/ 78 METHOD FOR ARRANGING ELONGATED ELEMENTS TO BE USED IN A PROCESS FOR CONSTRUCTING TIRES FOR VEHICLE WHEELS, AND PROCESS AND INSTALLATION FOR CONSTRUCTING TIRES FOR VEHICLE WHEELS DESCRIPTION

[001] The present invention relates to a process and an installation for constructing vehicle wheel tires and a method for arranging elongated elements to be used in said process.

[002] A tire for vehicle wheels generally comprises a carcass structure, a crown structure arranged in a radially external position relative to the carcass structure, and a pair of sidewalls representing the axially external surfaces of the tire, relative to a median plane perpendicular to the geometric axis of rotation of said tire.

[003] The carcass structure comprises at least one carcass ply formed from reinforcing cords embedded in a matrix of elastomeric material. The carcass ply has flaps at opposite ends respectively engaged to annular anchoring structures. The latter are disposed in the areas of the tire generally identified by the name “beads” and are each normally formed by a substantially circumferential annular insert called a “bead core” to which at least one filling insert is applied, in the radially outward position, which narrows radially away from the geometric axis of rotation.

[004] Specific reinforcement structures can be provided in the beads with the function of improving torque transmission to the tire.

[005] In the case of “tubeless” tires, that is, without an inner tube, a layer of elastomeric material, generally known as a “liner”, may also be provided in the radially inner position relative to the carcass structure to provide the necessary impermeability to the tire's inflation air. Generally, the liner extends from one bead to the other. Petition 870230053695, dated 06 / 22 / 2023, p. 12 / 114 / 78

[006] The crown structure comprises a belt structure and, in the radially external position relative to the belt structure, a tread produced from elastomeric material.

[007] The belt structure comprises one or more layers of belt arranged radially juxtaposed to one another, having textile or metallic reinforcing cords that have an orientation substantially parallel to the circumferential extension direction of the tire (zero degree layer) and / or that have a cross orientation.

[008] Between the carcass structure and the belt structure, it is possible to provide a layer of elastomeric material, called a “belt”, which has the function of making the radially external surface of the carcass structure as uniform as possible for subsequent application of the belt structure.

[009] Longitudinal and transverse grooves are normally formed in the tread, arranged to define a desired tread pattern. Between the tread and the belt structure, it is possible to place a so-called “sublayer” produced from elastomeric material with properties suitable for obtaining a stable bond between the belt structure and the tread itself.

[0010] The sidewalls are produced from elastomeric material and represent the axially external surfaces in relation to the annular anchoring structures, the carcass ply(ies), the belt layer(s) and possibly at least a portion of the tread. For example, each of the sidewalls extends from one of the lateral edges of the tread to the respective annular anchoring structure for the beads.

[0011] Sidewalls are intended to protect the carcass structure from atmospheric agents and lateral impacts (e.g., against curbs). In self-supporting tires, suitable sidewall inserts are designed to provide the tire with sufficient strength to adequately support the vehicle load when the tire is used in a deflated state and to provide Petition 870230053695, dated 06 / 22 / 2023, page 13 / 114 / 78 favorable comfort properties when, on the other hand, the tire is in normally inflated operating conditions. A sidewall insert produced from elastomeric material is preferably positioned axially externally in relation to the lining and axially internally in relation to each sidewall to define a suitable structure to adequately support the tire in the deflated state, preventing the sidewall from sagging or bulging on itself, without compromising normal driving conditions.

[0012] The term “elastomeric material” is intended to indicate a composition comprising at least one elastomeric polymer and at least one reinforcing filler. Preferably, such a composition also comprises additives such as, for example, a crosslinking agent and / or a plasticizer. Thanks to the presence of the crosslinking agent, such material can be crosslinked by heating, in order to form the final product.

[0013] The term "elongated element" is intended to indicate an element produced from elastomeric material that has predominant extension along a longitudinal direction. Such an elongated element preferably consists only of elastomeric material.

[0014] The term “base surface” of the elongated element is intended to indicate the radially inner surface of each coil of the elongated element when it is wound onto a storage reel. This base surface corresponds to the lower surface of the elongated element once unwound from the storage reel and placed in a substantially horizontal plane.

[0015] The term "elongated elements that are identical to each other" is intended to indicate elongated elements that have the same composition and geometry. Two elongated elements that are identical to each other consist of the same elastomeric material and have the same shape along a cross-section perpendicular to the longitudinal direction of the main extension and Petition 870230053695, dated 06 / 22 / 2023, p. 14 / 114 / 78 have the same dimensions along such a cross-section. Two elongated elements that are identical to each other also have the same elongation in the longitudinal direction, or in any case such that the elongation of a first elongated element is between 99% and 101% of the elongation of a second elongated element when subjected to the same load in the longitudinal direction.

