Description

4. Tubular tires according to one of the preceding Γ and 2 'of the two layers 1 and 2 are opposed to c .: the claims, characterized in that offset in the other. The fabric insert is on the outside. The inside of the tire is covered with an outer jacket 3 on the side on the wheel rim, which is covered by ck seated zone a reinforcement (5) arranged 25 outer rubber coating of the outer layer 1 ί · is. forms is. On the inside the fabric egg carries;

lay an airtight inner jacket4 from the inner Rubber layer of the inner layer 2 bi stands. As can be seen from Fig. 1, is on the inside jacket 4 a fabric tape as reinforcement 5 and au: the reinforcement 5 is a band 6 of rubber of the same; Width applied. The mutual gluing of reinforcement 5 and 6 is prevented with the help of an anti-gluing agent (for example zinc stearate). This i i f diji Si d V

The invention relates to a tubular tire for two-wheelers, which has a tread, a sealing Inner jacket, an outer protective jacket and

(p)

a fabric insert made of two layers of intersecting anti-adhesive agents is placed on the side of the reinforcement cords has k5 aftn di in touch with volume 6

Has cords.

With the tubular tires currently in use, the ends of the sidewalls are connected by means of a seam, which is located in the area of the tubular tire sitting on the wheel rim zone. This seam is covered with a rubberized fabric tape, which forms a joint strip, the tubular tire there is a hold on the rim and it is supported by the ends of the rim passing through from the outside of the rim Keeps wheel spokes away.

Such tubular tires are not free from disadvantages. In particular, the lacing system is expensive, not very practical, and the tire is too heavy, which is particularly important when it is used Has an unfavorable effect on racing bikes.

In another known tubular tire, the ends of the two layers of the fabric insert are also connected to one another by overlapping in the area of the zone resting on the wheel rim. This tire also has the disadvantages mentioned above.

The invention has the task of remedying the deficiencies described and a particularly easy, easy to manufacture and resistant

Fig. 2 shows the tire after kicking back of the right and then the left end of the layers i and 2. In addition, the applied tread 7 can be seen. After rolling in the unvulcanized state, the tubular tire is brought into a shape, where it is vulcanized after its inflation.

3 shows a section through the finished tubular tire. The reinforcement 5 and the tape 6 separated from each other when the tubular tire was inflated. The outer layer 1 with the outer jacket 3 on the one hand and the inner layer 2 with the inner jacket 4 on the other hand are below the tread 7 butt welded together. The tread 7 and the belt 6 form on the outside or the inside of the tire covers the welding points.

In the drawing, the valve of the tubular tire is not shown. Before the Band 6 and used after a perforation in the wall of the tubular tire.

The assembly of the tire according to the invention is

Creating tubular tires that have a secure fit 60 is very easy. You only need it by deforming it

on the rim. in its position on the rim. After

According to the invention, this object is achieved in that the reinforcement 5 holds the tubular tire

solves that the ends of the layers of the fabric insert un- firmly on the rim.
