Abstract

The shoe sole comprises two wooden parts connected together in the ball area by a flexible intermediate part (9) of plastics or the like which is produced from a mould. Only the mould half (1) which takes the blank which is to be worked on its underneath (4) and sleeve surface (5) has a recess (1a) which corresponds to the blank (3) with the other mould half being formed by a flat plate. For each shoe sole the wooden blank (3) is to be finished by cutting a transverse groove (8) into the blank. This groove separates the two wooden parts from each other when the shoe sole is finished. The blank is then placed in the mould and the flexible intermediate part (9) is made together with the outer sole. The blank is then removed from the mould and the finished sole is separated from the rest of the blank material. The excess material is removed from the top of the sole.

Description

" Procédé pour la fabrication de semelles de chaussures
et moule pour l'application de ce procédé."
La présente invention concerne un procédé pour la fabrication de semelles de chaussures, qui se composent de deux parties en bois, qui sont reliées entre elles dans la zone de la protubérance du gros orteil par une pièce intermédiaire flexible en matière synthétique ou analogue, un moule de forme étant utilisé pour la fabrication de cette pièce intermédiaire.
"Process for the manufacture of shoe soles
and mold for the application of this process. "
The present invention relates to a method for manufacturing shoe soles, which consist of two wooden parts, which are interconnected in the area of the protuberance of the big toe by a flexible intermediate piece of synthetic or similar material, a mold. of shape being used for the manufacture of this intermediate piece.

On connait de nombreux types de semelles de chaussures de ce genre qui sont décrits par les brevets ÂT. 352 785, 357 899 et 373 128 ainsi que par le brevet
DE 2 732 391. Toutes ces semelles de chaussures sont fabriquées en réalisant tout d'abord, à l'état fini, les deux parties en bois et les introduisant dans le moule, qui est alors fermé et on termine alors la semelle par injection de la matière synthétique thermoplastique. Il est donc nécessaire d'insérer, pour chaque semelle, deux pièces dans le moule, ce qui est incommode. En outre, on court le risque que les deux pièces se déplacent dans le moule après leur insertion, ce qui conduit à un rebut de l'objet fabriqué. Enfin, les deux moitiés de moule doivent être réalisées avec une grande précision, ce qui rend la fabrication de la semelle très coûteuse.
Many types of shoe soles of this kind are known which are described by the ÂT patents. 352 785, 357 899 and 373 128 as well as by the patent
DE 2 732 391. All these shoe soles are manufactured by first making, in the finished state, the two wooden parts and introducing them into the mold, which is then closed and the sole is then finished by injection of thermoplastic synthetic material. It is therefore necessary to insert, for each sole, two pieces in the mold, which is inconvenient. In addition, there is a risk that the two parts move in the mold after their insertion, which leads to a scrap of the manufactured object. Finally, the two mold halves must be produced with great precision, which makes the manufacture of the sole very expensive.

La présente invention a pour but d'éviter les inconvénients ci-dessus, de simplifier la fabrication de la semelle de chaussure et d'éliminer les rebuts. En outre, la fabrication des semelles doit être rendue moins coûteuse. The object of the present invention is to avoid the above drawbacks, to simplify the manufacture of the shoe sole and to eliminate waste. In addition, the manufacture of soles must be made less expensive.