[0016] The term "elongated elements that are different from each other" is intended to indicate elongated elements that have different composition and / or geometry, in which, in combination or alternatively, the elastomeric materials are different in composition, the respective shapes along a cross-section perpendicular to the longitudinal direction of the main extension are different from each other, such sections have different dimensions.Two elongated elements that are different from each other may also have the same elongation in the longitudinal direction, or in any case such that the elongation of a first elongated element is between 99% and 101% of the elongation of a second elongated element when subjected to the same load in the longitudinal direction, or they may have different elongations in the longitudinal direction such that the elongation of a first elongated element is less than 99% or greater than 101% of the elongation of a second elongated element, when subjected to the same load in the longitudinal direction.

[0017] The term “structural component” of a tire is intended to indicate any portion of the tire capable of performing its function or a part thereof. Examples of structural components of the tire are the following: the carcass structure, the crown structure, or parts thereof, such as the liner, downline, anti-abrasion inserts, bead core, internal filler inserts in the bead area (and therefore the annular anchoring structures defined by bead cores and their respective internal filler inserts), carcass ply(ies), belt layer(s), belt sublayer, sublayer Petition 870230053695, dated 06 / 22 / 2023, page 15 / 114 / 78 of the tread, sidewalls, sidewall inserts, tread, textile or metallic reinforcements, reinforcement elements produced from elastomeric material, etc., or a part thereof.

[0018] The term “service fabric” or “service component” is intended to indicate a fabric associated with an elongated element arranged to prevent the coils of the elongated element wound onto a winding support from sticking to one another. Preferably, said service fabric is also configured to provide the elongated element with a desired structural consistency when it is wound onto a winding support.

[0019] The term "self-supporting tire" is intended to indicate a tire that differs from a standard tire in that it is able to support the vehicle's load under a considerable or total loss of pressure, for example when there is a puncture, allowing the driver to travel a certain distance to reach a mechanic's shop without having to stop to change the tire in a potentially dangerous situation.

[0020] The term “parallel winding” of two elongated elements is intended to indicate a simultaneous winding of a pair of elongated elements on one or more winding supports.

[0021] The term “winding diameter” of an elongated element on a storage reel or winding support is intended to indicate the distance between the geometric axis of rotation of the storage reel or winding support and the point of the elongated element still wound on the storage reel or winding support and radially furthest from said geometric axis of rotation.

[0022] The terms axial, axially, radial, radially, “circumferential” and “circumferentially” are used in reference to the winding supports used in the tire construction process.

[0023] In particular, the terms “axial” and “axially” mean Petition 870230053695, dated 06 / 22 / 2023, p. 16 / 114 / 78 references / sizes arranged / measured or extending in a direction substantially parallel to a geometric axis of rotation of the winding supports.

[0024] The terms “radial” and “radially” mean references / sizes arranged / measured or extending in a direction substantially perpendicular to a geometric axis of rotation of the winding supports and resting in a plane comprising such geometric axis of rotation.

[0025] The terms “radially inside / outside” are intended to indicate respectively a position closer to or further from said geometric axis of rotation of the winding supports.

[0026] The terms “axially internal / external” are intended to indicate, respectively, a position closer to or further from a median plane perpendicular to the geometric axis of rotation of the winding supports.

[0027] The terms “circumferential” and “circumferentially” mean references / sizes arranged / measured or extending along a circumference that extends around the geometric axis of rotation of the winding supports.

[0028] A vehicle wheel tire comprises a plurality of structural components produced from elastomeric material. Non-limiting examples of these include: the tread, the sidewalls, the sidewall inserts, the so-called subply and / or belt, the liner, the annular reinforcement inserts and others.

[0029] In the production processes of tires for vehicle wheels, at least some of these structural components are produced from elongated elements that are wound, in a construction line, onto a forming drum.

[0030] In the Applicant's experience, at least for some types Petition 870230053695, dated 06 / 22 / 2023, p. 17 / 114 / 78 of tires, there is simultaneous deposition on the forming drum of two elongated elements that are identical to each other. An example of such elongated elements deposited simultaneously on the forming drum is a pair of elongated elements that, during the construction of a self-supporting tire, are deposited axially separately on the forming drum, before or after the deposition of one or more carcass plies, to produce a respective pair of sidewall inserts of the self-supporting tire.

[0031] The Applicant noted that, in order to simultaneously deposit two elongated elements that are identical to each other onto a forming drum, a process is currently provided in which two elongated elements of the same elastomeric material are simultaneously extracted from a single extrusion device.

[0032] As the elongated elements progressively exit the extrusion device, they are deposited onto a storage reel positioned in the extrusion line substantially downstream of the extrusion device. The deposition of the elongated elements is carried out by winding the elongated elements onto coils on the storage reel, simultaneously producing two pluralities of coils axially adjacent to each other and separated on the storage reel. During winding onto the storage reel, the base surfaces of the elongated elements are coupled to a service fabric that prevents direct contact between the coils of the same elongated element, preventing them from adhering to each other. The service fabric is unwound from a service reel during coupling to the elongated elements.

[0033] The storage reel with both elongated elements that are identical to each other wound up is then moved and housed in a storage container and, when needed, it is removed from storage and placed on a construction line near the drum of Petition 870230053695, dated 06 / 22 / 2023, page 18 / 114 / 78 conformity.

