1. Process for the production of a cast tyre reinforced with sheathed cord threads (7) in which first of all the tyre reinforcement (12) is prefabricated by winding a continuous cord thread (7) in an alternating manner on to a core (6, 10), the alternation being controlled in such a manner that, at the turning points of the alternation, the continuous cord thread (7) is guided for a certain time in a rotationally symmetric manner in the region of the tyre foot (13), characterised by the following process steps : a) the continuous cord thread (7) is wound on to a rotating core (6, 10) with non-narrowing flanks ; b1) either the wound core (6, 10) is used to form the core internal contour of the cast tyre, or b2) the tyre reinforcement (12) is removed from the core (6, 10) after a fixing operation and is introduced into a tyre-casting mould (14) ; c) the alternation is controlled in such a manner that, at the turning points of the alternation, the continuous cord thread (7) is pressed at least once on each side for the duration of at least one rotation against a bead (3) provided in a rotationally symmetric manner on the core (6, 10) in the region of the tyre foot (13). |