Conformément à l'invention, ce problème est résolu par un procédé caractérisé en ce que, pour chaque semelle, on façonne une ébauche en bois, sur sa face inférieure ainsi que dans la zone de sa surface enveloppe sensiblement conique en correspondance avec le profil de la semelle de chaussure finie à réaliser, et on entaille par exemple par Iraisage dans l'ébauche, une gorge transversale qui sépare, dans la semelle finie, les deux parties en bois après quoi l'ébauche est placée dans le moule et la pièce intermédiai-e flexible est fabriquée, en conmun, le cas échéant, avec une semelle de marche, après quoi on retire l'ébauche du moule et on sépare la semelle finie du reste de l'ébauche en supprimant la matière en excès subsistant sur la face supérieure de la semelle.  According to the invention, this problem is solved by a process characterized in that, for each sole, a wooden blank is shaped, on its underside as well as in the region of its substantially conical envelope surface in correspondence with the profile of the finished shoe sole to be produced, and for example by notching in the blank, a transverse groove is cut which separates, in the finished sole, the two wooden parts after which the blank is placed in the mold and the intermediate piece. -e flexible is manufactured, in conmun, if necessary, with a walking sole, after which the blank is removed from the mold and the finished sole is separated from the rest of the blank by removing the excess material remaining on the face upper of the sole.

Du fait que les deux parties en bois de la semelle sont reliées rigidement entre elles au cours de la fabrication de la pièce intermédiaire flexible et ne sont séparées l'une de l'autre qu'après le durcissement de la pièce intermédiaire, un déplacement de la position des deux parties en bois au cours de la fabrication de la pièce intermédiaire est exclue. En outre, il n'est plus nécessaire d'insérer qu'une seule pièce dans le moule. Because the two wooden parts of the sole are rigidly connected together during the manufacture of the flexible intermediate piece and are not separated from each other until the intermediate piece has hardened, a displacement of the position of the two wooden parts during the manufacture of the intermediate piece is excluded. In addition, it is no longer necessary to insert a single piece in the mold.

Bien entendu, il serait possible de n'entailler la gorge séparant les deux parties en bois que sur une profondeur correspondant à l'épaisseur de la semelle finie. Of course, it would be possible to cut the groove separating the two wooden parts only to a depth corresponding to the thickness of the finished sole.

Cependant, cela imposerait des tolérances très étroites pour la réalisation de cette profondeur. Pour cette raison, l'invention prévoit que la gorge est entaillée dans l'ébau- che avec une profondeur supérieure à l'épaisseur de la semelle finie. De cette manière, il est possible de réaliser la gorge sur des nachines outils dont la précision n'est pas particulièrement grande. However, this would impose very close tolerances for achieving this depth. For this reason, the invention provides that the groove is notched in the blank with a depth greater than the thickness of the finished sole. In this way, it is possible to make the groove on tool nachines whose precision is not particularly high.

l'invention s'étend, en outre, à un moule destiné à l'application du procédé conforme à l'invention. the invention also extends to a mold intended for the application of the process according to the invention.

Ce moule est caractérisé en ce que, seule la moitié de moule qui reçoit l'ébauche usinée sur-sa face inférieure et sur sa surface enveloppe, est pourvue d'un évidement correspondant à l'ébauche, tandis que l'autre moitié de moule est constituée par une plaque à surface plane. Cette mesure conduit à un abaissement du coût de fabrication.This mold is characterized in that only the half of the mold which receives the preform machined on its underside and on its envelope surface is provided with a recess corresponding to the preform, while the other half of the mold consists of a plate with a flat surface. This measure leads to a lowering of the manufacturing cost.

L'invention est expliquée ci-après avec ré- férence au dessin annexé qui représente une coupe longitudinale schématique d'un moule conforme à l'invention0
La référence 1 désigne la noitié inférieure du moule et la référence 2 désigne sa moitié supérieure.
The invention is explained below with reference to the accompanying drawing which shows a schematic longitudinal section of a mold according to the invention.
Reference 1 designates the lower mold and reference 2 designates its upper half.

Dans un évidement 1a de la moitié inférieure 1, est insérée une ébauche en bois 3. Cette ébauche est façonnée de manière finie sur sa face inférieure 4 et sur sa surface enveloppe 5 en correspondance avec la forme de la semelle à fabriquer.In a recess 1a of the lower half 1, a wooden blank 3 is inserted. This blank is finished shaped on its lower face 4 and on its envelope surface 5 in correspondence with the shape of the sole to be manufactured.