[0034] On the construction line, both elongated elements that are identical to each other are simultaneously unwound from the storage reel and simultaneously deposited onto the forming drum to simultaneously produce the desired pair of structural components made from elastomeric material. During the unwinding of the elongated elements, the service fabric is separated from the base surface of the elongated elements and wound onto a service reel.

[0035] The Applicant addressed the problem of tire construction where the two elongated elements simultaneously deposited on the forming drum are different from each other. Such a requirement could, for example, be necessary, in the Applicant's experience, during the construction of a self-supporting tire where the sidewall insert on one side of the tire is different from the sidewall insert on the other side of the tire.

[0036] The Applicant noted that it would not be possible to simultaneously deposit two elongated elements that are different from each other in the forming drum using the process described above, since each storage reel comprises two elongated elements that are identical to each other.

[0037] The Applicant realized, however, the need to simultaneously deposit two elongated elements that are different from each other into the forming drum without having to redesign or modify the extrusion line and / or the construction line.

[0038] The Applicant realized, in fact, that this would allow the use of pre-existing production facilities, avoiding the costs of a new project, prototyping and production of new extrusion lines and new construction lines. This would also avoid providing new production spaces to house new production facilities in addition to those already existing. Petition 870230053695, dated 06 / 22 / 2023, page 19 / 114 / 78

[0039] The Applicant noted that, in order to use the same pre-existing extrusion lines, the construction lines must be fitted with storage reels already configured to simultaneously deposit two elongated elements that are different from each other onto the forming drum.

[0040] The Applicant noted, however, that in order to use the same pre-existing extrusion lines, each extruder device must continue both to simultaneously extrude the respective elongated elements that are identical to each other and to wind in parallel each pair of extruded elongated elements onto a respective storage reel.

[0041] The Applicant realized that it would be possible to provide, between the extrusion line and storage or between storage and the construction line, a movement of at least some of the elongated elements wound on the storage reels, so as to alter the arrangement of the elongated elements on the storage reels that exit the extrusion line in relation to this on the storage reels that enter the construction line.

[0042] The Applicant realized that, in order for such a change in the arrangement of the elongated elements on the storage reels not to result in any alteration to the operations performed on the extrusion line and the construction line, it would be necessary to:

[0043] - starting from a first pair of elongated elements that are identical to each other, extruded simultaneously by an extruder device and wound onto a first initial reel and from a second pair of elongated elements that are identical to each other but different from the elongated elements of the first pair of elongated elements, extruded simultaneously by the extruder device and wound onto a second initial reel;

[0044] - end with a first pair of elongated elements that Petition 870230053695, dated 06 / 22 / 2023, page 20 / 114 / 78 are different from each other wound onto a first end reel and with a second pair of elongated elements that are different from each other wound onto a second end reel.

[0045] The present invention therefore relates, in a first aspect thereof, to a method for arranging elongated elements to be used in a process for constructing tires for vehicle wheels.

[0046] Preferably, parallel winding is provided of a first elongated element and a second elongated element of a first type on a first initial winding support.

[0047] Preferably, the elongated elements of the first type are identical to each other.

[0048] Preferably, parallel winding of a third and a fourth elongated element of a second type is provided on a second initial winding support.

[0049] Preferably, the elongated elements of the second type are identical to each other.

[0050] Preferably, the elongated elements of the second type are different from the elongated elements of the first type.

[0051] Preferably, the unwinding of the first elongated element of the first initial winding support is provided.

[0052] Preferably, the winding of the first elongated element is provided on a first end winding support.

[0053] Preferably, the unwinding of the second elongated element of the first initial winding support is provided.

[0054] Preferably, the winding of the second elongated element is provided on a second end winding support.

[0055] Preferably, the unwinding of the third elongated element of the second initial winding support is provided.

[0056] Preferably, the winding of the third element is provided. Petition 870230053695, dated 06 / 22 / 2023, page 21 / 114 / 78 elongated on the first final winding support.

[0057] Preferably, the unwinding of the fourth elongated element of the second initial winding support is provided.

[0058] Preferably, the winding of the fourth elongated element is provided on the second end winding support.

[0059] The Applicant considers that such a method allows the use of pre-existing extrusion lines in a facility configured to extrude pairs of elongated elements that are identical to each other also in a process in which two elongated elements that are different from each other are deposited simultaneously on the forming drum. The Applicant has indeed verified that the parallel winding of the first and second elongated elements that are identical to each other of a first type on a first initial winding support and the parallel winding of the first and fourth elongated elements that are identical to each other of a second type different from the first type on a second initial winding support can be performed on an extrusion line comprising an extruder device from which elongated elements that are identical to each other obtained from the same elastomeric material are simultaneously extruded.The Applicant has verified that the extruder device can, in a first stage, be used to extrude the first type of elongated elements that are identical to each other and, after a change in the elastomeric material to be extruded, can subsequently be used to extrude the second type of elongated elements that are identical to each other. The Applicant has also verified that it is possible to use two extruder devices, each of which is configured to extrude pairs of elongated elements of one of the two types of elongated elements.

