Tasit tekerleklerinin lastikleri için karkas yapisinin imaline mahsus yöntem ve sözkonusu yöntemle elde edilen bir karkas yapi.

摘要

Formation of a carcass ply takes place by laying down onto a toroidal support (11), a first and a second series of strip-like sections (13, 14) cut to size from a continuous strip-like element (2a) and each comprising longitudinal thread-like elements (15) incorporated into a layer of elastomer material (18). The sections (13) of the first series are sequentially disposed at some circumferential distance from each other, to form side portions (19) to the end flaps (19a) of which primary portions (4a) of respective bead-reinforcing structures (4) are applied. The sections (14) of the second series are each interposed in the space defined between two sections of the first series (13), with the respective end flaps (20a) overlapping the primary portions (4a) of the annular structures (4). Additional portions (24) of the annular structures are applied to the end flaps (20a) of the sections (14) belonging to the second series.
