    [0001] TECHNICAL FIELD The present invention relates to a molding element for molding a cut in a tread of a tire. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention also relates to a set of molding elements forming a network of molding elements in a mold.
    [0002] STATE OF THE ART Document FR2939712 discloses a set of molding elements forming a network. The molding elements, here cords or strips, are made in one piece by laser sintering. These molding elements make it possible to mold cutouts in a tread of a tire. The network formed by the molding elements can have a large size. Under certain conditions of manufacture, this network can be subjected to significant deformations, which makes acceptable manufacturing. network, it is necessary adequate laser and more out of the tolerances of In addition, to manufacture such a to provide a sintering machine a tray which increases particularly the reception of the large network. This manufacturing costs. In addition, when a molding element of the network is non-compliant, the entire network must be discarded. There is therefore a need to find a solution to obtain a set of molding elements of good mechanical strength, respecting manufacturing tolerances and which is simple and convenient to manufacture.
    [0003] DEFINITIONS "Pneumatic" means all types of elastic bandages subjected to internal pressure or not. By "tread" of a tire is meant a quantity of rubber material delimited by side surfaces and by two major surfaces, one of which is intended to come into contact with a road surface when the tire is rolling and the other other is oriented towards the inside of the tire. By "cut in a tread" is meant either a fine cut also called incision, or a wide cut also called groove. By "molding element" is meant an element disposed in a mold adapted to make cuts in the tread of a tire. A molding element capable of making an incision in the tread is called a coverslip. A molding element adapted to make a groove in the tread is called a bead. SUMMARY OF THE INVENTION The invention relates to a molding element for molding a cut in a tread of a tire. The molding element has an assembly means, which assembly means is capable of bonding this molding element to another molding element to form a set of molding elements. This set of molding elements is intended to be reported in a mold. The interweaving between the molding elements makes it possible to guarantee their good mechanical strength during cooking of the tire. In addition, the set of molding elements comprising different molding elements thus nested is more robust. In addition, the various molding elements can always be made by laser sintering, which makes it possible to obtain highly complex forms of molding elements. It will be noted that the set of molding elements comprising the elements assembled together can be directly fixed in a mold, for example by gluing. Alternatively, the molding elements of the set of molding elements may be "embedded" together in aluminum, prior to the establishment of the set of molding elements in the mold.
    [0004] In a preferred embodiment, the molding element comprises a side wall. This molding element having a receiving slot of the other molding element in this side wall. This mode of connection is simple and practical to achieve. In an alternative embodiment, the receiving slot is disposed in a protruding portion from the side wall of the molding element. The protrusion portion improves the connection between the two molding elements. In another alternative embodiment, the receiving slot is inclined with respect to the side wall of the molding element. The inclination of the slot makes it possible to provide an inclination between two nested molding elements. In another alternative embodiment, the molding element 30 has a transverse wall generally perpendicular to the side wall of this molding element. The molding element comprises a stud and / or a hollow on this transverse wall.
    [0005] The stud and / or the hollow allows (tent) to structure a set of molding elements that can be adapted to the size of the mold. In addition, this provides a more complex set of molding elements.
    [0006] In another variant embodiment, the molding element is a bead. In another variant embodiment, the molding element is a lamella. In another variant embodiment, the lamella has an extra thickness and the assembly means are arranged in this extra thickness.
    [0007] This makes it possible to make the assembly between the molding elements more robust. Another object of the invention concerns a set of molding elements intended to be attached to a mold, this set of elements comprising an assembly of a plurality of elements. tight. Each molding element is able to mold a cut in a tread of a tire. Each molding element comprises an assembly means, the assembly means being able to bind this molding element with another molding element to form a part of the set of molding elements. In a preferred embodiment, all or part of the molding elements of the assembly are slats of the "water drop" type each having at one end an extra thickness. This extra thickness comprises an assembly means. The set of elements comprises an assembly of at least two strips of "water drop" type.
    [0008] A complex and robust network of molding elements is thus obtained. BRIEF DESCRIPTION OF THE DRAWINGS Other characteristics and advantages of the invention will emerge from the following description, given by way of example, without limitation, with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a molding element according to the invention, - Figure 2 is a side view of the molding element of Fig.1, according to a second embodiment of the invention; - Figure 3 is a perspective view of a set of molding elements according to the invention, Figure 4 is a perspective view of a set of molding elements according to a second embodiment of the invention.
    [0009] In the following description, substantially identical or similar elements will be designated by identical references. Fig. 1 has a molding element 1 for molding a cut in a tread of a tire. This molding element 1 has the form here of a "water droplet" type plate with an extra thickness 15 at one of its ends. This molding element 1 also comprises a second thickening 16, less wide than the first thickening, at its base. The first oversize 15 and the second oversize 16 receive here receiving slots 3, 7 to receive another molding element. More particularly, the receiving slot 7 associated with the second thickening 16 extends in a portion 5 protruding from a side wall 9 of the molding element 1. The two receiving slots 3 and 7 are aligned.
    [0010] The molding element 1 also comprises a recess 13 on a side wall 11. This recess 13 is intended to receive a stud of another molding element for assembling the two molding elements.
    [0011] Fig.2 shows an alternative embodiment, wherein the slot 3 is inclined at an angle with respect to a vertical direction Z. This angle a is between 5 ° and 45 °. It is also possible that the slot 3 is inclined relative to a normal direction to the side wall 9 of the molding element 1. This inclination can be between, for example between 5 ° and 75 °. In this case the receiving slot 7 of the protruding part 5 will also be inclined at the same inclination and aligned with the slot 3, but the protruding part 5 will be offset with respect to the slot 3. It will be noted that the width L of the slot 3 may be slightly greater than the thickness of the molding element which will be housed in this slot 3, so as to allow a set of assembling between the two molding elements.
    [0012] FIG. 3 represents the molding element 1 of FIG. 1 assembled in a set of molding elements 17. More particularly, the set of molding elements 17 here comprises several molding elements 1, 19, 21, 25, 27 , each molding element being able to mold a cutout in the tread of a tire. Fig. 4 represents a set of more complex molding elements comprising a plurality of blades of the "water drop" type 35, 37, 39, each having at one of their end an extra thickness 41. This extra thickness 41 is adapted to receive the means assembly of the slats type "drop of water".
    [0013] The invention is not limited to the examples described and shown and various modifications can be made without departing from its scope. Thus, in an alternative embodiment, the molding element 1 of Fig.1 is a bead. The molding elements are manufactured by laser sintering. Alternatively, these molding elements are manufactured by any other manufacturing process, such as foundry, machining, etc ....
    [0014] Fig. 1 shows slots located on enlarged parts of the molding element. Alternatively, a slot may extend over a large height of this molding element. This is particularly interesting when the molding element does not have enlarged parts but is thick enough to support the assembly means in its height.