[0060] The Applicant also considers that such a method allows the use of pre-existing extrusion lines configured to allow two elongated elements that are identical to each other to be rolled simultaneously in Petition 870230053695, dated 06 / 22 / 2023, page 22 / 114 / 78 a forming drum. The Applicant verified, in fact, that the final winding supports have the capacity to simultaneously unwind two elongated elements that are different from each other, allowing the simultaneous winding on the forming drum of two elongated elements that are different from each other.

[0061] The Applicant also considers that such a method allows the use of pre-existing storage facilities, since they are already configured to store winding supports with elongated wound elements.

[0062] In a second aspect of the same, the invention relates to a process for constructing tires for vehicle wheels.

[0063] This process preferably involves applying the method to arrange elongated elements in accordance with the first aspect of the present invention.

[0066] Preferably, the simultaneous deposition of said first elongated element and said third elongated element or said second elongated element and said fourth elongated element on the forming drum is provided.

[0067] The Applicant therefore considers it possible to simultaneously deposit pairs of elongated elements that are different from each other in a forming drum without having to alter the existing construction lines. Petition 870230053695, dated 06 / 22 / 2023, page 23 / 114 / 78

[0070] Preferably, the initial winding station is also configured to wind a third elongated element and a fourth elongated element of a second type onto a second initial winding support.

[0071] Preferably, the elongated elements of the second type are identical to each other, but different from the elongated elements of the first type.

[0072] Preferably, a transfer device is provided that operates on the first initial winding support.

[0073] Preferably, the transfer device is configured to transfer said first elongated element to a first end winding support.

[0074] Preferably, the transfer device is configured to transfer said third elongated element to the first end winding support.

[0075] Preferably, the transfer device also operates on the second initial winding support.

[0076] Preferably, the transfer device is configured to transfer said second elongated element to a second end winding support.

[0077] Preferably, the transfer device is configured to transfer said elongated fourth element to the second end winding support.

[0078] Preferably, a final unwinding station is provided.

In this way, it is not necessary to have supports of Petition 870230053695, dated 06 / 22 / 2023, page 25 / 114 / 78 winding or other intermediate storage devices for the first and third elongated elements during the transfer from their respective initial winding supports to the first final winding support.

[0089] Preferably, the unwinding of the second elongated element of the first initial winding support is carried out simultaneously with the unwinding of the fourth elongated element of the second initial winding support.

[0091] Preferably, the winding of the second elongated element on the second end winding support is carried out simultaneously with the winding of the fourth elongated element on the second end winding support. Petition 870230053695, dated 06 / 22 / 2023, page 26 / 114 / 78

[0092] The simultaneous unwinding of the second and fourth elongated elements from their respective initial winding supports and their simultaneous winding onto the second final winding support allows for the direct transfer of the second and fourth elongated elements from their respective initial winding support to the second final winding support. Therefore, it is not necessary to have intermediate winding supports or other storage devices for the second and fourth elongated elements during the transfer from their respective initial winding supports to the second final winding support.

[00103] Preferably, the winding of the first elongated element and the second elongated element in parallel comprises associating a first initial service component to the first elongated element and the second elongated element.

[00104] This activity is preferably performed at the initial winding station.

[00105] The first initial service component is preferably associated with a base surface of the first elongated element and the second elongated element. Service components provide the elongated elements with a desired structural consistency, thus preventing the elongated elements from being deformed during winding or unwinding from a winding support. Service components also prevent direct contact of the elastomeric material when the elongated elements are wound onto coils. Petition 870230053695, dated 06 / 22 / 2023, page 28 / 114 / 78

The extrusion line 11 comprises two forming elements 13 configured to operate on a pair of elongated elements exiting the extruder device 12 and obtain a first elongated element 150 and a second elongated element 151 of a first type that are identical to each other. The same extrusion line 11 can be used, after a change in the elastomeric material, to provide a second pair of elongated elements, Petition 870230053695, dated 06 / 22 / 2023, page 54 / 114 / 78 in particular a third elongated element 152 and a fourth elongated element 153 of a second type that are equal to each other and different from the first 150 and the second elongated elements 151.

[00263] Installation 10 also comprises an initial winding station 14 in which the extruded elongated elements are wound onto the initial winding supports. Figure 2 schematically represents an initial winding station 14 operating on the first elongated element 150 and the second elongated element 151. The same initial winding station 14 (or an analogous initial winding station) is configured to operate on the third elongated element 152 and the fourth elongated element 153. Therefore, what will be described in reference to the initial winding station 14 when operating on the first elongated element 150 and the second elongated element 151 is valid for the same initial winding station 14 (or for an analogous initial winding station) when operating on the third elongated element 152 and the fourth elongated element 153.

