METHOD OF FORMING THREE-DIMENSIONAL COMPOSITE
A method of forming three-dimensional composite comprising steps of: (a) manufacturing at least one shaping member; (b) fitting each of the at least one shaping member on each of at least one mold; (c) adhering at least one connection sheet on said each shaping member so as to form each of at least one semi-finished product; (d) fixing said each semi-finished product in a cavity; and (e) heating said each semi-finished product and vacuuming the cavity. Said shaping member has at least one orifice and covers said each mold, and each connection sheet has a substrate and an adhesive layer, a melting point of the adhesive layer is less than the substrate. Said each semi-finished product in the cavity is heated until the adhesive layer melts, and the cavity is vacuumed so that the adhesive layer penetrates into said each shaping member, thus producing a three-dimensional finished product.
VAMP 3D-PRINTING SYSTEM
Disclosed is a vamp 3D-printing system. Mainly, by using a 3D-printing device comprising at least one fixed printing head and a rotatable printing head, printable materials are overlapped and printed on a vamp assembly by means of cooperation of the fixed printing head and the rotatable printing head according to a preset printing program of a computer. In this way, the technical effects are achieved that vamp pattern styles having thick and thin line changes and high precision of printing positions are printed by using more two printing heads; in addition, manufacturing costs are actually reduced and manufacturing procedures are actually simplified by applying the 3D-printing technology to printing of vamp pattern styles.
Shoe upper manufacturing method
A shoe upper manufacturing method is provided. The shoe upper manufacturing method includes the steps of obtaining materials for shoe uppers, forming the shoe uppers, processing the shoe uppers, and printing the shoe uppers carried out in turn. Thus a multi-layer composite footwear fabric is produced and further processed to form shoe uppers required. Thereby different heating temperature and time are set for heat melting and adhesion of thermoplastic elastomer onto footwear fabric made from different materials in order to meet different requirements of users. Moreover, production efficiency is improved and production capacity is increased by combination of one upper mold with a plurality of lower molds. The present method is more efficient than those in current use.
Methods of Vacuum Forming Articles of Wear
Described are methods of two-dimensionally and three-dimensionally forming an article of wear using vacuum forming in an automated process. In the two-dimensional method, the article of wear comprises a generally flat shape with three-dimensional features molded into the first material layer.
POLYURETHANE INJECTED BOOT ASSEMBLY AND ASSOCIATED MANUFACTURING METHOD
A footwear assembly having an upper that comprises a neoprene sock with a foot portion integrally connected to a leg portion. The foot portion has heel, vamp and under-foot portions. The leg portion has front shin, side wall, and rear calf-side portions. The upper has a unitary, outer, injection molded layer molded directly onto the foot and shin portions of the neoprene sock, while the sidewall and rear calf-side portions remain substantially uncovered by the injection molded layer. The injection molded layer encases the foot portion of the neoprene sock. The injection molded layer on the shin portion defines a shin guard portion having a necked down area integrally connected to the injection molded layer at the vamp portion, wherein the shin guard extends upwardly from the necked-down portion in an outwardly diverging shape away from the vamp.
LAST SYSTEM FOR ARTICLES WITH BRAIDED COMPONENTS
A last system and a method of making the last system are disclosed. The last system includes a last member and an exterior layer. The exterior layer becomes deformable when heated above a characteristic temperature. The method can include forming a braided footwear component on the last system. The exterior layer may be joined with the braided footwear component by heating the last system above the characteristic temperature.
Article of Footwear Having an Upper with a Matrix Layer
Articles of footwear, including athletic footwear, include one or more of: (a) a sole structure; (b) an upper having lateral and medial side elements engaged with the sole structure, the upper made from a polymer matrix structure that extends through at least a heel region; (c) a size adjustment mechanism located at the heel region; (d) a heel tongue element located adjacent the size adjustment mechanism; (e) a shoe securing mechanism; (f) an instep tongue member; and/or (g) a bootie member located at least partially within the foot-receiving chamber. Methods of manufacturing such articles of footwear also are disclosed.

Methods of manufacturing such articles of footwear also are disclosed.
TWO-DIMENSIONAL SHOE MANUFACTURING
Described are methods for the manufacture of a plurality of shoes, an apparatus to perform such method, as well as shoes manufactured by such method. According to certain examples, the method for the manufacture of a plurality of shoes includes providing a plurality of first shoe components for the manufacture of the plurality of shoes, and moving the plurality of first shoe components with a transport means which is at least partially comprised of the plurality of first shoe components.
SKATE AND METHOD OF MANUFACTURE
A skate boot shell including a tridimensional outer sub-shell made of a first material, the outer sub-shell including a first sole portion connected to first heel, ankle and side portions; a tridimensional inner sub-shell received within and connected to the outer sub-shell, an outer surface of the inner sub-shell being complementary to an inner surface of the outer sub-shell, the inner sub-shell being made of a second material different from the first material; and a tridimensional reinforcement sub-shell made of a third material different from the first and second materials and bonded inside at least one of the inner and outer sub-shells.
