Embodiment Construction

[0140] exist figure 1 In , reference number 100 generally indicates an exemplary embodiment of a device for inserting a ring-shaped reinforcing element 5 ( Figure 9 ) is placed on the annular anchoring structure 10 of a tire for a vehicle wheel in order to make a reinforced annular anchoring structure 15. The device 100 allows performing a placement process according to the invention.

[0141] like figure 1 , 2 and 9, the annular anchoring structure 10 comprises: a substantially circumferential annular insert 11, also referred to as a bead core; The radially outer position of is connected to said substantially circumferential annular insert 11 .

[0142] Through the device 100 and placement process of the present invention, the annular reinforcing element 5 is attached to the side surface 12a of the filling element 12 of the annular anchoring structure 10 ( Figure 9 ).

[0143] Figure 9 An annular reinforcing element 5 placed at the full radial extension of the side ...

Abstract

A process for depositing an annular reinforcing element (5) on an annular anchoring structure (10) of a tyre for vehicle wheels. The annular anchoring structure (10) comprises at least one substantially circumferential annular insert (11) with which at least one filling insert (12) is associated. The process comprises the steps of: loading the annular anchoring structure (10) onto a service platform (105); - associating the annular reinforcing element (5) with an annular portion of a side surface (12a) of the filling insert (12) in a radially outer position with respect to the substantially circumferential annular insert (11), so as to form a reinforced annular anchoring structure (15); - unloading the reinforced annular anchoring structure (15) from the service platform (105). The reinforced anchoring structure (105) thus obtained can be used in building a carcass structure in the manufacturing of tyres for vehicles.

Description

technical field [0001] The invention relates to a process for the manufacture of tires for vehicle wheels. [0002] The invention also relates to a process and a device for placing annular reinforcing elements on an annular anchoring structure of a tire for a vehicle wheel, which process and said device can be used to implement the above-mentioned process for the manufacture of a tire. Background technique [0003] Tires for vehicle wheels generally comprise a carcass structure comprising at least one carcass ply formed of reinforcing cords contained in an elastic matrix. The end edges of the carcass ply are respectively engaged with annular anchoring structures arranged in regions commonly referred to as "beads" and generally each inserted by a substantially circumferential annular In a radially outer position of said substantially circumferential annular insert, at least one filling insert is applied to said substantially circumferential annular insert. Such annular inse...