[00264] The initial winding station 14 comprises a frame 15a in which a first initial winding support 16 that rotates around a respective geometric axis of rotation X1a can be mounted and dismounted. It is also possible to mount and dismount a first auxiliary winding support 17 that rotates around a respective geometric axis of rotation X2a in the frame 15a.

[00265] The first auxiliary winding support 17 is configured to unwind a first initial service component 200. The first initial service component 200 may be a single service fabric configured to receive the first elongated element 150 and the second elongated element 151 in distinct axial positions or it may comprise a first initial service fabric 200a and a second initial service fabric 201a. In the case where the first initial service component 200 is a Petition 870230053695, dated 06 / 22 / 2023, page 55 / 114 / 78 single fabric, it is supplied to a coupling roller 18a. In the case where the first initial service component 200 comprises a first initial service fabric 200a and a second initial service fabric 201a, they are simultaneously supplied to the coupling roller 18a. In both cases, the first elongated element 150 and the second elongated element 151 are also supplied to the coupling roller 18a. In the coupling roller 18a, the first initial service component 200 is coupled to a base surface 150a of the first elongated element 150 and to a base surface 151a of the second elongated element 151 (or the first initial service fabric 200a is coupled to the base surface 150a of the first elongated element 150, and the second initial service fabric 201a is coupled to the base surface 151a of the second elongated element 151).

[00266] The first elongated element 150 and the second elongated element 151 with the first initial service component 200 coupled are thus wound onto coils and simultaneously onto the first initial winding support 16.

[00267] This activity can be performed by motorizing the geometric axis of rotation X1a of the first initial winding support 16 and leaving the coupling roller 18a in idle speed. The geometric axis of rotation X2a of the first auxiliary winding support can be in idle speed or, preferably, slightly braked. Alternatively, both the geometric axis of rotation X1a of the first initial winding support 16 and the coupling roller 18a can be motorized, and the geometric axis of rotation X2a of the first auxiliary winding support 17 can be in idle speed or, preferably, slightly braked. In any case, the winding of the first elongated element 150 and the second elongated element 151 onto the first initial winding support 16 is performed by exerting a pulling or traction action on the initial service component 200 by the first winding support. Petition 870230053695, dated 06 / 22 / 2023, page 56 / 114 / 78 initial 16.

[00268] Similarly, when the initial winding station 14 is used with the third elongated element 152 and the fourth elongated element 153, it is possible to assemble and disassemble a second initial winding support 19 which is rotatable around a respective geometric axis of rotation X1b in frame 15a. It is also possible to assemble and disassemble a second auxiliary winding support 20 which is rotatable around a respective geometric axis of rotation X2b in frame 15a.

[00269] The second auxiliary winding support 20 is configured to unwind a second initial service component 201 in the same ways described above with reference to the first initial service component 200. Also in this case, the second initial service component 201 may be a single service fabric or may comprise a third initial service fabric 202a and a fourth initial service fabric 203a. On the coupling roller 18a, the second initial service component 201 is coupled to a base surface 152a of the third elongated element 152 and to a base surface 153a of the fourth elongated element 153 (or the third initial service fabric 202a is coupled to the base surface 152a of the third elongated element 152, and the fourth initial service fabric 203a is coupled to the base surface 153a of the fourth elongated element 153).

[00270] The third elongated element 152 and the fourth elongated element 153 with the second initial service component 201 coupled are thus wound onto coils and simultaneously onto the second initial winding support 19 in the same ways described in reference to the first elongated element 150 and the second elongated element 151.

[00271] Installation 10 also comprises a storage unit 250 configured to temporarily house the first initial winding support 16 (or a plurality of first initial winding supports) and the second initial winding support 19 (or a plurality of Petition 870230053695, dated 06 / 22 / 2023, page 57 / 114 / 78 (second initial winding supports). The first initial winding support 16 is transferred from the initial winding station 14 to storage 250. Similarly, the second initial winding support 19 is transferred from the initial winding station 14 to storage 250.

[00272] Installation 10 also comprises a transfer device 21 configured to operate simultaneously on the first elongated element 150, the second elongated element 151, the third elongated element 152 and the fourth elongated element 153 wound on the respective first initial winding support 16 and the respective second initial winding support 19.

[00273] The first initial winding support 16 and the second initial winding support 19 are transferred to the transfer device 21 from storage 250. Alternatively, the first initial winding support 16 and the second initial winding support 19 are transferred to the transfer device 21 directly from the initial winding station 14.

[00274] As shown schematically in Figure 4, the transfer device 21 is configured to transfer the first elongated element 150 from the first initial winding support 16 to a first final winding support 22 and to transfer the third elongated element 152 from the second initial winding support 19 to the first final winding support 22. The transfer device 21 is also configured to transfer the second elongated element 151 from the first initial winding support 16 to a second final winding support 23 and to transfer the fourth elongated element 153 from the second initial winding support 19 to the second final winding support 23.

