    Abstract: A method of selectively controlling the self-sealing ability of a tyre obtained by application of a sealing assembly on a drum and subsequent formation thereon of a precursor of a green tyre inclusive of liner and carcass, followed by shaping, curing and molding. The sealing assembly includes: a self-supporting thermoplastic film of polyamide or polyester and a layer of sealing material possessing viscoelasticity and stickiness features, which is associated with and supported by the self-supporting thermoplastic film. The sealing assembly is easily puncturable by a sharp-pointed element while it maintains such a deformability and stickiness that it helps in the transfer of the sealing material during ejection of the sharp-pointed element and limits the transferred material amount to such an extent that holes bigger than a predetermined value are not sealed.

    Abstract translation: 选择性地控制通过在滚筒上施加密封组件并随后在其上形成包括内衬和胎体的生胎的前体，随后成型，固化和模制而获得的轮胎的自密封能力的方法。 密封组件包括：聚酰胺或聚酯的自支撑热塑性膜和具有粘弹性和粘性特征的密封材料层，其与自支撑热塑性膜相关联并由其支撑。 密封组件可以通过尖锐的元件容易地刺穿，同时保持这种可变形性和粘性，这有助于在尖锐的元件喷射过程中密封材料的转移，并将转移的材料量限制到这样的程度 大于预定值不被密封。

    Abstract: A plant (1) for looping annular anchoring structures (100) includes a looping device (2), a separation station (8a) and a coupling station (8b). A handling apparatus (3) is interlocked to the looping device (2) for managing the plant (1) by moving the plurality of annular anchoring structures (100) coupled to respective separation elements (300), the looped annular anchoring structures (200) coupled to respective separation elements (300) and the separation elements (300a). The separation elements (300) are fed, coupled to respective annular anchoring structures (100), along a feeding section (A1). The separation elements (300a) separated by respective annular anchoring structures (100, 200) are transferred from the separation station (8a) to the coupling station (8b) along a transfer section (T), stationing in at least a first intermediate station (11, 11a). The separation elements (300) are moved away, coupled to respective looped annular anchoring structures (200), along a moving-apart section (A2).

    Abstract: In a process for producing self-sealing tires for vehicle wheels, a continuous sealing assembly, including a self-supporting thermoplastic film and a layer of polymeric sealing material, is wound from a reel holder on which is stocked, separated by a protective film associated with the layer of polymeric sealing material, cut to size and then wound around a forming drum. Winding the sealing assembly cut to size includes: feeding the sealing assembly cut to size onto a chute from top to bottom up to the forming drum; depositing a leading end of the sealing assembly cut to size on a radially outer surface of the forming drum; locking the leading end on the forming drum by means of a locking bar; setting the forming drum in rotation with the locking bar dragging the sealing assembly cut to size and winding it on the forming drum up to overlapping; and sealing a trailing end of the sealing assembly cut to size on the leading end.
