摘要:
The present disclosure provide a method for producing a tread for a tire having a plurality of contacting element delimited by a plurality of grooves and a connecting member. The method includes depositing at least one connecting member on a surface of an unvulcanized green tread, introducing the unvulcanized green tread with the connecting member into a mold having at least one molding element having a plurality of rib for forming the groove on the tread, at least two rib side faces and a molding surface, at least one rib having at least one notching portion receiving a guiding member, moving the connecting member to a predetermined position in the guiding slit through the guiding slit by green tread, molding and vulcanizing the green tread with the connecting member in the mold, and taking a molded and vulcanized tread out from the mold.

Le pneumatique (10) comprend une bande de roulement (12) dans laquelle est ménagé un canal moulé (22, 24). Le canal moulé (22, 24) est interrompu par au moins un sillon (20a-d) de la bande de roulement et s'étend suivant un trajet courbe. De préférence, le trajet du canal moulé (22, 24) est sensiblement parallèle à une surface externe (14) de la bande de roulement (12) dans un plan de coupe radial du pneumatique (10).
摘要:
The invention concerns a running tread (1) with total thickness E for a tyre, comprising, when new, a running surface (2) designed to be in contact with the road surface when running, a plurality of first cutouts (10) (grooves, incisions) with depth less than the thickness (E) of the tread and delimiting tread pattern elements of height less than the tread total thickness, a plurality of subjacent cavities (20) at the running surface (2) when new and extending over an average length L, each of said cavity being designed to form at least a new groove or incision after the tread has been partly worn, each cavity (20) limited by the running tread gum having a greater generatrix (21) beneath the running surface (2) when new. Said running tread is characterized in that for each cavity (20), the upper generatrix (21) follows an undulated profile and comprises a series of recesses and protuberances, the amplitude of said recesses and protuberances being at least 10 % of the depth of the newly created grooves or incision.
摘要:
The present disclosure is related to a molding element for a mold used for manufacturing a tire. The molding element has a molding surface for forming a contact face of the contacting elements and a rib for forming the groove between adjacent contacting elements, at least two rib side faces forming the side faces of the contacting element, the rib having a notching portion, a guiding member made of a material different from a material of the molding element is received in the notching portion and has two opposite side faces configured to form a part of the side faces of the contacting element and a top face configured to form a part of a bottom of the axial groove.
摘要:
Vulkanisationsform für einen Fahrzeugluftreifen, welcher einen Laufstreifen mit Profilpositiven mit parallel zueinander bzw. im Wesentlichen parallel zueinander verlaufenden Einschnitten (8) aufweist, mit den Laufstreifen ausformenden Formteilen (1), in welchen Einschnitte (8) ausbildende Lamellenbleche (2) verankert sind und welche mit Rillen ausformenden Profilstegen (3) versehen sind, wobei die Lamellenbleche (2) jeweils einen innerhalb des Formteiles (1) befindlichen Verankerungsteil (2a) und einen den Einschnitt im Laufstreifen ausformenden Teil (2b) aufweisen, und wobei bei den Lamellenblechen (2) von der Innenseite (1a) des Formteiles (1) ausgehend zumindest ein Entlüftungskanal (4) in den Formteil (1) hinein verläuft. Der Entlüftungskanal (4) ist an der Verankerungsposition des Lamellenbleches (2) ausgebildet, durchsetzt jeweils den Verankerungsteil (2a) des Lamellenbleches (2) in radialer Richtung, wobei in dem den Einschnitt ausformenden Teil (2b) des Lamellenbleches (2) in Fortsetzung des Entlüftungskanals (4) eine Aussparung (5) ausgebildet ist.