[00275] For this purpose, in transfer device 21, there are two Petition 870230053695, dated 06 / 22 / 2023, page 58 / 114 / 78 intermediate unwinding stations 24, 25. At the final intermediate unwinding station 24, the first initial winding support 16 is activated to unwind the first elongated element 150 and the second elongated element 151 and to decouple the first initial service component 200 from the first elongated element 150 and the second elongated element 151. At the second intermediate unwinding station 25, the second initial winding support 19 is activated to unwind the third elongated element 152 and the fourth elongated element 153 and to decouple the second initial service component 201 from the third elongated element 152 and the fourth elongated element 153.The intermediate final unwinding station 24 is the same as the second intermediate unwinding station 25 (therefore, the same features of the intermediate final unwinding station 24 are present in the second intermediate unwinding station 25).

[00276] Figure 3 represents the intermediate final unwinding station 24 comprising a frame 26a in which it is possible to mount and dismount the first initial winding support 16 which is rotatable around a respective geometric axis of rotation X3a. It is also possible to mount and dismount a first collection winding support 27 which is rotatable around a respective geometric axis of rotation X4a in the frame 26a.

[00277] The first collection winding support 27 is configured to wind the first initial service component 200. The first initial service component 200 is supplied to the first collection winding support 27 from a decoupling roller 28a in which the first initial service component 200 is decoupled from the base surface 150a of the first elongated element 150 and from the base surface 151a of the second elongated element 151.

[00278] This activity can be performed by motorizing the shaft Petition 870230053695, dated 06 / 22 / 2023, page 59 / 114 / 78 geometric rotation axis X4a of the first collection winding support 27 and leaving the decoupling roller 28a in idle speed. The geometric rotation axis X3a of the first initial winding support 16 may be in idle speed or, preferably, slightly braked. Alternatively, both the geometric rotation axis X4a of the first collection winding support 27 and the decoupling roller 28a may be motorized, and the geometric rotation axis X3a of the first initial winding support 16 may be in idle speed or, preferably, slightly braked. In any case, the unwinding of the first elongated element 150 and the second elongated element 151 from the first initial winding support 16 is performed by exerting a pulling or traction action on the first initial service component 200 by the first collection winding support 27.

[00279] Similarly, the second intermediate unwinding station 25 (also shown in Figure 3) comprises a frame 26b in which it is possible to mount and dismount the second initial winding support 19 which is rotatable around a respective geometric axis of rotation X3b. It is also possible to mount and dismount a second collection winding support 29 which is rotatable around a respective geometric axis of rotation X4b in the frame 26b.

[00280] The second collection winding support 29 is configured to wind the second initial service component 201. The second initial service component 201 is supplied to the second collection winding support 29 from the decoupling roller 28b in which the second initial service component 201 is decoupled from the base surface 152a of the third elongated element 152 and from the base surface 153a of the fourth elongated element 153.

[00281] This activity can be performed in accordance with what is described regarding the unfolding and collection of the first component of Petition 870230053695, dated 06 / 22 / 2023, page 60 / 114 / 78 initial service 200.

[00282] The first elongated element 150, the second elongated element 151, the third elongated element 152 and the fourth elongated element 153 are progressively sent to the first end winding support 22 and the second end winding support 23 to be wound onto them while being unwound from the first initial winding support 16 and the second initial winding support 19.

[00283] As illustrated in Figure 1, in the transfer device 21, there are two end winding stations 30, 31. At the first end winding station 30, the first end winding support 22 is activated to wind the first elongated element 150 and the third elongated element 152 immediately after. At the second end winding station 31, the second end winding support 23 is activated to wind the second elongated element 151 and the fourth elongated element 153 immediately after. The first end winding station 30 and the second end winding station 31 are identical to each other and identical to the initial winding station 14 (therefore, the same features of the first end winding station 30 are present in the second end winding station 31 and the initial winding station 14).

[00284] The first end winding station 30 comprises a frame 15b in which it is possible to mount and dismount the first end winding support 22 which is rotatable around a respective geometric axis of rotation X1c. It is also possible to mount and dismount a third auxiliary winding support 32 which is rotatable around a respective geometric axis of rotation X2c in the frame 15b.

[00285] The third auxiliary winding support 32 is configured to unwind a first end service component 300 which is supplied to a coupling roller 18b to which the first elongated element 150 and the third elongated element 152 are also supplied. On the roller of Petition 870230053695, dated 06 / 22 / 2023, page 61 / 114 / 78 coupling 18b, the first final service component 300 is coupled to the base surface 150a of the first elongated element 150 and to the base surface 152a of the third elongated element 152.

[00286] The first elongated element 150 and the third elongated element 152 with the first end service component 300 coupled are thus wound onto coils and simultaneously onto the first end winding support 22.

[00287] This activity can be performed by motorizing the geometric axis of rotation of the first end winding support 22 and leaving the coupling roller 18b in idle speed. The geometric axis of rotation of the third auxiliary winding support 32 can be in idle speed or, preferably, slightly braked. Alternatively, both the geometric axis of rotation of the first end winding support 22 and the coupling roller 18b can be motorized, and the geometric axis of rotation of the third auxiliary winding support 32 can be in idle speed or, preferably, slightly braked. In either case, the winding of the first 150 and the third elongated element 152 onto the first end winding support 22 is performed by exerting a pulling or traction action on the first end service component 300 by the first end winding support 22.

