Abstract:
In certain aspects, the inventive subject matter is directed to production of constructs of footwear and components thereof by jet extrusion. The inventive subject matter contemplates novel processes for making such constructs using jets or streams of materials that solidify as fibers, and which form into two- or three-dimensional webs as they are collected. The webs may be in the nature of films, membranes, or mats. In some embodiments, the inventive subject matter generally relates to nonwoven textiles consisting of webs of superfine fibers, i.e., fibers with diameters in nanoscale or micronscale ranges.
Abstract:
Laser siping forms sipes in an article. The laser operates in a scan laser configuration for some sipe patterns and the laser operates in a fixed laser concept for other siping patterns. The article on which the sipes are formed is secured by a part holder. Movement of the part holder may be computer controlled. Movement of the laser may also be computer controlled. A movement of a reflective surface of the laser may be computer controlled. Together, the movement of the part holder, the laser, and the reflective surface is coordinated to achieve the scan laser configuration and the fixed laser configuration when forming sipes.
Abstract:
The invention relates to a method for the mass production of shoe inserts with different thicknesses by compression cutting, said method comprising the steps of: i) using a mobile table carrying a gauge including more than one cavity having a particular shape; ii) securing the gauge on the mobile table using fastening devices; iii) placing the elastic material to be cut on the gauge; iv) compressing the elastic material into the cavities formed in the gauge by moving the table with the gauge and the elastic material under a fixed, inclined compression conveyor belt; cutting the elastic material with a belt knife; characterised in that said method further comprises the step of adjusting the horizontal alignment of the gauge on the mobile table using adjustment devices.
Abstract:
Procédé de production en grande série de pièces rapportées de chaussure, d'épaisseurs différentes, par coupe par compression, ledit procédé comprenant les étapes consistant à: i) utiliser une table mobile qui supporte un gabarit comprenant plus d'une cavité de forme particulière; ii) fixer le gabarit sur la table mobile avec des dispositifs de fixation; iii) placer le matériau élastique destiné à être coupé sur le gabarit; iv) comprimer ledit matériau élastique dans les cavités du gabarit formées en déplaçant la table avec le gabarit et le matériau élastique sous un tapis roulant de compression incliné fixe; v) couper le matériau élastique avec un couteau ruban /caractérisé en ce que ledit procédé comprend en outre l'étape consistant à régler l'alignement horizontal du gabarit sur la table mobile avec des dispositifs de réglage.
