Articles of footwear with uppers comprising a wound component and methods of making the same
Articles of footwear and methods of making articles of footwear including one or more continuous threads wound around anchor points. The winding of the one or more continuous threads forms a thread pattern that imparts desired characteristics to components of the article of footwear. Thread lines of the thread pattern may be bonded together. In some embodiments, thread lines may be bonded with a bonding layer.
Direct bottomed article of footwear with a film
An article of footwear has an upper that is direct attached with the sole. The sole has a film extending up sidewalls of the sole to a film edge that is prior to the sidewall and the upper joining. Method of manufacture of the article of footwear includes steps of positioning a film over a mold cavity and then securing the film to the mold. The film is heated and then drawn into the mold cavity under a vacuum. The film forms a liner of the mold cavity. A foam composition is injected into the lined mold cavity. As the foam composition expands, the foam composition interacts with and mechanically engages with the upper that is positioned at the mold cavity to allow for the mechanical engagement that results in the direct attach of the sole to the upper. The film is then trimmed from the sole sidewalls.
Direct bottomed article of footwear with a film mold
An article of footwear has an upper that is direct attached with the sole in a article of footwear mold. The sole has a film extending up sidewalls of the sole to a film edge that is prior to the sidewall and the upper joining. Method of manufacture of the article of footwear includes steps of positioning a film over a mold cavity and then securing the film to the mold. The film is heated and then drawn into the mold cavity under a vacuum. The film forms a liner of the mold cavity. A foam composition is injected into the lined mold cavity. As the foam composition expands, the foam composition interacts with and mechanically engages with the upper that is poisoned at the mold cavity to allow for the mechanical engagement that results in the direct attach of the sole to the upper.
String lasting
A method of lasting an upper for an article of footwear can include inserting a last in a collapsed state into an upper. The last can include at least two parts movable relative to each other so as to allow the last to be collapsed along a substantially longitudinal direction from an extended state to the collapsed state. The last can also include at least one fastener configured for attaching string and configured to hold string in the collapsed state and in the extended state of the last. The method can further include attaching the upper to the fastener using at least one string and extending the last. For example, the act of extending the last may increase tension in the string in a manner that draws the upper about the last.
Shoe upper mounting machine with string lasting means
A shoe upper mounting machine with a string lasting means is designed for mounting a shoe upper using a string lasting means for the footwear mounting sector with high-productivity, using the string lasting method of sewing the edges with a lasting string. The invention includes the use of this technology in footwear models which are normally excluded because they have sturdy, not flexible shoe uppers which are difficult to conform using string lasting. It is sufficient to provide a shoe upper with new dimensions suitable for this mounting technology. The machine is capable of lasting any string and adjusting any shoe upper to the form, provided these materials conform with acceptable quality standards for footwear components. The invention is characterized by a module (3) for fitting shoe uppers onto the form (F), a string lasting module (4), and optionally a module (5) for coupling and uncoupling the couplable footwear form.
MODULAR LAST
A modular last system comprising: a frame and plurality of last segments removably attached to the frame, wherein the plurality of last segments each have an outer surface that defines an anatomical shape.
Footwear strobel with bladder and tensile component and method of manufacturing
An article of footwear includes a strobel that has a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around at least a portion of a perimeter of the interior cavity. A tensile component is disposed in the interior cavity. The tensile component is secured to opposing inner surfaces of the polymeric bladder. The peripheral flange defines a groove extending along the peripheral flange. The groove serves as a guide path for an operator or for a machine to follow when stitching or otherwise securing the strobel to the upper. A method of manufacturing footwear is included.
Footwear strobel with bladder and lasting component and method of manufacturing
An article of footwear includes a strobel that has a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around at least a portion of a perimeter of the interior cavity. A tensile component is disposed in the interior cavity and is secured to opposing inner surfaces of the polymeric bladder. The peripheral flange defines a groove extending along the peripheral flange. The strobel also includes a lasting component configured to extend along the peripheral flange around the at least a portion of the perimeter of the interior cavity. The lasting component is secured to the peripheral flange. A method of manufacturing footwear that includes the strobel is disclosed.
Last with retractable pins
A last assembly includes a plurality of retractable pins and a plurality of vacuum holes, both acting to hold footwear segments to the last assembly to facilitate manufacturing of, or modification to, an article of footwear. A method of making or modifying an article of footwear includes placing footwear segments on the last assembly by associating an extension portion of at least one footwear segment with the retractable pins, modifying the footwear segments and then removing the extension portion.
Footwear strobel with bladder having grooved flange and method of manufacturing
A strobel for an article of footwear comprises a polymeric bladder that defines an interior cavity. The polymeric bladder is configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around at least a portion of a perimeter of the interior cavity. The peripheral flange defines a groove extending along the peripheral flange. The polymeric bladder may include a first polymeric sheet bonded to a second polymeric sheet at the peripheral flange and joined to the second polymeric sheet at a plurality of interior welds. Methods of manufacturing a strobel and manufacturing footwear are included.