[00288] Similarly, the second end winding station 31 comprises a frame 15c in which it is possible to mount and dismount the second end winding support 23 which is rotatable around a respective geometric axis of rotation X1d. It is also possible to mount and dismount a fourth auxiliary winding support 33 which is rotatable around a respective geometric axis of rotation X2d in the frame 15c.

[00289] The fourth auxiliary winding support 33 is configured to unwind a second end-service component 301 which is supplied to a coupling roller 18c to which the second elongated element 151 and the Petition 870230053695, dated 06 / 22 / 2023, page 62 / 114 / 78 fourth elongated element 153 are also supplied. In the coupling roller 18c, the second end service component 301 is coupled to the base surface 151a of the second elongated element 151 and to the base surface 153a of the fourth elongated element 153.

[00290] The second elongated element 151 and the fourth elongated element 153 with the second end service component 301 coupled are thus wound onto coils and simultaneously onto the second end winding support 23.

[00291] The second elongated element 151 and the fourth elongated element 153 with the final service component 301 coupled are thus wound onto coils and simultaneously onto the second final winding support 23 in the same manner as described in reference to the first elongated element 150 and the third elongated element 152.

[00292] Installation 10 also includes additional storage 251.

[00293] Additional storage 251 is configured to temporarily house the first end winding support 22 (or a plurality of first end winding supports) and the second end winding support 23 (or a plurality of second start winding supports). The first end winding support 22 is transferred from the first end winding station 30 to additional storage 251. Similarly, the second end winding support 23 is transferred from the second end winding station 31 to additional storage 251.

[00294] Additional storage 251 and storage 250 may physically coincide or may be two storages that are physically distinct from each other.

[00295] Installation 10 also comprises a final unwinding station 34 (also illustrated in Figure 3) configured for Petition 870230053695, dated 06 / 22 / 2023, page 63 / 114 / 78 to simultaneously unwind the first elongated element 150 and the third elongated element 152 from the first final winding support 22 and / or to unwind the second elongated element 151 and the fourth elongated element 153 from the second final winding support 23.

[00296] The first end winding support 22 and the second end winding support 23 are transferred to the final unwinding station 34 from the additional storage 251. Alternatively, the first end winding support 22 and the second end winding support 23 are transferred to the final unwinding station 34 directly from the first end winding station 30 and the second end winding station 31.

[00297] At the final unwinding station 34, the first final winding support 22 is activated to unwind the first elongated element 150 and the third elongated element 152 and to decouple the first final service component 300 from the first elongated element 150 and the third elongated element 152. At the final unwinding station 34, it is also possible, alternatively, to activate the second final winding support 23 to unwind the second elongated element 151 and the fourth elongated element 153 and to decouple the second final service component 301 from the second elongated element 151 and the fourth elongated element 153. The final unwinding station 34 is the same as the first unwinding station 24 and the second intermediate unwinding station 25 (therefore, the same features of the first unwinding station 24 and the second intermediate unwinding station 25 are also present at the final unwinding station 34).

[00298] When the first end winding support 22 is activated at the end unwinding station 34, the first end winding support 22 can be mounted and dismounted on a frame 26c and is rotatable around a respective geometric axis of rotation X3c. On frame 26c, it is Petition 870230053695, dated 06 / 22 / 2023, page 64 / 114 / 78, it is also possible to assemble and disassemble a third collection winding support 35 which is rotatable around a respective geometric axis of rotation X4c.

[00299] The third collection winding support 35 is configured to wind the first end service component 300. The first end service component 300 is supplied to the third collection winding support 35 from a decoupling roller 28c in which the first end service component 300 is decoupled from the base surface 150a of the first elongated element 150 and from the base surface 152a of the third elongated element 152.

[00300] This activity can be performed by motorizing the X4c geometric axis of rotation of the third collection winding support 35 and leaving the decoupling roller 28c idling. The X3c geometric axis of rotation of the first end winding support 22 can be idling or, preferably, slightly braked. Alternatively, both the X4c geometric axis of rotation of the third collection winding support 35 and the decoupling roller 28c can be motorized, and the X3c geometric axis of rotation of the first end winding support 22 can be idling or, preferably, slightly braked. In either case, the unwinding of the first elongated element 150 and the third elongated element 152 of the first end winding support 22 is performed by exerting a pulling or traction action on the first end service component 300 by the third collection winding support 35.

[00301] When the second end winding support 23 is activated on the end unwinding station 34, the second end winding support 23 can be mounted and dismounted from the frame 26c and is rotatable around a respective geometric axis of rotation X3d. On the frame 26c, it is also possible to mount and dismount a fourth collection winding support 36 Petition 870230053695, dated 06 / 22 / 2023, page 65 / 114 / 78, which is rotatable around a respective geometric axis of rotation X4d.

