摘要:
Die Erfindung betrifft ein Verfahren und Markiervorrichtung zum Markieren eines Reifens (40), wobei das Verfahren folgende Verfahrensschritte aufweist: a) ein zu markierender Reifen (40) wird zu einer Markiervorrichtung (10) gefördert; b) zumindest ein Teilbereich des Reifens (40) wird mittels einer Messeinrichtung (100) optisch erfasst; c) ein dem Reifen (40) zugeordneter Referenzdatensatz (DSR) wird in die Steuereinrichtung (300) geladen; d) die Steuereinrichtung (300) berechnet eine Abweichung (ApD) zwischen den Soll-Positionsdaten (PDR) und den Ist-Positionsdaten (PDM) und generiert das Steuersignal (SL) für die Lasereinrichtung (200) unter Berücksichtigung der berechneten Abweichung; e) die Lasereinrichtung (200) wird mittels des Steuersignals in einer Markierposition positioniert und in Bezug auf die Ist-Position des Markierfelds (51, 52) ausgerichtet; f) die Markierung (400) wird mittels der Lasereinrichtung (200) in dem Markierfeld (51, 52) erzeugt. Weiterhin betrifft die Erfindung eine Haltevorrichtung (17) für die Markiervorrichtung.
摘要:
L'invention concerne un procédé pour déposer au moins une couche colorée sur la surface d'un flanc de pneumatique vulcanisé. Ce procédé se caractérise en ce qu'il consiste à appliquer une couche colorée sur la totalité dudit flanc ou sur au moins une partie du flanc dudit pneumatique par jet d'encre, puis, après séchage, à enlever de manière sélective la couche colorée de manière à créer un premier motif. L'invention concerne également un pneumatique obtenu à l'issu de ce procédé.
摘要:
A run-flat tire and method of manufacturing is disclosed with a pair of post-cure sidewall-stabilizing run-flat inserts. Each of the pair of post-cure sidewall-stabilizing run-flat inserts extends circumferentially about a rotational axis of a tire; includes a first terminating end, and a second terminating end, opposite the first terminating end; and is disposed on a radially inner surface of a sidewall of a tire such that the first terminating end terminates above the bead core and the second terminating end terminates along at least one of the sidewall and a respective adjacent shoulder.

The invention related to a method of colouring portions of a tyre and to a tyre obtained by said method. The method includes: - forming a highly impermeable protective layer by depositing an aqueous emulsion on a part of the tyre to be coloured; and - depositing a coloured layer on the protective layer. The aqueous emulsion has at least a cross - linkable polymer base, and a surfactant of molecular formula (I) : (R 1 CONR 2 CHR 3 COO - ) n X n+ where R 1 is an aliphatic group C 6 -C 23 , R 2 is H or an aliphatic group C 1 - C 8 , R 3 is H or an aliphatic or aromatic group C 1 - C 8 , X is a metal cation, preferably an alkaline cation, and n is an integer of 1 to 3.

The invention relates to a method for producing a tyre, especially a tyre for a motor vehicle, comprising gradually constructing a tyre with a layer which is, wherever possible, substantially airtight, at least one casing ply (3), horn profiles, bead cores, side walls as well as a belt web composed where appropriate of a belt layer (13) in one or more parts and a tread (15). According to said process, the rubber of the tyre side walls is wound as an extruded rubber web (8) in the form of a spiral with several adjacent or partially overlapping windings (28a) on the side walls of a carcass which is at least previously curved and optionally provided with at least several parts of the belt assembly.

To apply inscriptions disposed in a circle and the like to the visible surface near the tread of a vehicle tyre by vulcanization without having to remove the tyre from the rim, an apparatus has a rotary table (3) on which the tyre (R) to be treated is laid. The table can be set in rotation by a shaft secured to the table so as to remained fixed during rotation. A heated application wheel (19) mounted in a housing (18) acts on the tyre surface to which it is adjustably applied under pressure. A vulcanizable coloured strip applied to a backing layer and taken from a reserve is vulcanized on to the tyre below the application wheel (19) by rotation of the rotary table (3).
摘要:
An apparatus for vulcanising and moulding tyres comprises a vulcanisation mould (100), a tyre loader (21) configured for loading a green tyre (2) to be moulded and vulcanised in the vulcanisation mould (100) and a label transfer member (31). The label transfer member (31) comprises: a support portion (35), configured for retaining a label (26) to be arranged in the vulcanisation mould (100), and a grip portion integral with the support portion (35). The tyre loader (21) is also configured for clasping the grip portion and moving the label transfer member (31) between a position spaced from the vulcanisation mould (100) and a position of engagement with the vulcanisation mould (100). In the engagement position, the label transfer member (31) is configured in order to release the label (26) in the vulcanisation mould (100) before the vulcanisation mould (100) receives the green tyre (2) to be moulded and vulcanised.
