In a markerless foot size estimation device 100, a shape data input unit 10 acquires three-dimensional shape data of a foot of a subject and stores the three-dimensional shape data in a shape data storage unit 20. A characteristic extraction unit 30 extracts foot shape characteristics from the three-dimensional shape data of a subject's foot stored in the shape data storage unit 20, and stores the foot shape characteristics in a shape characteristic storage unit 40. A machine learning unit 50 uses, as teacher data, foot shape characteristics and arch height stored in the shape characteristic storage unit 40 to create, through machine learning, an estimation model used to estimate arch height based on foot shape characteristics, and stores the estimation model in an estimation model storage unit 60. An estimation output unit 70 uses the estimation model stored in the estimation model storage unit 60 to estimate arch height based on extracted shape characteristics and outputs the arch height.

A shoemaking machine includes a sewing device having a cantilever unit, a work platform and a clamping frame unit. The cantilever unit has a sewing needle extending toward the clamping frame unit. A driving device is disposed on the cantilever unit, and includes a movable seat that is movable toward and away from the clamping frame unit. An ultrasonic positioning device is connected to the cantilever unit, and includes a welding head facing the clamping frame unit. The clamping device is connected to the movable seat and has a clamping space. The ultrasonic positioning device is inserted into the clamping space and is clamped by the clamping device.

Methods and systems are disclosed for three-dimensional printing directly onto an article of apparel. Disclosed is a method and system for direct three-dimensional printing onto an article of apparel, including positioning at least a portion of the article on a tray in a three-dimensional printing system, the portion being positioned substantially flat on the tray, printing a three-dimensional material directly onto the article using a three-dimensional pattern, curing the printed material, and removing the article from the three-dimensional printing system.

The present invention relates to a method for generating control data for controlling a shoe part production machine for making shoes or elements for optimizing traction properties of the shoe by customizing modules to be mounted on the sole for a specific user, said method comprising the steps of: receiving user profile data describing the characteristics of the user where the user profile data comprise use data and test data, receiving a user selection identifying a selected shoe from a number of shoe models or a selected element influencing the property of a shoe, generating modified template data by modifying a shoe sole template corresponding to the selected shoe model or by modifying an element influencing the properties corresponding to the selected element, said modifications being performed based on said received user profile data, generating control data based on said modified template data.

Methods and systems are disclosed for apparel assembly using three-dimensional printing directly onto fabric apparel materials. Disclosed is a method and system for direct three-dimensional printing and assembly of an article of apparel, including designing a three-dimensional pattern for printing, positioning at least a portion of the article on a tray in a three-dimensional printing system, the portion being positioned substantially flat on the tray, printing a three-dimensional material directly onto the article using the designed pattern, curing the printed material, and removing the article from the three-dimensional printing system.

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.

A system for manufacturing shoes is provided that includes two or more pieces of equipment used in the customization and manufacturing of shoes and an alignment fixture that may engage with each piece of equipment by way of an alignment mounting member. The alignment fixture may secure to it a portion of a shoe, such as an upper portion, wherein the shoe portion remains in a flat position, and in a fixed relationship to the alignment fixture, throughout the various processes performed by the pieces of equipment. These processes may include, for example, printing, laser, embroidery, forming, cutting, or the like.
