Description

SISTEMA DE PROTECCIÓN DE LA COSTURA DE COSIDO DE UN SEWING SEWING PROTECTION SYSTEM OF A
CORTE DE CALZADO FOOTWEAR CUT
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un sistema de protección de la costura del corte de un calzado, en donde dicha costura realiza la fijación mediante cosido del borde proyectado hacia fuera del corte con el piso o la entresuela del propio calzado, conocido el proceso como "Stich Down". The present invention relates to a system of protection of the seam of the cut of a shoe, wherein said seam makes the fixation by sewing the projected edge out of the cut with the floor or the midsole of the footwear itself, known as the process as " Stich Down. "
El objeto de la invención es conseguir la impermeabilización de la costura anteriormente referida y por lo tanto del calzado constituido mediante el citado sistema "Stich Down". The object of the invention is to achieve the waterproofing of the aforementioned seam and therefore of the footwear constituted by said "Stich Down" system.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Existen procesos distintos de fabricación de calzado, pudiéndose citar como mas conocidos los denominados "Strobel" y el "Stich Down", de manera que en el primer caso se crea una funda interior del corte, mediante cosido en zig-zag de una palmilla al corte, mientras que en el segundo caso lo que se hace es fijar una palmilla a la plantilla y posteriormente tensar el corte y pegar éste al piso, quedando la costura de fijación de la palmilla hacia el exterior del calzado y por lo tanto con una total falta de impermeabilidad en el mismo. Ese problema se intenta resolver mediante un pegado hacia el exterior del reborde perimetral del piso al corte, lo que no evita el tener que fijar o coser la palmilla constitutiva de la funda y la de la etapa de pegar el piso a la propia palmilla. There are different shoe manufacturing processes, the so-called "Strobel" and the "Stich Down" being better known, so that in the first case an inner sheath of the cut is created, by zigzag sewing of a palm to cut, while in the second case what is done is to fix a palm to the template and then tension the cut and stick it to the floor, leaving the seam fixing the palm to the outside of the footwear and therefore with a total lack of impermeability in it. This problem is attempted to be solved by sticking the perimeter edge of the floor to the cut to the outside, which does not prevent having to fix or sew the constituent palm of the sheath and that of the stage of gluing the floor to the palm itself.
En cualquier caso, la impermeabilización no se consigue con eficacia y no se puede evitar la utilización de la palmilla de montado, y sin embargo se requieren adhesivos para fijar el corte al piso. In any case, the waterproofing is not achieved effectively and the use of the mounting palm cannot be avoided, and however adhesives are required to fix the cut to the floor.
Por otro lado, en la Patente de Invención 414080 se describe un proceso de fabricación de un calzado, y concretamente un proceso de fijación del corte al piso, mediante costura, pero siempre con una falta de impermeabilización de la fijación. On the other hand, in the Invention Patent 414080 a process of manufacturing a shoe is described, and specifically a process of fixing the cut to the floor, by sewing, but always with a lack of waterproofing of the fixation.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El sistema que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, en base a una solución sencilla pero enormemente eficaz. The system that has been recommended has been conceived to solve the problem described above, based on a simple but enormously effective solution.
Concretamente, el sistema novedoso consiste en proteger la costura resultante del proceso "Stich Down" mediante el sellado con una tira de goma cruda, siendo el conjunto posteriormente vulcanizado en un autoclave, de forma tal que la costura referida queda protegida contra el agua y por tanto impermeabilizado el calzado, además de constituir un medio que refuerza la unión entre corte y piso, ya que la costura que une el corte al piso o entresuela está realizada sobre un reborde proyectado hacia el exterior del propio corte. Mediante este sistema no se requiere la utilización de palmillas de montado, reduciéndose el empleo de adhesivos puesto que la unión del corte al piso se realiza por costura y no mediante pegado, dando lugar en definitiva y como resultado a un calzado de gran flexibilidad. Specifically, the novel system consists in protecting the seam resulting from the "Stich Down" process by sealing it with a strip of raw rubber, the assembly being subsequently vulcanized in an autoclave, so that the seam referred to is protected against water and both waterproofed the footwear, in addition to constituting a means that reinforces the union between cut and floor, since the seam that joins the cut to the floor or midsole is made on a projected edge to the outside of the cut itself. This system does not require the use of mounting palms, reducing the use of adhesives since the union of the cut to the floor is done by sewing and not by gluing, resulting in definitive and as a result to a shoe of great flexibility.
Mediante este sistema de protección se consigue además un óptimo acabado en lo que respecta al aspecto estético del calzado, independientemente de que además de la impermeabilización que se consigue con la tira de goma, se consigue reforzar la unión entre corte y piso. This protection system also achieves an optimal finish in regards to the aesthetic aspect of the footwear, regardless of the fact that in addition to the waterproofing that is achieved with the rubber strip, the joint between cut and floor is reinforced.
DESCRIPCIÓN DE LOS DIBUJOS DESCRIPTION OF THE DRAWINGS
Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente: To complement the description that will then be made and in order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
La figura 1.- Muestra un detalle en perspectiva de una parte lateral y parcial de un calzado en el que se muestra la correspondiente costura de unión del corte al piso, todo ello como queda convencionalmente. Figure 1.- Shows a detail in perspective of a side and partial part of a shoe in which the corresponding seam of union of the cut to the floor is shown, all as it is conventionally.
La figura 2.- Muestra una vista en perspectiva del calzado dotado de la tira de goma de cubrición e impermeabilización de la costura mostrada en la figura anterior. REALIZACIÓN PREFERENTE DE LA INVENCIÓN Figure 2.- Shows a perspective view of the footwear provided with the rubber covering and waterproofing strip of the seam shown in the previous figure. PREFERRED EMBODIMENT OF THE INVENTION
Como se puede ver en las figuras referidas, el proceso "Stich Down" de fabricación de calzados, consiste en que el borde del corte (1) del calzado se monta hacia fuera y se cose, mediante una costura (2) al correspondiente piso (3) o entresuela, como se representa en la figura 1. As can be seen in the aforementioned figures, the "Stich Down" process of footwear manufacturing consists in that the edge of the cut (1) of the footwear is mounted outwards and sewn, by means of a seam (2) to the corresponding floor ( 3) or midsole, as shown in figure 1.
Pues bien, la novedad consiste en proteger dicha costura (2) mediante una tira de goma cruda (4) que es posteriormente vulcanizada con el resto del calzado en un autoclave, proporcionando de esta manera no solamente la protección e impermeabilización de la costura (2) del calzado, y por tanto de éste último, sino que la unión entre corte (1) y piso o entresuela (3) queda reforzado, no solamente contra el agua sino contra otros agentes externos, como pueden ser roces, etc. Well, the novelty consists in protecting said seam (2) by means of a strip of raw rubber (4) that is subsequently vulcanized with the rest of the footwear in an autoclave, thus providing not only the protection and waterproofing of the seam (2 ) of footwear, and therefore of the latter, but the union between cut (1) and floor or midsole (3) is reinforced, not only against water but against other external agents, such as friction, etc.
El calzado con la mejora descrita y correspondiente a la invención, no requiere palmilla de montado, además de verse reducido el empleo de adhesivos puesto que la fijación del corte al piso se realiza mediante costura y no mediante pegado, resultando además un calzado notablemente flexible. The footwear with the improvement described and corresponding to the invention, does not require mounting palm, in addition to reducing the use of adhesives since the fixation of the cut to the floor is done by sewing and not by gluing, resulting in a remarkably flexible footwear.
