A FOOTWEAR INJECTION MOULD
20220279893 · 2022-09-08 ·

A footwear injection mold includes a secondary injection mold defining at least part of an injection chamber. The injection chamber includes a proximal surface defining a part of a distal surface of a footwear part. The secondary injection mold includes a protrusion having an upper contacting surface, a proximal end, a primary surface faced away from the injection chamber, and a secondary surface facing the injection chamber. A normal of the upper contacting surface intersects a center point of the upper contacting surface. A protrusion plane is defined by the normal of the upper contacting surface along a width of the protrusion, and defines a boundary between a primary half and a secondary half of the protrusion, the primary half arranged between the protrusion plane and the primary surface, and the secondary half arranged between the protrusion plane and the secondary surface. A height of the proximal end of the protrusion is larger than the height of the upper contacting surface of the protrusion, relative to the normal of the upper contacting surface.

Disclosed herein is a process for making a shoe using a stand-alone mouldable nonwoven fabric which has the ability of self-sustaining and shape maintenance and which is heated to become softened till molten. In the process of the invention, the shoe parts are moulded by a compression moulding process and the moulded parts are then heated and welded together by a plastic welding method.

Article of footwear and method of manufacturing an article of footwear
11129441 · 2021-09-28 · ·

An article of footwear includes an upper and a strobel stitched to the upper at a series of stitches disposed in stitch holes that extend through the strobel. The strobel and the upper define a foot-receiving cavity with an inner surface of the strobel disposed at the foot-receiving cavity. A midsole is secured to the upper and an outer surface of the strobel is disposed at the midsole. The stitch holes are obstructed such that the stitch holes are not exposed to both the midsole and the foot-receiving cavity. Accordingly, when a flowable polymeric material is injected in a mold cavity to form the midsole with the lower portion of the upper and the strobel in the mold cavity, the stitch holes will not provide a path for entry of the flowable polymeric material into the foot-receiving cavity. A method of manufacturing an article of footwear is disclosed.

SHOE AND METHOD OF MANUFACTURING SHOE

A shoe includes: an upper member containing a knit fabric, a knit-like fabric, and/or a woven fabric as a primary member and forming a part of a medial side surface, a part of a lateral side surface, and a part of a back surface; an outsole member made of thermoplastic resin and forming a bottom portion including a contact surface, and a peripheral portion attached at least partially to respective lower parts of the medial and lateral side surfaces and a lower part of the back surface and connected to the bottom portion; and a sock liner inserted in interior space defined by the upper member and the outsole member. The upper member defines an opening at which at least a part of the lateral side surface is cut. The outsole member includes a window portion covering the opening. The window portion is made of a semi-transparent material that makes at least a part of a lateral side surface of the sock liner in the interior space visible through the window portion covering the opening.

Thermoplastic non-woven textile elements

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

FOOTWEAR AND SOLE STRUCTURE ASSEMBLIES WITH ADHESIVE-FREE MECHANICAL ATTACHMENTS BETWEEN INSOLES AND MIDSOLES
20210076774 · 2021-03-18 · ·

Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.
