Abstract

The present patent application describes a string guide module for adjustment of the shank, which makes it possible to do away completely with the use of fastening members, thus considerably improving the quality and comfort of footwear, and also saving raw materials and improving productivity. The aim of the invention is to allow longitudinal, latitudinal and angular adjustment of the pulling vector of the strings, particularly longitudinal positional adjustment along the last (F), while having modular characteristics.

Abstract

The present patent application relates to an "X" stitching method, designed in particular for the mounting of uppers by means of the string-lasting system, which pertains especially to the footwear sector. The invention includes application to an upper (1), for integral assembly of footwear, using string lasting (2) as element responsible for closing the edges of this upper (1) against the last (3); with overlock-type stitching, used here as an exemplary embodiment, of at least one "X" (X) in an upper (1), for integral assembly of footwear, using string lasting (12) as element responsible for closing the edges of this upper against a last (F). The "X" (X) stitching method makes it possible to assemble all models of footwear and all heights of known heels; after assembly, the sole may be poured or injected directly.

Abstract

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.

Abstract

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 - sewing of the edges with a lasting string. The invention even includes the use of this technology in footwear models which are normally excluded because they have sturdy, not very flexible shoe uppers which are difficult to conform using string lasting. For that purpose, it is sufficient to provide a shoe upper with new dimensions suitable for this mounting technology, whenever necessary. The machine is capable of lasting any string and to adjust any shoe upper to the form, provided these materials conform with acceptable quality standards for footwear components. The invention is characterised 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; these modules can be associated, that is to say, module (3) together with module (4), or module (3) together with module (4) together with module (5), or be used separately or in various combinations of at least one of these modules, modules (3) and (4) optionally comprising force and speed actuators.
