The negative pressure generation system can cause the compression material to expand to allow for insertion of the article into the interior portion of the compression material.

Shoe with knit upper having thermoplastic yarn regions

A shoe includes a knit upper and a sole secured to the knit upper. The knit upper is formed with a first type of knit structure knitted with a thermoplastic yarn in a first area. The first area is in at least the toe region of the knit upper. In a second area including at least the medial and lateral metatarsal regions of the knit upper, the knit upper is formed with a second type of knit structure knitted with a second yarn having a higher melting temperature than the thermoplastic yarn. A rear boundary line of the first area and a forward boundary line of the second area define a boundary line between the first and second areas.

A multi-layer decorating element includes a base and a plurality of plates forming decorative elements. The base has a length between the first and second ends thereof and an increased width from the first end to the second end. The first end of the base is curved. The second end of the base is divided by a gap into two segments. The gap has a closed end and an open end. The open end is disposed at the second end of the base. The closed end has a smaller width than the open end. The plurality of plates includes a side with a hot melt glue layer and is hot pressed on a side of the base. The plurality of plates is disposed within peripheral edges of the base and includes a plurality of overlapped sections. The plurality of plates has different shapes.

Multi-layer extruded uppers for articles of footwear and other foot-receiving devices

Upper components for footwear include: (a) a first upper component that includes a first layer having a first material as a first filament including first plural, non-intersecting, spaced apart path segments (wherein the first filament has a width dimension of less than 3 mm wide (and in some examples, less than 2 mm wide, less than 1.5 mm wide, less than 1 mm wide, or even less than 0.75 mm wide)); and (b) a second upper component including a fabric element formed at least in part of a fusible material, wherein the fusible material of the second upper component is fused to the first material of the first upper component (e.g., in an adhesive-free manner). Additional layers of material, including additional layers including filament and/or fabric elements, e.g., of the types described above, may be included in the upper.

Shoe with multilayer upper

A shoe including a sole and an upper. The upper is coupled to the sole. The upper includes an outer layer and an inner layer. The outer layer has an outer surface and an inner surface. The inner surface of the outer layer is in direct contact with the inner layer. The outer layer is a hot melt thermoplastic material, and the inner layer is a material different from that of the outer layer. At least a portion of the outer layer is adhered to the inner layer, and the inner layer including a portion not covered by the outer layer.

THREE-DIMENSIONAL FLEXING RESISTANCE WATERPROOF AND MOISTURE-PERMEABLE SHOE UPPER AND PREPARATION METHOD THEREFOR

A three-dimensional flexing resistance waterproof and moisture-permeable shoe upper, including fabric, waterproof and moisture-permeable membrane, and eco-friendly adhesive is provided. The waterproof and moisture-permeable membrane is closely bonded with an inner layer of the fabric. The outer layer and inner layer of the fabric are closely bonded together through eco-friendly adhesive, which is bonded with the fabric in a mesh structure. The eco-friendly adhesive includes liquid adhesive or powder adhesive. The shoe upper is shaped by the heating method which includes vacuum heating, electric heating or steam heating. The outer layer of the fabric is closely bonded with the inner layer, so that the defects of the accumulation of sludge, dust and water droplets between the outer layer and the inner layer of the existing shoe upper is overcome, making the shoe upper waterproof and moisture permeable. The three-dimensional shoe upper is formed through vacuum forming method.

Agile manufacturing processes and systems
11700917 · 2023-07-18 · ·

A manufacturing process involving a series of discrete operations can be modified by adding, removing, or reordering operations, without design changes to the equipment. The manufacturing process uses a frame comprising one or more alignment tabs. Each alignment tab comprises an alignment element. The alignment element interacts with a corresponding alignment element at a manufacturing station to identify to the manufacturing station the position and orientation of the frame. The frame supports a material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the pliable material on the frame from the interaction of the alignment elements on the frame and the manufacturing station. The operations at any particular manufacturing station can therefore be positioned independent of what operations, if any, have come before, or in what order.