Cette ébauche est pourvue, sur sa face inférieure 4, entre les deux parties en bois 6 et 7 de la semelle finie, d'une gorge 8, qui dépasse la surface limite supérieure 11 de la semelle finie indiquée par une ligne en tirets. Cette gorge sera remplie, par l'intermédiaire de canaux ménagés dans la moitié inférieure 1 du moule, et non représentés dans la figure, d'une matière synthétique thermoplastique ou analogue, qui formera alors la pièce intermédiaire flexible 9 de la senelle.This blank is provided, on its lower face 4, between the two wooden parts 6 and 7 of the finished sole, with a groove 8, which exceeds the upper limit surface 11 of the finished sole indicated by a dashed line. This groove will be filled, via channels made in the lower half 1 of the mold, and not shown in the figure, with a thermoplastic or similar synthetic material, which will then form the flexible intermediate piece 9 of the senelle.

En même temps que cette pièce intermédiaire 9, il est possible de fabriquer également dans le moule, une semelle dite "semelle de marche en injectant de la matiè- re synthétique thermoplastique dans l'espace interrXédiaire compris entre l'ébauche 3 et l'éviderjent la de la moitié inférieure 1 du moule.DU fait que l'ébauche 3 s'apmlique, dans la zone des orteils de la semelle, et égale-.ent dans la zone du talon de celle-ci, contre la paroli de ltévide- ment la, et, en outre, est empêchée par la moitié de moule supérieure 2 contre un déplacement de position vers le haut, on est assuré d'obtertr une épaisseur uniforme de cette semelle de marche 10.
Dès que la pièce intermddiaire 9 et la se aselle de marche 10 ont subi leur durcissement, on retire l'ébauche 3 de la moitié de moule inférieure 1.Ensuite on supprime le matériau de l'ébauche qui se trouve en excès par rapport à la semelle au-dessus de la surface limite 11, en même temps que l'extrémité saillante de la pièce intermédiaire 9, sur une fraiseuse à reproduire.
At the same time as this intermediate piece 9, it is also possible to manufacture in the mold, a sole called a "walking sole" by injecting thermoplastic synthetic material into the intermediate space between the blank 3 and the hollow. of the lower half 1 of the mold. Due to the fact that the blank 3 is applied, in the area of the toes of the sole, and also in the heel area thereof, against the paroli of the shoe. ment, and, moreover, is prevented by the upper mold half 2 against an upward positional movement, it is ensured that a uniform thickness of this tread 10 is obtained.
As soon as the intermediate piece 9 and the running saddle 10 have undergone their hardening, the blank 3 is removed from the lower half of the mold 1. Then the material of the blank which is in excess with respect to the material is removed. sole above the limit surface 11, at the same time as the projecting end of the intermediate piece 9, on a milling machine to be reproduced.

Il est cependant également possible de rogner une partie du matériau en excès au moyen d'une scie et de ne fraiser que la partie restante ainsi que la surface d'appui du pied, c'est-à-dire la surface limite 11, au moyen d'une fraiseuse à reproduire de finition. It is however also possible to trim a part of the excess material by means of a saw and to mill only the remaining part as well as the bearing surface of the foot, that is to say the limit surface 11, at the by means of a finishing reproducing milling machine.

L'invention n'est pas limitée à l'exemple décrit et représenté et diverses modifications restent possibles sans sortir du domaine de l'invention. Par exemple, la matière synthétique utilisée ne doit pas obligatoire- ment être injectée dans le moule à travers des canaux. Il est possible de la mettre en place dans le moule, sous la formede deux composants, avant l'insertion de l'ébauche et de réaliser ensuite son expansion en mousse.  The invention is not limited to the example described and shown and various modifications remain possible without departing from the scope of the invention. For example, the synthetic material used does not necessarily have to be injected into the mold through channels. It is possible to place it in the mold, in the form of two components, before inserting the blank and then to carry out its foam expansion.
