Abstract
Abstract A method for molding a tire with an annular reinforcement below the tread surface in which first a tire body is molded and then a flexible reinforcement formed by bands or threads is wound, preferably under tension, in form of a helix about the circumference of the tire body, whereafter a tread surface portion is molded about the tire body and the reinforcement thereon; and an apparatus for carrying out the method.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
61 words
A method for producing a tire with a reinforcement below the tread surface of the tire, comprising the steps of molding a tire body about a core; subsequently winding a reinforcement in circumferential direction about the circumference of the tire body; and finally molding a further portion of the tire about the reinforcement to form the tread surface of the tire.
Claim 2
Independent Claim
61 words
A method for producing a tire with a reinforcement below the tread surface of the tire, comprising the steps of molding a tire body about a core; subsequently winding a reinforcement in circumferential direction about the circumference of the tire body; and finally molding a further portion of the tire about the reinforcement to form the tread surface of the tire.
Claim 3
Dependent Claim
12 words
A method as defined in claim 1, wherein said reinforcement comprises bands.
Claim 4
Dependent Claim
12 words
A method as defined in claim 1, wherein said reinforcement comprises threads.
Claim 5
Dependent Claim
24 words