[00302] The fourth collection winding support 36 is configured to wind the second end service component 301. The second end service component 301 is supplied to the fourth collection winding support 36 from the decoupling roller 28c in which the second end service component 301 is decoupled from the base surface 151a of the second elongated element 151 and from the base surface 153a of the fourth elongated element 153.

[00303] This activity can be performed by motorizing the X4d geometric axis of rotation of the fourth collection winding support 36 and leaving the decoupling roller 28c idling. The X3d geometric axis of rotation of the second end winding support 23 can be idling or, preferably, slightly braked. Alternatively, both the X4d geometric axis of rotation of the fourth collection winding support 36 and the decoupling roller 28c can be motorized, and the X3d geometric axis of rotation of the second end winding support 23 can be idling or, preferably, slightly braked. In either case, the unwinding of the second elongated element 151 and the fourth elongated element 153 of the second end winding support 23 is performed by exerting a pulling or traction action on the second end service component 301 by the fourth collection winding support 36.

[00304] Installation 10 comprises a construction line 37 in which at least one forming drum 38 is arranged. The forming drum 38 is operationally associated with the final unwinding station 34 to simultaneously receive the two elongated elements that are simultaneously unwound from their respective final winding support.

[00305] In the case where the first elongated element is 150 and the third Petition 870230053695, dated 06 / 22 / 2023, page 66 / 114 / 78 elongated element 152 are simultaneously unwound from the first end winding support 22, the first elongated element 150 and the third elongated element 152 are simultaneously deposited on the forming drum 38.

[00306] In the case where the second elongated element 151 and the fourth elongated element 153 are simultaneously unwound from the second end winding support 23, the second elongated element 151 and the fourth elongated element 153 are simultaneously deposited onto the forming drum 38.

Similarly, the first final winding support 22 comprises a storage reel 41, and the second final winding support 23 comprises a storage reel 42. Such storage reels 39, 40, 41, 42 are identical to each other in structure, and therefore only one storage reel will be described since such a description is also valid for other storage reels.

[00309] Each storage reel 39, 40, 41, 42 comprises a winding surface 43a, 43b, 43c, 43d dimensioned to wind a pair of elongated elements (with the relative service component) into bobbins.

Similarly, the first final winding support 22 comprises a first storage reel 51 and a second storage reel 52, and the second final winding support 23 comprises a first storage reel 53 and a second storage reel 54. Such first storage reels 47, 49, 51, 53 are identical to each other in structure, and therefore only one first storage reel will be described; such a description is also valid for other first storage reels.These second storage reels 48, 50, 51, 52 are identical to each other in structure, and therefore only one second storage reel will be described; this description is also valid for other storage reels.

[00312] The first auxiliary winding support 17, the second auxiliary winding support 20, the third auxiliary winding support 32 and the fourth auxiliary winding support 33 can alternatively be produced according to the embodiments illustrated in Figures 7A and 8A.

[00323] The first initial service component 200 and the second initial service component 201 are schematically represented in Figure 9.

[00324] In a first embodiment, the first initial service component 200 and the second initial service component 201 are band-type elements, axially dimensioned to each receive a pair of elongated elements, and are identical to each other.

The second end-service component 301 comprises a third end-service fabric 304b and a fourth end-service fabric 305b. Such end-service fabrics 302b, 303b, 304b, 305b are identical to each other, and therefore what is described in relation to one of such end-service fabrics 302b, 303b, 304b, 305b is also valid for the others.

[00328] Each end-service fabric 302b, 303b, 304b, 305b comprises a support surface 306a, 306b, 309a, 309b axially dimensioned to receive a single elongated element.

[00338] The first final service component 300 is produced in a single service fabric, and the second final service component 301 is produced in a single service fabric.

[00339] This configuration is particularly effective when the first elongated element 150 and the third elongated element 152 have the same winding diameters (and therefore also when the second elongated element 151 and the fourth elongated element 153 have the same diameter of Petition 870230053695, dated 06 / 22 / 2023, pp. 77 / 114 / 78 (envelope).

[00340] According to this configuration, the first elongated element 150 and the second elongated element 151 are simultaneously wound onto the storage reel 39 of the first winding support 16 in different axial positions with the first initial service component 200 coupled. The first initial service component 200 is unwound from the auxiliary storage reel 62.

The second end service component 301 is unwound from the auxiliary storage reel 65.

[00345] Two storage reels are thus obtained, on each of which two elongated elements are wound that are different from each other and with equal winding diameters.

[00346] After that, the first elongated element 150 and the third elongated element 152 are unwound from the storage reel 41 and simultaneously deposited onto the forming drum 38. The first end-service component 300 is simultaneously separated from its respective elongated elements and collected onto the collection storage reel 87.

The third end service fabric 304a and the fourth end service fabric 305a are unwound, respectively, from the first auxiliary storage reel 76 and the second auxiliary storage reel 77.

[00356] Two storage reels are thus obtained, on each of which two elongated elements are wound that are different from each other and with different winding diameters.
