摘要： Provided is a stretching device for stretching an apex filler strip prior to application to a bead for a tire. The stretching device includes a stretching roller and a plurality of guide rollers for guiding the apex filler strip in a loop around the stretching roller. The plurality of guide rollers is arranged for receiving the apex filler strip in an entry orientation and for discharging the apex filler strip in an exit orientation. The plurality of guide rollers is arranged for guiding the one side of the apex filler strip in the entry orientation and the exit orientation under angles different from the support angle (H) with respect to rotation axis (R) of the stretching roller such that the apex filler strip is twisted over a twisting angle of at least forty-five degrees.

摘要： Provided is a pneumatic tire which is configured so as to prevent carcass cords from biting into an inner liner, thereby improving the durability performance of the tire. A pneumatic tire (1) is provided with a carcass (6) which comprises a carcass ply (11) extending from a tread (2) through side walls (3) to the bead cores (5) of bead sections (4), the bead cores (5) each including an inner core (14) and an outer core (15). The carcass ply (11) is sandwiched between the inner cores (14) and the outer cores (15). Each of an inner core (14) and an outer core (15) includes a bead cord (16) which is wound at least one turn in the circumferential direction of the tire. Each of the bead cords (16) includes an outermost layer (18) formed by twisting filaments (17) together. In at least one bead section, the outermost layer (18) of the bead cord (16) of each of the inner core (14) and the outer core (15) is twisted in the direction which allows the carcass ply (11) to easily move to the outside in the radial direction of the tire from between the inner core (14) and the outer core (15).

摘要： Die Erfindung betrifft einen elastomeren Gegenstand mit mindestens zwei Enden, wobei mindestens ein Ende eine Öffnung mit einem Befestigungswulst aufweist, der mit einem Wulstkern verstärkt ist, wobei mindestens ein Wulstkern aus Kunststoff (6) mit eingebetteten Verstärkungsfasern besteht. Der Erfindung liegt die Aufgabe zu Grunde, einen elastomeren Gegenstand zu schaffen, bei dem mindestens ein Wulstkern aus Kunststoff ausgebildet ist, der bei hoher Festigkeit und zu angrenzenden Befestigungsteilen korrespondierender Längenausdehnung einfach herstellbar ist. Diese Aufgabe wird dadurch gelöst, dass der mindestens eine Wulstkern in einem Spritzguss-Verfahren hergestellt wird, wobei der spritzgegossene Wulstkern Verstärkungsfasern umfasst, die mindestens teilweise in Umfangsrichtung des Wulstkernes ausgerichtet sind. Die Aufgabe wird weiterhin dadurch gelöst, dass der Wulstkern durch ein Verfahren mit folgenden Arbeitsschritten hergestellt wird, nämlich
- Einspritzen eines einen Verstärkungsfaseranteil aufweisenden Kunststoffmaterials (6) in ein einen Wulstkern abbildendes Spritzgusswerkzeug (1),
- Einbringen einer rotatorischen Relativbewegung (13) in mindestens einen Teil des Werkzeugs (2, 3, 4, 5) zur Erzeugung einer laminaren Strömung in Umfangsrichtung des Wulstkerns ähnlich einer Couette-Strömung mindestens in Teilen des Kunststoffmaterials.
Durch eine rotatorische Relativbewegung der Werkzeugteile (2, 3, 4, 5) zueinander während des Herstellprozesses werden die Verstärkungsfasern in der Kunststoffmatrix in Umfangsrichtung ausgerichtet, da sich durch die Rotation der mit dem Kunststoff im Kontakt stehenden Werkzeugteile (2, 3, 4, 5) wegen der Reibung zwischen den Kontaktflächen (11, 12) der Werkzeugteile (2, 3, 4, 5) und dem Kunststoff der Kunststoff mit den Fasern in eine laminare Strömung in Umfangsrichtung des Wulstkerns ähnlich einer Couette-Strömung mitreißen lässt. In Folge dessen richtet sich in mindestens einem Übergangsbereich zwischen den Kontaktflächen (11, 12) mindestens ein Teil der Verstärkungsfasern in Umfangsrichtung aus.
