within the cavity, internally within the perforations, and externally to the shoe's upper and strobel board but within the mold cavity.
Footwear component manufacturing system
A system including an injector, a press, and a robotic conveyance is used to form a physically foamed article of footwear component from a single-phase solution of a polymeric composition and a supercritical fluid. The parameters and features of the system are configured for the formation of the footwear component in an automated manner with enhanced throughput by the system.
FOOTWEAR MOLD ASSEMBLY FOR INJECTION-MOLDING
Tooling and components of an injection-molding system may be used to mold a foam article. The tooling and components may include features that control parameters of the injection-molding and foaming process, such as temperature, pressure, shot size, shot placement, and the like.
FOOTWEAR MOLD SYSTEM FOR INJECTION-MOLDING
Tooling and components of an injection-molding system may be used to mold a foam article. The tooling and components may include features that control parameters of the injection-molding and foaming process, such as temperature, pressure, shot size, shot placement, and the like.
Skate or other footwear
A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured. Other articles of footwear are also provided.
Shoe manufacturing
Example shoe manufacturing methods and related computer readable medium for implementing a portion of said manufacturing methods are disclosed herein. In some examples, the method includes placing an upper member about an upper portion of a last, wherein the last is a form for the shoe. In addition, the method includes producing a lasting based on data relating to a foot of a user, and attaching the lasting to the upper member, wherein the lasting extends over a lower portion of the last. Further, the method includes molding a sole onto the lasting and the upper member, and removing the last from the upper member.

The parameters and features of the system are configured for the formation of the footwear component in an automated manner with enhanced throughput by the system.
Foam compositions and uses thereof
Components for articles of footwear and athletic equipment including a foam are provided. The foam portion of the components and articles include a composition which includes a thermoplastic copolyester, the composition having a foam structure. A polymer layer is provided on at least on surface of the foam portion. The polymer layer can control or reduce the water uptake of the foam portion. Methods of making the compositions, foams, and components are provided, as well as methods of making an article of footwear including one of the foam components. In some aspects, the foams and foam components can be made by injection molding, or injection molding followed by compression molding.
Mould, machine and method for manufacturing three-dimensional items and manufacturing plant associated with same
A mould for manufacturing three-dimensional items, comprising a body; a lid configured to close the body; and incorporated closing and openings configured to keep the body and the lid joined during the movement thereof is disclosed. A machine for manufacturing three-dimensional items, comprising a receiving module configured to receive the mould; a conditioning module configured to receive the mould from the receiving module and act on the incorporated closing and openings in order to separate the lid from the body; and a handling module configured to receive the body from the conditioning module and enable the placement of the components of the item to be manufactured. A method for manufacturing three-dimensional items and manufacturing plant associated with the machine.
Foam article with enhanced properties
A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.
